The structures of the parameter memory
1008
and the locating-program memory
1009
of the locating controller
1001
and those of the parameter memory
1016
and the locating-program memory
1018
of the location programming apparatus
1004
are the same.
As described above, the conventional location programming apparatus
1004
is structured in such a manner that the locating program and parameters are set on the parameter list window so that the locating program is set by using the list form. Therefore, all of position data, speed data and parameters are set by inputting figures and displayed in the form of figures. Thus, when the initial programming process is performed, the locus of the locations and a diagram of the speed pattern during the operation must be calculated and constructed. Moreover, a substituting process for the values of the program and parameters of the list form in accordance with the constructed diagram. Therefore, there arises a problem in that excessively long time takes to set the parameter and the parameters.
When the set values are changed because debugging of the program is performed, calculations must again be performed. As a result, long time is required to determine figures. Moreover, there arises a problem in that the control operation affected by the changed parameter cannot easily detected.
Since the conventional location programming apparatus
1004
has the structure that the programs for setting the parameters and position use lists which requires figures to be input, there arises a problem in that the actual operation of the subject which must be controlled cannot easily be recognized by simply looking the program and the parameters.
To solve the above-mentioned problems, an object of the present invention is to obtain a location programming apparatus and a method therefor with which the operations for controlling the position and the speed are graphically displayed to enable anyone to easily understand the control operation, the graph can easily be constructed/changed and direct substitution for the locating program and parameters is permitted.
Since the conventional location programming apparatus has the structure that the programs for setting the parameters and position use lists which requires figures to be input, the functions of the items set by the programs for setting the parameter and the position in the control operation of the determined locating control type cannot easily be recognized. Moreover, the relation of the items with the control operation cannot easily be recognized.
The present invention is achieved to solve the above-mentioned problems and an object of the present invention is to obtain a location programming apparatus and a method therefor capable of graphically displaying a graph for enabling the relation of items with the control operation in the determined type of the locating control and the programs for setting the parameter and the position to easily be understood so as to easily set/change a graph pattern and enable substation for the locating program and parameters.
Since the conventional location programming apparatus is arranged to set a locating program by using the list form, all of position data items are set by inputting figures. When a subject, which must be controlled, is located by performing interpolation of a plurality of axes, such as interpolation of three spindles or four spindles, the locus chart which is previously constructed when the initial programming operation is performed becomes too complicated. Thus, there arises a problem in that excessively long time is required to set a program.
Since the conventional location programming apparatus uses a locating program in the form of a list, there arises a problem in that the locus operation of a subject which must be controlled cannot easily be understood by simplifying looking the program.
Since the conventional location programming apparatus uses a locating program in the form of a list, a result of change of a locus cannot easily be understood when position data of the program has been changed. Therefore, there arises a problem in that long time is required to determine position data.
The present invention is achieved to solve the above-mentioned problems and an object of the present invention is to obtain a location programming apparatus and a method therefor capable of easily graphically constructing and changing the locus of a subject which must be controlled even if a plurality of axes are interpolation-controlled and permitting direct substitution for a locating program.
Since the conventional location programming apparatus uses a locating program in the form of a list, there arises a problem in that whether position data is instructed with an absolute position or an amount of relative movement cannot quickly be recognized by only looking at the program depending on the program language.
The present invention is achieved to solve the above-mentioned problem and an object of the present invention is to obtain a location programming apparatus and a method therefor which enables a method of instructing the position to be recognized by only looking at the locus.
Since the conventional location programming apparatus uses a locating program in the form of a list, there arises a problem in that an amount of relative movement between points or a corresponding absolute position cannot immediately be recognized by only looking at the program for controlling the locus of a type in which different methods of instructing the position are mixed.
The present invention is achieved to solve the above-mentioned problem and an object of the present invention is to obtain a location programming apparatus and a method therefor with which enables the absolute position of each point and an amount of relative movement between points to immediately be recognized only by looking even if a locus control program is employed.
Since the conventional location programming apparatus is arranged in such a manner that location programming and setting of locating control parameter, such as the stroke limit, are performed on individual windows, the window must be switched to change/confirm the parameter during the location programming process. Thus, there arises a problem in that a complicated switching operation is required.
Another problem arises in that position data is set without consciousness of a stroke limit when a location programming process is performed and the controller detects an error deviated from the stroke limit range. Thus, start of the operation is sometimes inhibited.
If the start and auxiliary points which are set by the program satisfy the stroke limit range when the circular interpolation is set, deviation of the intermediate path of the circular arc from the stroke limit range cannot be detected when the programming operation is performed. Thus, the controller detects an error deviated from the stroke limit range when the program is started. Therefore, there arises a problem in that the operation is undesirably interrupted.
To solve the above-mentioned problem, an object of the present invention is to obtain a location programming apparatus and a method therefor with which the stroke limit range and the locating locus can always be recognized.
The conventional location programming apparatus is arranged in such a manner that all of data items of, for example, instructed speed, limited speed, acceleration time, deceleration time and rapid stop deceleration time, for controlling acceleration and deceleration are set by inputting figure. Therefore, a speed pattern which is being employed during the operation cannot easily be recognized. To determine a speed pattern, confirmation of the operation by using a machine is required. To modify/change the operation, figures must again be obtained and set followed by confirmation using the machine. Thus, there arises a problem in that excessively long time is required to determine figures and a complicated operation is required.
The conventional location programming apparatus is arranged in such a manner that instructed speed is set on a location programming window in the form of a list. Moreover, data of limited speed, acceleration time, deceleration time and rapid stop deceleration time for controlling acceleration and deceleration is set on a parameter list window. Therefore, data relating to the speed must be set on an individual window. As a result, the relation cannot easily be recognized. Thus, the window must be switched to change/confirm the parameters during the location programming operation. As a result, there arises a problem in that a complicated operation must be performed.
To solve the above-mentioned problem, an object of the present invention is to obtain a location programming apparatus and a method therefor with which a speed pattern for use in the operation can easily be produced/changed and direct substitution for the acceleration/deceleration parameter and for a locating program is permitted.
The conventional location programming apparatus is arranged in such a manner that the location programming window in the form of a list is used to set instructed speed and limited speed is set on a parameter list window by using figures. Therefore, there arises a problem in that instructed speed higher than limited speed is unintentionally set when location programming is performed. As a result, the controller detects an error of a type that the speed is higher than the instructed speed. Thus, there arises a problem in that control to realize instructed speed cannot be performed.
To solve the above-mentioned problem, an object of the present invention is to provide a location programing apparatus and a method therefor with which limited speed can always be recognized during the location programming operation and an error of a type that the speed is higher than the instructed speed can be prevented.
The conventional location programming apparatus is arranged in such a manner that data for controlling the acceleration/deceleration pattern by inputting figures. Therefore, there arises a problem in that an employed pattern for controlling the acceleration/deceleration cannot easily be recognized.
To solve the above-mentioned problem, an object of the present invention is to provide a location programming apparatus and a method therefor with which an actual acceleration/deceleration pattern to be displayed is formed into a speed graph and setting/change is permitted.
The conventional location programming apparatus is arranged in such a manner that a parameter list window is used to set limited speed, acceleration time, deceleration time and rapid stop deceleration time by inputting figures. Therefore, actual acceleration time, deceleration time and rapid stop deceleration time which take in the operation when the speed instructed by the locating program is realized cannot easily be recognized. Thus, there arises a problem in that a user must perform calculations to recognize the time.
If an operation speed pattern is, in a locus control, employed with which the speed is changed at an intermediate passing point, there arises a problem in that actual acceleration/deceleration time at the point at which the speed is changed cannot easily be recognized.
To solve the above-mentioned problem, an object of the present invention is to provide a location programming apparatus and a method therefor with which actual acceleration time, deceleration time and rapid stop deceleration time from the speed instructed by using the locating program can automatically be calculated and displayed.
The conventional location programming apparatus is arranged in such a manner that the list-form locating program is used to set dowel time, the M code and limited torque by inputting figures. Therefore, there arises a problem in that the control operation which is performed during the operation cannot easily be recognized.
To solve the above-mentioned problem, an object of the present invention is to provide a location programming apparatus and a method therefor with which the ratio of dowel time, timing at which the M code must be transmitted and an effective range of the limited torque can visually be recognized when the location programming is performed.
The conventional location programming apparatus suffers from a problem in that the speed of each axis with respect to instructed speed cannot be detected when two or more axes are interpolation-controlled.
To solve the above-mentioned problem, an object of the present invention is to provide a location programming apparatus and a method therefore with which the speed of each axis can graphically be displayed when interpolation control is performed.
The conventional location programming apparatus has a problem in that acceleration distance, deceleration distance and rapid stop deceleration distance which are determined in accordance with the instructed speed, acceleration time, deceleration time and rapid stop deceleration time cannot be detected when the programming operation is performed. That is, there arises a problem in that the distance for which movement is required to realize the instructed speed and the distance required to make the instructed speed to be reduced to completion of movement cannot directly be detected.
To solve the above-mentioned problem, an object of the present invention is to provide a location programming apparatus and a method therefor capable of graphically displaying a distance of movement required to change the speed from the instructed speed, acceleration time, deceleration time and rapid stop deceleration time.
The conventional location programming apparatus has a problem in that the relationships among the rated number of revolutions, maximum number of revolutions and the instructed speed must previously be calculated from parameters.
To solve the above-mentioned problem, an object of the present invention is to provide a location programming apparatus and a method therefor a reference to the rated number of revolutions and maximum number of revolutions of the motor can easily be performed when the speed or the instructed speed is determined.
The conventional location programming apparatus has a problem in that only information, such as acceleration time and deceleration time, relating to the acceleration and formed into figures can be obtained and thus the acceleration cannot directly be determined.
To solve the above-mentioned problem, an object of the present invention is to provide a location programming apparatus and a method therefor with which acceleration time and deceleration time can be changed by changing the acceleration.
The conventional location programming apparatus uses a list-form locating program and an effective region in which the speed can be changed is not displayed. Therefore, there arises a problem in that a user must perform complicated calculations to detect the region.
Another problem arises in that requested change in the speed is performed during control of a type in which speed change during the operation is not permitted or in a region in which the speed change is ineffective and thus the controller detects an error.
To solve the above-mentioned problem, an object of the present invention is to provide a location programming apparatus and a method therefor with which an effective region in which speed can be changed can previously be detected when the locating programming is performed.
The conventional location programming apparatus has a problem in that the control operation cannot easily be understood by looking the list-form locating program and a parameter list. Another problem arises in that a control original point which will be affected by the change in the list-form locating program or that in the location control parameter cannot easily be recognized.
To solve the above-mentioned problem, an object of the present invention is to provide a location programming apparatus and a method therefor with which the control operation can easily be understood in accordance with a graph displayed by a list-form locating program and a control operation which is affected by change in the list-form locating program can easily be understood.
An object of the present invention is to provide a location programming apparatus and a method therefor with which a process for the operation pattern of a produced graph to be changed to a list-form locating program can easily be recognized.
The conventional location programming apparatus has a problem in that whether or not a program can be used in a circular interpolation operation cannot easily be determined when locating programming is performed to perform circular interpolation. Thus, there arises a problem in that the controller cannot be started when the program is started because of an error of a type that the position is deviated from the circular interpolation radius or a permissible range for the circular interpolation.
To solve the above-mentioned problem, an object of the present invention is to provide a location programming apparatus and a method therefor with which a set range in which the circular interpolation operation is permitted can be recognized when programming is performed.
The conventional location programming apparatus has the structure that setting required for a locating program is performed by using a list. Therefore, there arises a problem in that an amount of movement of a speed reference axis for use in the liner interpolation cannot easily be detected. Thus, the conventional apparatus suffers from a problem in that the controller cannot be started when the program is started because the amount of movement of the reference axis is zero.
To solve the above-mentioned problem, an object of the present invention is to provide a location programming apparatus and a method therefor with which an axis which can be employed as the speed reference axis for use in the linear interpolation can be recognized when programming is performed.
The conventional location programming apparatus has the structure that setting required for a locating program is performed by using a list. Therefore, a program is unintentionally determined with which deceleration cannot be completed at the determined speed or within the amount of movement which is performed in the employed speed/position switching control depending on the employed deceleration pattern. Thus, there arises a problem in that an overrun error occurs in that the amount of movement exceeds a determined value during execution of the program. In some cases, there arises a problem in that a collision of the machine occurs.
Since excessively large deviation takes place when the speed/position is switched during the execution of the program, there arises a problem in that an overrun error occurs in that the amount of movement exceeds a determined value. In some cases, there arises a problem in that a collision of the machine occurs.
To solve the above-mentioned problem, an object of the present invention is to provide a location programming apparatus and a method therefor with which an amount of movement which is performed in speed/position switching control which corresponds to a speed pattern and which can be employed can be recognized when programming of the speed/position switching control is performed and permissible deviation with respect to the determined amount of movement can be recognized when programming is performed.
The conventional location programming apparatus is arranged in such a manner that data for returning to the original point is set by using only numerical data. Therefore, there arises a problem in that the speed pattern for use in control for returning to the original point by a dog method and control for returning to the original point by a count method cannot easily be detected.
The length of the near dog is too short depending on the speed at which returning to the original point is performed and the determined creep speed. Thus, there arises a problem in that deceleration to the creep speed cannot be performed and thus overrun takes place. As a result, normal returning to the original point cannot be performed.
When count method returning to the original point is performed, setting of an insufficient amount of movement after the near dog as compared with a deceleration distance from the speed at which returning to the original point is performed cannot be found. Thus, there arises a problem in that overrunning takes place which exceeds the determined amount of movement during execution of the program and thus normal returning to the original point cannot be performed.
To solve the above-mentioned problem, an object of the present invention is to provide a location programming apparatus and a method therefor with which the length of a near dog required to decelerate the speed from the speed at which returning to the original point to the creep speed and the deceleration distance from the from the speed at which returning to the original point is performed can easily be recognized when programming for returning to the original point is performed.
The conventional location programming apparatus is arranged in such a manner that programming for control, such as high-speed oscillation, with which a reciprocating operation is performed in accordance with a sine wave is performed by only inputting figures. Therefore, there arises a problem in that an actual operation cannot easily be recognized during the programming operation.
To solve the above-mentioned problem, an object of the present invention is to provide a location programming apparatus and a method therefor with which programming of a high-speed oscillation function can be performed in such a manner that the actual operation is recognized.
A first conventional locating mode has been described. A second conventional locating mode will now be described.
Hitherto, control of a plurality of axes each of which repeats a predetermined operation has been performed by a controller with which a locating program for each axis is produced and which is arranged to administrate the start timing of the locating program in accordance with the operation timing of each axis.
When a motor for moving a subject, which must be controlled, is controlled to locating the subject to three points apart from one another for arbitrary intervals made up of
1030
a
-
1030
u
as shown in
FIG. 195
, locating programs by a number corresponding to the locating patterns must be produced. When some locating programs are sequentially started, a sequencer or the like is required to administrate the start timings.
Referring to a flow chart shown in
FIG. 197
, a sequence program will now be described. Initially, locating programs
1031
a
,
1031
b
and
1031
c
as shown in FIG.
196
and corresponding to the number of locating points are produced (step S
1100
).
Then, the program
1031
a
for a first axis which is first operated is started by a sequencer (step S
1101
). After the starting operation has been performed, whether or not the locating program
1031
a
for the first axis has been completed is administrated by a sequencer program (step S
1102
). If the completion is confirmed, whether or not arbitrary periods
1030
d
to
1030
e
of time have passed from completion of the locating program
1031
a
is administrated and determined by the sequencer (step
1103
). If completion has been confirmed (step S
1104
), the locating program
1031
b
is started (step S
1105
). Then, steps S
1106
to S
1110
are similarly performed so that sequential locating of three points is completed.
The above-mentioned conventional location programming apparatus
1004
is arranged in such a manner that each of the Locating programs must be operated to set the locating address, limited speed and acceleration/deceleration time. Moreover, the sequencer or the like is required to manage the programs and sequentially start the programs. Thus, there arises a problem in that long time is required to produce the locating program for each locating point. What is worse, use of the sequencer to administrate the start timing causes the start timing to be affected by scan time of the sequencer. In addition, a program is required for the sequencer.
To solve the above-mentioned problem, the present invention is arranged in such a manner that a sequential operation timing chart is produced to automatically produce a position data table. In accordance with the position data table, locating is performed. Therefore, the necessity of sequentially starting the locating programs can be eliminated and an additional sequencer program is not required. Thus, an object of the present invention is to obtain a location programming apparatus having position information provided as data of sequential position table and enabling preventing a problem of delay of operation start and the like.
When a plurality of axes are located while timings are arranged, for example, when three axes are controlled at an operation timing as shown in
FIG. 198
, a method as shown in flow charts shown in
FIGS. 200 and 201
is available in which the position address of each axis is administrated by a sequencer to arrange the start timing operation the locating program shown in FIG.
199
. Another method may be employed in which timing is arranged in accordance with input from an external sensor or a timer so that the locating program is started to perform the control.
When each axis is located while timing of a plurality of axes is arranged, the conventional location programming apparatus must adjust the positional relationship with the other axes and arrange the start timing. Therefore, the sequencer or the like is required to administrate the positional relationship among the axes so as to perform required control. Therefore, an additional sequencer program is required. Since the administrating sequencer is employed, there arises a problem in that start varies because of scan time of the sequencer.
To solve the above-mentioned problem, an object of the present invention is to provide a location programming apparatus arranged in such a manner that an operation timing chart for each axis is converted into position table data for controlling each cycle of the plurality of the axes; and the position of each axis is controlled in accordance with data. Thus, even if a plurality of axes are controlled, a necessity of producing a sequence for administrating the positional relationship with other axes and adjusting the start timing can be eliminated. Moreover, the problem of delay of start of each axis can be prevented.

150
and location end point (•)
151
are displayed on the two-dimensional coordinates (step S

). Thus, display of the initial window of the two-dimensional graph is ended.
When the number h of the start axes is three or more, an arbitrary combination of the X coordinate number and the Y coordinate number can be selected. When the X coordinate number or the Y coordinate number is changed, the process in step S
216
and ensuing steps shown in
FIG. 15
are performed. Thus, display of the coordinate graph is switched.
FIG. 11
shows an initial window of the coordinate graph which is displayed when, for example, linear control of two axes has been set.
FIG. 16
shows an initial window of a coordinate graph which is displayed when linear control of one axis has been set.

160
has been selected.
The above-mentioned location programming apparatus is structured in such a manner that the operation permissible range of an axis is previously displayed on a graph when a required position is set. When a plurality of axes are interpolation-controlled, the operation at a position with respect to a certain axis can be set. Therefore, the relationship among the axes can easily be understood.
The location programming apparatus according to the present invention is able to generate a locating program by simply setting a locus on a coordinate graph.
Moreover, a locus operation of other axes with respect to a reference axis can be set when a plurality of axes are interpolation-controlled. Thus, the locus operation can easily be recognized.
3. Locating Program for Linear Control by Using Coordinate Graph
The operation for performing locating programming for linear control by using a coordinate graph will now be described with reference to from
FIGS. 17
to
19
.
FIG. 17
shows an example of a window which is displayed when linear control of two axes is performed. Reference numeral
154
represents a pointer for arbitrarily moving a pointer. When the mouse cursor is moved to a required point, the cursor is formed into an arrow cursor facing up, down, right and left as illustrated. When a dragging operation is performed, the cursor is able to freely move in the coordinate-graph making/display area
136
. The point at which the mouse has been released is a decided point. Reference numeral
155
a
represents a cursor bar for moving the point in the direction of the X coordinate and reference numeral
155
b
represents a cursor bar for moving the point in the direction of the Y coordinate. The cursor bars are always displayed for the set point. When the mouse cursor is moved onto the cursor bar, arrow cursors
156
a
and
156
b
permitted to be moved in the directions as illustrated are displayed. When a dragging operation is performed, the point is moved together with the cursor bar. The point at which the mouse dragging has been suspended is the decided position. Reference numeral
157
represents a locus from a location start point
150
to a location end point
151
when linear locating is performed.
The operation which is performed when the point is changed will now be described with reference to a flow chart shown in FIG.
18
. The location start point
150
and the location end point
151
are located at the initial positions in the coordinate-graph making/display area
136
because of the initial window display. When the locating end point is changed (step S
300
), the present location end point (•) is dragged with the mouse to display the movable pointer
154
which is moved to an arbitrary position on the coordinate graph (step S
301
). When the location end point is determined (step S
302
), mouse dragging is suspended (step S
303
). Then, the operation proceeds to step S
304
. When the location end point is not changed in step S
300
, the operation proceeds to step S
304
. When the location start point is changed (step S
304
), the present location start point (×) is dragged by the mouse so that the movable pointer
154
is displayed and moved to an arbitrary position on the coordinate graph (step S
305
). After the location start point has been determined (step S
306
), mouse dragging is suspended (step S
307
). Then, the operation proceeds to step S
308
. When the location start point is not changed in step S
304
, the operation proceeds to step S
308
. When the point is changed, the operation returns to step S
300
. When change has been completed (step S
308
), the setting completion button
160
is selected (step S
309
). Thus, the operation is ended.
The operation which is performed when the point is changed will now be described with reference to a flow chart shown in FIG.
19
. When the location end point
151
is being dragged with the mouse (step S
320
), the location end point (•) is moved to follow the movable pointer
154
. Moreover, also the locus
157
for the linear location and the cursor bars
155
a
and
155
b
are changed (step S
321
). Position information of the X-coordinate axis number nx and that of Y-coordinate axis number ny corresponding to the point (•) on the coordinate graph are calculated so as to be stored in the locating-end-point-position-information storage area
122
of the start axis numbers nx and ny (step S
322
). Thus, the display of the end-point-position display areas
143
a
and
143
b
of the areas
137
a
and
137
b
in which the number of set information on X- and Y-coordinates are stored is updated (step S
323
). The processes in steps S
321
to S
323
are performed until mouse dragging is suspended. When the mouse dragging is suspended, the operation proceeds to step S
325
(step S
324
). If the location end point
151
is not being dragged with the mouse in step S
320
, the operation proceeds to step S
325
.
When the location start point
150
is being dragged with the mouse (step S
325
), the location start point (×) is moved to follow the movable pointer
154
. Moreover, the locus
157
and the cursor bars
155
a
and
155
b
are changed (step S
326
). Position information of X-coordinate axis number nx and that of Y-coordinate axis number ny corresponding to the point (×) on the coordinate graph are calculated so as to be stored in the locating-start-point-position-information storage area
127
of the start axis numbers nx and ny (step S
327
). Thus, display on the start-point-position display areas
142
a
and
142
b
of the areas
137
a
and
137
b
in which the number of set information on X- and Y-coordinates are stored is updated (step S
328
). The processes in steps S
326
to S
328
are performed until mouse dragging is suspended. When mouse dragging is suspended, the operation proceeds to step S
330
(step S
329
). If the location start point
150
is not being dragged with the mouse in step S
325
, the operation proceeds to step S
330
.
When the locating control type is linear location
131
a
, no data is stored in the location-control-type corresponding information storage area
123
of the graphic programming work memory
4
.
The operation returns to step S
320
until the setting completion button
160
is selected. When the setting completion button
160
is selected (step S
330
), location-end-point-position information
122
of the start axis number of coordinate graph output information is outputted as required-position data
2201
of the start axis number of the linear control locating program code. Then, the operation is ended (step S
331
).
The linear control of two axes is performed as described above. When three axes are linear-controlled, two pages of two-dimensional graphs are made by combining the start axis numbers of the X coordinate and Y coordinate. When, for example, first, second and third axes are linear-controlled, two pages are made which include a two-dimensional graph of the first and second axes and that of the first and third axes.
When four axes are linear-interpolated, two or three pages are made to complete the setting operation. When, for example, first, second, third and fourth axes are linear-interpolated, two pages are made which include a two-dimensional graph of the first and second axes and that of the third and fourth axes. As an alternative to this, three pages are made which include a two-dimensional graph of the first and second axes, that of the first and third axes and that of the first and fourth axes.
The above-mentioned location programming apparatus enables required position data to easily be set and changed. Also change of the locus operation caused from the change can simultaneously be confirmed.
The above-mentioned location programming apparatus enables a locating program for the linear control to easily be set and changed by using a locus graph.

500
represents a circular-interpolation passing point which is one instructed passing point during the circular interpolation. When a dragging operation with the mouse is performed, the movable pointer
154
is displayed on the circular-interpolation passing point
500
. Moreover, the circular-interpolation passing point
500
is able to freely moved in the coordinate-graph making/display area
136
. The point at which dragging has been suspended is the decided position. Reference numeral
502
a
and
502
b
represent circular-interpolation-passing-point-position display areas on which X- and Y-coordinates of the circular-interpolation passing point
500
are displayed with figures. Reference numeral
503
represents a locus formed from the location start point
150
to pass through the circular-interpolation passing point
500
so as to reach the location end point
151
, the locus
503
being formed in the circular interpolation.

136
. Then, the left side of the mouse is clicked so that location to the initial position is performed (step S

2701
), the present circular-interpolation passing point (O) is moved to an arbitrary position on the coordinate graph with a movable pointer
154
displayed by dragging the mouse (step S
2702
). When the circular-interpolation passing point has been determined (step S
2703
), mouse dragging is suspended (step S
2704
). Then, the operation proceeds to step S
2705
. When the circular-interpolation passing point is not changed in step S
2701
, the operation proceeds to step S
2705
. When the circular-interpolation passing point is changed, the operation returns to step S
2701
. When the change has been completed (step S
2705
), the setting completion button
160
is selected (step S

.
FIG. 24
shows an example of a window which is displayed when radius-instructed circular interpolation is performed. An alternate long and short dash line and symbols A to G are auxiliary lines and auxiliary symbols for description which are not displayed on the window. Straight line AB is a is a straight line connecting the location start point
150
and the location end point
151
to each other. Straight line CD is an extension of the straight line AB to divide the coordinate-graph making/display area
136
into region E and region F. Circle G is a circle, the diameter of which is the straight line AB. Referring to
FIG. 24
, reference numeral
505
represents a circular-arc-radius-instructing point for instructing the circular interpolation radius with the position of a midpoint of a circular arc which connects the location start point
150
and the location end point
151
to each other. The circular-arc-radius-instructing point
505
is displayed at the initial position of the initial window. When dragging operation with the mouse is performed, the movable pointer
154
is displayed. When the circular-arc-radius-instructing point
505
is moved on a perpendicular bisector of the straight line AB, the radius of the circular arc can be changed. When dragging is suspended, the radius of the circular arc is determined. Reference numeral
506
represents a graph of a radius of a circular arc, the graph connecting the central point of the circular arc and the circular-arc-radius-instructing point
505
to each other so as to graphically indicate the radius of the circular arc. Reference numeral
507
represents a circular-arc-radius display area for displaying the radius of the circular arc with figure.
FIG. 27
shows the location-control-type corresponding information storage area
123
of the graphic programming work memory

The operation for changing setting of the radius-instructed circular arc will now be described with reference to a flow chart shown in FIG.
25
. The location start point
150
and the location end point
151
are located at the initial positions in the coordinate-graph making/display area
136
because of the display of the initial window. When the mouse dragging operation is performed, movement to arbitrary position of each point is permitted. Also the circular-arc-radius-instructing point (O)
505
is disposed on the initial position on the perpendicular bisector of the straight line AB. When setting of the radius-instructed circular arc is changed (step S
2800
), the present circular-arc-radius-instructing point (O)
505
is dragged with the mouse so that the movable pointer
154
is displayed and movement on the perpendicular bisector of the straight line AB is performed (step S
2801
). When setting is not changed in step S
2800
, the operation proceeds to step S
2811
. When the rotational direction of the circular arc is made to be clockwise in step S
2802
, the circular-arc-radius-instructing point (O)
505
is moved to the region E (step S
2803
). When the direction is made to be counterclockwise, the circular-arc-radius-instructing point (O)
505
is moved to the region F (step S
2804
). Then, the operation proceeds to step S
2805
. When the center angle of the circular arc is made to be not smaller than
180
degrees in step S
2805
, the circular-arc-radius-instructing point (O)
505
is moved to the outside of the circle G (step S
2806
). If the center angle is made to be smaller than 180 degrees, the circular-arc-radius-instructing point (O)
505
is moved into the circle G (step S
2807
). The operation proceeds to step S
2808
so that the circular-arc-radius-instructing point (O)
505
is moved in each region to change the radius. When change of the radius has been completed (step S
2809
), mouse dragging is suspended (step S
2810
). If the change is not changed, step S
2808
is repeated. When setting of the radius-instructed circular arc is changed, the operation returns to step S
2800
. When the change has been completed (step S
2811
), the setting completion button
160
is selected (step S
2812
). Thus, the operation is ended.

505
, the circular-arc-radius graph
506
and the circular-arc-radius-figure display area
507
are displayed in step S
2821
. In step S
2822

503
for the circular interpolation is displayed.
When the circular-arc-radius-instructing point (O)
505
is being dragged by the mouse (step S
2823

507
are updated in step S
2827
. In accordance with information in the circular-interpolation-radius, location start point, location end point and circular-interpolation-central-point position information storage areas
550
,

,
122
a
,
122
b
,
551
a
and
551
b
, the locus
503
for the circular interpolation is updated in step S
2828
. The processes in steps S
2824
to S
2828
are performed until mouse dragging is suspended. When mouse dragging has been suspended, the operation proceeds to step S
2830
(step S
2829
). If the circular-arc-radius-instructing point (O)
505
is not being dragged by the mouse in step S
2823
, the operation proceeds to step S
2836
.
When the circular-arc-radius-instructing point (O)
505
is in the region E in step S
2830
, “clockwise” is stored in the passage-information-1-storage area
555
(step S
2831
). When the circular-arc-radius-instructing point (O)
505
is in the region F, “counterclockwise” is stored (step S
2832
). Then, the operation proceeds to step S
2833
. If the circular-arc-radius-instructing point (O)
505
is on the inside of the circle G in step S
2833
, “smaller than 180 degrees” is stored in the passage-information-2-storage area
556
(step S
2834
). When the circular-arc-radius-instructing point (O)
505
is on the circle G or outside the circle G, “not smaller than 180 degrees” is stored (step S
2835
). Then, operation proceeds to step S
2836
.
The operation returns to step S
2823
until the setting completion button
160
is selected. When the setting completion button
160
has been selected (step S
2836
), position in f in the location-end-point-position-information storage areas
122
a
and
122
b
of the start axis numbers stored in the graphic programming work memory

is outputted as required position data
2201
a
and
2201
b
of the start axis numbers of the radius-instructed circular interpolation locating program code (step S
2837
). Then, information in the circular-interpolation radius storage area, passage-information-1-storage area and passage-information-2-storage area
550
,
555
and
556
is outputted as data
2400
,
2401
and
2402
of circular interpolation radius, passage information
1
and passage information
2
(step S
2838
).
The operation for setting and changing the circular-arc-radius-instructing point
505
is performed as described above. Also the location start point
150
and the location end point
151
can arbitrarily be changed by the above-mentioned operation until the setting completion button
160
is selected.
The above-mentioned location programming apparatus enables the locating program for the radius-instructed circular interpolation control to easily be set and changed by using the locus graph.
6. Locating Programming for Central-Point-Instructed Circular Interpolation Using Coordinate Graph
The operation for performing locating programming for the central-point-instructed circular interpolation by using a coordinate graph will now be described with reference to
FIGS. 28
to
31
.
FIG. 28
shows an example of a window which is displayed when central-point-instructed circular interpolation is performed. Reference numeral
510
circular interpolation central point. When mouse dragging is performed, the movable pointer
154
is displayed. Moreover, the circular interpolation central point
510
is able to freely move in the coordinate-graph making/display area
136
. The point at which dragging has been suspended is the decided point. Reference numerals
511
a
and
511
b
represent circular interpolation central-point-position display areas
511
a
and
511
b
in which the X- and Y-coordinates of the circular interpolation central point
510
are displayed with figures. Reference numeral
512
represents a rotational-direction-instructing radius graph for connecting the location start point
150
and the circular interpolation central point
510
to each other. Reference numeral
513
represents an arrow cursor for instructing the rotational direction. When the mouse cursor has been moved onto the circular interpolation central point
510
, an arrow facing opposite to the locus
503
for the circular interpolation is displayed. When dragging in the direction indicated by the arrow is performed, the rotational direction is changed. When the central-point-instructed circular interpolation is performed, the location end point
151
is not always set on a circular arc calculated from the circular interpolation central point
510
and the location start point
150
. Therefore, the locus
503
for the circular interpolation is subjected to error correction by a spiral correction method in such a manner that the locus
503
for the circular interpolation pass through the location end point
151
.
FIG. 31
shows the location-control-type corresponding information storage area
123
of the graphic programming work memory
4
. When locating programming for the central-point-instructed circular interpolation is performed, the location-control-type corresponding information storage area
123
is composed of the circular-interpolation radius
550
, the circular-interpolation-central-point-position-information storage areas
551
a
and
551
b
of the start axis numbers, the passage-information-1-storage area
555
for storing information indicating whether the rotational direction of the circular arc is clockwise or counterclockwise and the circular-interpolation-type-setting-range-information storage area
558
.
The operation for setting and changing the central-point-instructed circular arc will now be described with reference to a flow chart shown in FIG.
29
. The location start point
150
and the location end point
151
are located at the initial positions in the coordinate-graph making/display area
136
because of display of the initial window. Each point can be moved to an arbitrary position when the mouse dragging operation has been performed. To display the circular interpolation central point
510
, the mouse cursor is moved to an arbitrary position in the coordinate-graph making/display area
136
. Then, the left side of the mouse is clicked so that the circular interpolation central point
510
is position at the initial position (step S
2900
). When the circular-interpolation central point is changed (step S
2901
), the present circular-interpolation central point (O) is dragged by the mouse. Thus, the movable pointer
154
is displayed so as to be moved to an arbitrary position on the coordinate graph (step S
2902
). When the position of the circular-interpolation central point has been determined (step S
2903
), mouse dragging is suspended (step S
2904
). Then, the operation proceeds to step S
2905
. When the circular-interpolation central point is not changed in step S
2901
, the operation proceeds to step S
2905
. When the rotational direction is changed (step S
2905
), the mouse pointer is moved onto the rotational-direction-instructing radius graph
512
so that the rotational-direction-instructing radius graph
512
is displayed. Then, mouse dragging is performed in the direction indicated by the arrow so that the rotational direction is changed (step S
2906
). When the rotational direction is not changed in step S
2905
, the operation proceeds to step S
2907
. When the central-point-instructed circular arc is changed, the operation returns to step S
2901
. When the change has been completed (step S
2907
), the setting completion button
160
is selected (step S
2708
). Thus, the operation is ended.
The operation for setting and changing the central-point-instructed circular arc will now be described with reference to a flow chart shown in FIG.
30
. When the left side of the mouse has been clicked on the coordinate-graph making/display area
136
(step S
2910
), the circular interpolation central point (O)
510
is displayed at the present position of the mouse pointer. Moreover, the cursor bars
155
a
and
155
b
corresponding to the point (O) on the coordinate graph are displayed (step S
2911
). Moreover, position information of the X-coordinate axis number nx and Y-coordinate axis number ny corresponding to the point (O) on the coordinate graph is calculated so as to be stored in the circular-interpolation-central-point-position-information storage areas
551
a
and
551
b
of the start axis numbers nx and ny (step S
2912
). Moreover, the initial value of the rotational direction is stored in the passage-information-1-storage area (step S
2912
). Moreover, the circular interpolation central-point-position display areas
511
a
and
511
b
are displayed in the areas
137
a
and
137
b
in which the number of set information on X- and Y-coordinates are stored so that position information is displayed with figures (step S
2913
). In accordance with information in the areas
127
a
,
127
b
,
551
a
and
551
b
for storing information of the positions of the location start point and the circular interpolation central point, the circular interpolation radius is calculated in step S
2914
so as to be stored in the circular-interpolation radius
550
. Moreover, the rotational-direction-instructing radius graph
512
is displayed (step S
2915
). In accordance with information in the areas

1
, the locus
503
for the circular interpolation control is displayed in step S
2916
.
When the circular interpolation central point (O)
510
is being dragged with the mouse (step S
2917
), the circular interpolation central point (O) is moved to follow the movable pointer
154
. Moreover, the cursor bars
155
a
and
155
b
are changed to follow the movable pointer
154
(step S
2918
). Then, position information of the X-coordinate axis number nx and Y-coordinate axis number ny corresponding to the point (O) on the coordinate graph is calculated so as to be stored in the circular-interpolation-central-point-position-information storage areas
551
a
and
551
b
of the start axis numbers nx and ny (step S
2919
). Thus, the displayed figures in the circular-interpolation-passing-point-position display areas

a
and
502
b
of the areas
137
a
and
137
b

2920
). In accordance with information in the areas
127
a
,
127
b
,
551
a
and
551
b
for storing position information of the location start point and the circular interpolation central point, the circular interpolation radius is calculated so as to be stored in the circular-interpolation radius
550
in step S
2921
. Moreover, the rotational-direction-instructing radius graph
512
is updated (step S
2922
). In accordance with information in the areas

, the locus
503
is updated for the circular interpolation in step S
2923
. The processes in steps S
2918
to S
2923
are performed until mouse dragging is suspended. When mouse dragging has been suspended, the operation proceeds to step S
2925
(step S
2924
). When the circular interpolation central point (O)
510
is not being dragged in step S
2917
, the operation proceeds to step S
2925
.
When the rotational-direction-instructing radius graph
512
has been dragged toward the rotational-direction-instructing arrow cursor
513
(step S
2925
), the operation proceeds to step S
2926
. When present information in the passage-information-1-storage area
555
is “clockwise”, “counterclockwise” is stored in the passage-information-1-storage area
555
(step S
2927
). When present information is “counterclockwise”, “clockwise” is stored (step S

The operation for setting and changing the passing point and the passing method will now be described with reference to a flow chart shown in FIG.
38
. When the location start point
150
and the location end point
151
are changed (step S
400
), the operation described to perform the linear control is performed so that changes are performed (step S
401
). When a passing point is added (step S
402
), the mouse cursor is moved onto a locus in a region (a region between the location start point
150
and the location end point
151
in an initial state) to which the passing point is added so that the passing point setting/moving pointer
158
is displayed. Then, the mouse is dragged so as to move the passing point setting/moving pointer
158
to any one of arbitrary upper, lower, right and left position (step S
403
). When the position of the passing point has been determined (step S
404
), mouse dragging is suspended (step S
405
). Then, the operation proceeds to step S
406
. If no passing point is added in step S
402
, the operation proceeds to step S
406
.
When a method of passing between points is changed (step S
406
), the mouse cursor is moved to a locus in a region in which the passing method is changed. Then, the left side is clicked so that selection is performed (step S
407
). Then, a button is selected by the passing-method selection button

, passing-point-instructed circular interpolation
164
b
, radius-instructed circular interpolation
164
c
and the central-point-instructed circular interpolation
164
d
(step S
408
). When the circular interpolation has been selected (step S

), required auxiliary setting (circular arc passing point, the radius, the central point and the like) is performed in accordance with the passing-point-instructed circular interpolation, the radius-instructed circular interpolation and the central-point-instructed circular interpolation (step S
410
). Then, the operation proceeds to step S
411
. If the passing method is not changed in step S
406
, the operation proceeds to step S
411
.
When the position of the set passing point is changed (step S
411
), the passing point (O)
159
p
m
which must be changed is dragged with the mouse so that the movable pointer
154
is displayed which is moved to an arbitrary position on the coordinate graph (step S
412
). When the position of the passing point has been determined (step S
413
), mouse dragging is suspended (step S
414
) and the operation proceeds to step S
415
. If auxiliary setting in the regions across the point, which must be changed, is changed when the position of the passing point is changed (step S
415
), change is performed in accordance with the passing-point-instructed circular interpolation, the radius-instructed circular interpolation and the central-point-instructed circular interpolation (step S
416
). Then, the operation proceeds to step S
417
. If the position of the passing point is not changed in step S
411
, the operation proceeds to step S
417
.
If the passing point and the passing method is set and changed, the operation returns to step S
400
. When all passing points have been set and when passing methods for all regions have been set, the setting completion button
160
is selected (step S
418
). Then, the operation is ended.
The operation for setting and changing the passing point and the passing method will now be described with reference to a flow chart shown in
FIGS. 39
to
44
. The process until the initial window of the coordinate graph is displayed is performed similarly to the above-mentioned coordinate graph. The area
120
for storing the number of set points in the graphic programming work memory
4
is initialized to “1”. Also the locating-start-point-position-information storage area
127
and the locating-end-point-position-information storage area
122
have been initialized.
In a state shown in
FIG. 39
, a passing-method storage area
166
for the region M+1 is initialized to “straight line” (step S
420
). Then, the operation proceeds to step S
421
. When the location end point
151
is being dragged with the mouse (step S
421
), the location end point (•) is moved to follow the movable pointer
154
. Moreover, also the cursor bars
155
a
and
155
b
are changed so that also the locus
162
in the region M+1 is changed by the passing method
166
set for the region M+1 (step S
422
). Position information of X-coordinate axis number nx and that of Y-coordinate axis number ny corresponding to the position of the point (•) on the coordinate graph are calculated so as to be stored in the locating-end-point-position-information storage area
122
of the start axis numbers nx and ny (step S
322
). Moreover, display in the end-point-position display areas
143
a
and
143
b
of the areas
137
a
and
137
b
in which the number of set information on X- and Y-coordinates are stored is updated (step S
323
). The processes in steps S
422
to S
323
are performed until mouse dragging is suspended. When mouse dragging has been suspended, the operation proceeds to step S
424
(step S
423
). If the location end point
151
is not being dragged with the mouse in step S
421
, the operation proceeds to step S
424
.
If the location start point
150
is being dragged with the mouse (step S
424
), the location start point (×) is moved to follow the movable pointer
154
. Also the cursor bars
155
a
and
155
b
are changed (step S
425
). If the passing point P
1
has been set (step S
426
), the locus
162
for the region
1
is changed by the passing method
166
p
1
(step S
427
). If setting is not performed, the locus
162
for the region M+1 (=region
1
) is changed by the passing method
166
(straight line) set for the region M+1 (step S
428
). Position information of the X-coordinate axis number nx and that of the Y-coordinate axis number ny corresponding to the position of the point (×) on the coordinate graph are calculated so as to be stored in the locating-start-point-position-information storage area
127
of the start axis numbers nx and ny (step S
327
). Thus, display on the start-point-position display areas
142
a
and
142
b
of the areas
137
a
and
137
b
in which the number of set information on X- and Y-coordinates are stored is updated (step S
328
). The processes in steps S
425
to S
328
are performed until mouse dragging is suspended. When mouse dragging has been suspended, the operation proceeds to step S
430
(step S
429
). If the location start point
150
is not being dragged with the mouse in step S
424
, the operation proceeds to step S
430
.
When the passing point P
m
159
p
m
is being dragged with the mouse (step S
430
), the passing point (O) is moved to follow the movable pointer
154
. Moreover, also the cursor bars
155
a
and
155
b
are changed (step S
431
). Thus, the locus
162
in the regions m and m+1 is changed by the passing methods
166
p
m
and
166
p
m+1
set for the regions m and m+1 (step S
432
). Position information of the X-coordinate axis number nx and that of the Y-coordinate axis number ny corresponding to the position of the point P
m
(O) on the coordinate graph are calculated so as to be stored in the areas corresponding to the nx and ny axes of the passing point position information storage areas
169
a
m
,
169
b
m
and
169
c
m
of the start axis numbers in the region m (step S
433
). Thus, display of the display areas
161
a
m
and
16
b
m
of the position of the passing point P
m
in the areas
137
a
and
137
b
in which the number of set information on X- and Y-coordinates are stored (step S
434
). The processes in steps S
431
to S
434
are performed until mouse dragging is suspended. When mouse dragging has been suspended, the operation proceeds to step S
436
(step S
423
). If the passing point P
m
is not being dragged with the mouse in step S
430
, the operation proceeds to step S
436
.
When the locus in the region m is being dragged with the pointer for setting/moving the passing point (step S
436
), the process for adding the passing point shown in a flow chart shown in
FIG. 41
is performed (step S
437
). When dragging with the pointer for setting/moving the passing point is not being performed in step S
436
, the operation proceeds to step S
438
.
When the passing method selection button has been selected (step S
438
), the process for setting a passing method shown in a flow chart shown in
FIG. 42
is performed (step S
439
). If the button has not been selected, the operation proceeds to step S
440
.
When auxiliary setting is being changed in the region in which the passing method is the circular interpolation (step S
440
), the processes described in the passing-point-instructed circular interpolation, the radius-instructed circular interpolation and the central-point-instructed circular interpolation are performed (step S
441
).
The operation returns to step S
421
until the setting completion button
160
is selected. When the setting completion button
160
has been selected (step S
442
), locating program information of coordinate graph output information when the locus control has been set is outputted as position data of the linear control locating program code in accordance with a flow chart shown in
FIGS. 43 and 44
. Then, the operation is ended (step S
443
).
The operation for adding a passing point will now be described with reference to a flow chart shown in FIG.
41
. When a locus in a region m is dragged, the position-information storage area for the passing point which is being added is initialized. Position instruction method
165
p
m
for the present region m is stored in the position-instruction-method storage area
165
p
x
as an initial value, “straight line” is stored in the passing-method storage area
166
p
x
as an initial value and information of the dragging position is stored in the passing-point-position-information storage areas
169
a
x
,
169
b
x
and
169
c
x
of the start axis numbers as initial value (step S
450
). Then, the passing point P
x
(O) which is being added is moved to follow the passing point setting/moving pointer
158
. Moreover, the cursor bars
155
a
and
155
b
are displayed so that change is made (step S
451
). Thus, the area between the points P
m−1
and P
x
and that between the points P
x
and P
m
are connected to each other with a linear locus so as to be changed (step S
452
). Moreover, position information of the X-coordinate axis number nx and that of the Y-coordinate axis number ny corresponding to the position of the point P
x
on the coordinate graph are calculated so as to be stored in the areas of the areas
169
a
x
,
169
b
x
, and
169
c
x
for storing position information of a passing point of the start axis number which is being set (step S
453
). Thus, display on the areas
161
a
x
and
161
b
x
for displaying the position of the passing point P
x
in the areas
137
a
and
137
b
in which the number of set information on X- and Y-coordinates are stored is updated (step S
454
). The processes in steps S
451
to S
454
are performed until mouse dragging is suspended. When the mouse dragging has been suspended, the operation proceeds to step S
456
(step S
455
) so that locating program information is updated.
Initially, the number M of passing points is made to be M+1, the value of the area
120
for storing the number of set points is increased by one (step S
456
). Position control information
168
pm
to
168
p
M
of the regions m to M before the point is added is made to be position control information
168
p
m+1
to
168
p
m
of the regions m+1 to M after the point has been added (step S
457
). Then, the passing-method storage area
166
p
m+1
of the region m+1 after the point has been added is initialized to “straight line” (step S
458
). Then, the contents of the area for storing information of the position of the passing point which is being added are stored in the position-control-information storage area
168
p
m
for the region m (step S
459
). Finally, passing point names P
m+1
to P
M+1
are substituted for P
m
to P
M
of the areas
137
a
and
137
b
in which the number of set information on X- and Y-coordinates are stored. Moreover, P
m
is substituted for P
x
(step S
460
). Thus, the process for adding a passing point is ended.
The operation which is performed when the passing method selection button has been selected will now be described with reference to a flow chart shown in FIG.
42
. If no region has been selected, no operation is performed and the process is ended (step S
470
). The passing-method storage area
166
or
166
p
m
of the region m (1≦m≦M+1) indicated with the selected region
163
is updated (step S
471
). When “straight line
164
a
” has been selected (step S
472
), display of the locus in the region m is modified with display of a straight line (step S
473
). If the locus is not the “straight line”, X-coordinate axis number nx and Y-coordinate axis number ny are stored in the areas
170
a
and
170
b
for storing circular interpolation axis numbers
1
and
2
of the area
167
or
167
p
m
for storing passing-method corresponding information for the region m (step S
474
). When auxiliary setting of the circular-arc passing point, radius and central point of the circular arc has been set in accordance with the passing point, radius and central-point instructed circular interpolation (step S
475
), the locus of the circular arc is displayed (step S
476
). Thus, the operation for selecting the passing method is ended.
The operation which is performed when the setting completion button has been selected will now be described with reference to a flow chart shown in
FIGS. 43 and 44
. A value −1(M) obtained by subtracting one from a value of the number
120
of the set points of coordinate graph output information is made to be the number
2607
of passing points of the locus control locating program code (step S
480
). Output is made from area
168
p
m
for storing position control information of the region m of coordinate graph output information to the region m
2608
p
m
of the locus control locating program code is performed for the region
1
to region M. Initially, information of the passing method
166
p
m
is made to be passing method
2602
p
m
(step S
481
). When the passing method is “straight line” (step S
482
), passing-point-position information
169
a
m
,
169
b
m
and
169
c
m
of the start axis numbers are made to be data
2610
a
,
2610
b
and
2610
c
of the start axis numbers of data
2603
p
m
corresponding to the passing method (step S
483
). When the passing method is not straight line, circular interpolation axis numbers
170
a
and
170
b
are made to be circular interpolation axis numbers
2611
a
and
2611
b
. Moreover, information of the axes corresponding to the circular interpolation axis numbers of passing-point-position information
169
a
m
,
169
b
m
and
169
c
m
of the start axis numbers is made to be required position data
2612
a
and
2612
b
of the circular interpolation axis numbers (step S
484
). When the passing method is the “passing-point-instructed circular interpolation” (step S
485
), passing-point-position data
2613
a
and
2613
b
of the circular interpolation axis number is outputted from position information
171
when the method is the passing-point-instructed circular interpolation (step S
486
). When the passing method is the “radius-instructed circular interpolation” (step S
487
), radius
2614
, data
2615
of passage information
1
and data
2616
of passage information
2
are outputted from position information
172
when the interpolation is the radius-instructed circular interpolation (step S
488
). When the passing method is the “central-point-instructed circular interpolation”, central-point-position data
2617
a
and
2617
b
and circular-interpolation-error-permissible range
2618
of the circular interpolation axis numbers are outputted from the position information
173
when the interpolation method is the central-point-instructed circular interpolation (step S
489
).
When the processes in steps
481
to
489
for all of the passing points (1≦m≦M) have been completed (step S
490
), a process for the region M+1 is similarly performed. Information of the passing method
166
is made to be passing method
2602
(step S
491
). When the passing method is the “straight line” (step S
492
), location-end-point-position information
122
a
,
122
b
and
122
c
of the start axis numbers is made to be required position data
2610
a
,
2610
b
and
2610
c
of data
2603
corresponding to the passing method (step S
493
). When the passing method is not the straight line method, circular interpolation axis numbers
170
a
and
170
b
are made to be circular interpolation axis numbers
2611
a
and
2611
b
. Moreover, information of the axes corresponding to circular interpolation axis numbers of location-end-point-position information
122
a
,
122
b
and
122
c
of the start axis numbers is made to be required position data
2612
a
and
2612
b
of the circular interpolation axis numbers (step S
494
). Moreover, the processes which are the same as those in steps S
485
to S
489
are performed, and then the operation which is performed when setting has been completed is ended.
The above-mentioned location programming apparatus enables the passing point to easily be set, changed and added when a plurality of passing points are instructed and the locus control is set. Moreover, the process of the change of the locus operation occurring due to change in the position of the passing point can simultaneously be confirmed.
The above-mentioned location programming apparatus enables a locating program for use when the locus control is performed to easily be set and changed by using a locus graph.
8. Locating Programming for Setting Position Instruction Method by Using Coordinate Graph
The operation for performing locating programming by setting a position instruction method by using a coordinate graph will now be described with reference to
FIGS. 45
to
49
.
FIG. 45
shows an example of a window for performing programming of linear interpolation of two axes by using an absolute coordinate graph in such a manner that the locating position is instructed with an absolute position.
FIG. 46
shows an example of a window for performing programming of linear interpolation of two axes by using a relative coordinate graph in such a manner that the locating position is instructed with a relative amount of movement from the locating start point. Referring to
FIGS. 45 and 46
, reference numeral
180
represents a position-instruction-method selection button for selecting either absolute-position instruction
180
a
or relative-movement-amount instruction
180
b
. When the initial window of the coordinate graph is displayed, an absolute position instruction is displayed. Reference numeral
157
represents a locus when the absolute position is instructed and
182
represents a locus when the relative amount of movement is instructed. A solid line and an alternate long and short dash line are used to display the corresponding instruction. Reference numeral
181
represents a reference point for a relative coordinate.
FIG. 47
shows the structure of a position-information storage area for each point of coordinate graph output information, the area being composed of an absolute-position-information storage area
183
and a relative-movement-amount storage area
184
. Foregoing information corresponds to each point position information in the locating-end-point-position-information storage area
122
and the location-control-type corresponding information storage area
123
of the start axis numbers shown in FIG.
13
and the locating-start-point-position-information storage area
127
of the start axis number shown in FIG.
14
.
The operation which is performed when the position-instruction-method selection button has been selected will now be described with reference to a flow chart shown in FIG.
48
. When the locating control type is linear control locating, passing-point-instructed circular interpolation, the radius-instructed circular interpolation or the central-point-instructed circular interpolation, “absolute position instruction” is stored in the position-location-method storage area
121
of the graphic programming work memory
4
(step S
500
). In accordance with the description in the coordinate graph, a an initial window of the coordinate graph is displayed (step S
501
).
When the relative-movement-amount instruction
180
b
is selected with the position-instruction-method selection button
180
and thus the position instruction method has been changed from the “absolute position instruction” to the “relative movement amount instruction” (step S
502
), “relative movement amount instruction” is stored in the position-location-method storage area
121
(step S
503
). Moreover, the reference point
181
is displayed at the position of the present location start point (×)
150
so that switch to the relative coordinate graph is performed (step S
504
). The relative movement amount is calculated from absolute position information of each point in accordance with equations
500
,
501
and
502
so as to be stored in the relative-movement-amount storage area
184
portion of the locating-start-point-position-information storage areas

,
127

and

and the location-control-type corresponding information storage area

in which the number of set information on X- and Y-coordinates are stored are updated to relative movement amounts in accordance with relative movement amount position information of the points (step S
506
). Moreover, a locus of the location is again displayed with an alternate long and short dash line (step S
507
).
The operation for changing a point in a relative coordinate graph will now be described with reference to a flow chart shown in
FIG. 49
(step S
508
).
When a process for completing setting is not performed when the point is changed, the operation returns to step S
502
. When setting has been completed (step S
509
), the position instruction method
121
of the coordinate graph output information is outputted as a position instruction method
2105
of the locating program code (step S
510
).
If the position instruction method which is the “relative movement amount instruction” is not changed in step S
502
, the operation proceeds to step S
508
(step S
511
). Thus, the absolute-position instruction
180
a
is selected so that the position instruction method is changed from the “relative movement amount instruction” to the “absolute position instruction” (step S
512
). Thus, the “absolute position instruction” is stored in the position-location-method storage area
121
(step S
513
). Then, display of the reference point
181
is deleted and switch to the absolute coordinate graph is performed (step S
514
). In accordance with equations
503
,
504
and
505
, the absolute-position-information storage area
183
portion of the location-start-point-position-information storage areas

,

and
122

of the start axis numbers and the location-control-type corresponding information storage area
123
is initialized (step S
515
). Thus, the locus of locating is again displayed with a solid line (step S
516
).

The operation for changing a point with an absolute coordinate graph is performed in accordance with the linear control, the passing-point-instructed circular interpolation, the radius-instructed circular interpolation and the central-point-instructed circular interpolation (step S
517
). Then, the operation proceeds to step S
509
.
If the instructed position instruction method “absolute position instruction” is not changed in step S
512
, the operation proceeds to step S
517
.
If the position instruction method is the absolute position instruction in step S
517
, an operation is performed in accordance with a flow chart shown in
FIG. 19
when linear control is performed. Position information of the location end point and that of the location start point calculated in steps S
322
and
327
are stored in the absolute-position-information storage area
183
. In step S
331
required position data of the locating program code is outputted in accordance with absolute-position-information storage area
183
of the locating-end-point-position-information storage area
122
of the start axis number. Also the passing-point-instructed circular interpolation, the radius-instructed circular interpolation and the central-point-instructed circular interpolation are performed similarly.
The operation for changing a point with a relative coordinate graph will now be described with reference to a flow chart shown in FIG.
49
. The same operations in the flow chart as those of the point changing operation with the absolute coordinate graph in the flow chart shown in
FIG. 19
are given the same step numbers and operated as described in the linear control.
In step S
520
which is the operation during dragging of a location end point with the mouse, the relative among from point (•) to the location start point (×) on the coordinate graph is calculated as position information of X-coordinate axis number nx and that of Y-coordinate axis number ny so as to be stored in the relative-movement-amount storage area
184
of the locating-end-point-position-information storage area
122
of the start axis numbers nx and ny (step S
520
). Moreover, information of the relative movement amount is displayed in the end-point-position display areas
143
a
and
143
b
of the areas
137
a
and
137
b
in which the number of set information on X- and Y-coordinates are stored (step S
521
). Then, the operation proceeds to step S
324
.
After step S
326
which is the operation during dragging of the location start point with the mouse has been performed, also the reference point
181
for the relative coordinate is moved to following location start point (×)(step S
522
). The moving location start point (×) is always made to be a reference point (O) to calculate a relative amount to the location end point (•) on the coordinate graph. A result is, as position information of the X-coordinate axis number nx and Y-coordinate axis ny, stored in the relative-movement-amount storage area
184
of the end-point-position-information storage area
122
of the start axis numbers nx and ny (step S
523
). Finally, information of the relative movement amount is displayed on the end-point-position display areas
143
a
and
143
b
of the areas
137
a
and
137
b
in which the number of set information on X- and Y-coordinates are stored (step S
524
). Then, the operation proceeds to step S
329
.
When the setting completion button
160
has been selected (step S
330
), required position data of the locating program code is outputted in accordance with relative-movement-amount information
184
of location-end-point-position information
122
of the start axis number (step S
525
).
The processes in the other steps are the same as those when a point is changed by using the absolute coordinate graph.
FIG. 49
shows the linear control. When circular interpolation is performed, a process similar to that for the location end point is added for the circular interpolation auxiliary point.
The above-mentioned location programming apparatus enables the method of instructing a position to immediately be understood. If a method of instructing the position has been changed, position information can be maintained and the same is converted into position information corresponding to the position instruction method.
The above-mentioned location programming apparatus enables a locating program to easily be set and changed by using a locus graph. Thus, a position instruction method can easily be recognized from a locus graph.
9. Locating Programming for Locus Control for Setting Position Instruction Method by Using Coordinate Graph
The operation for performing locating programming of a locus control in such a manner that a position instruction method is set by using a coordinate graph will now be described with reference to
FIGS. 50
to
60
.
FIG. 50
shows an example of a window for performing programming for locus-controlling two axes by using a coordinate graph in a case where a region in which the passing point and location end point are instructed with an absolute position and a region in which instruction is performed in accordance with a relative movement amount from the previous point are mixed. Referring to the drawings, reference numeral
180
represents a position-instruction-method selection button
180
for each region. Either of the absolute-position instruction
180
a
or the relative-movement-amount instruction
180
b
is selected for a selected region
163
so that a position instruction method is set and changed. When the initial window of the coordinate graph is displayed, the region M+1 (=region

represents a locus in an absolute position instruction region and
185
represents a locus in a relative movement amount instruction region which are displayed by different types of lines which are a solid line and an alternate lone and short dash line. Both of absolute position information and relative movement amount information are displayed on point position display areas

The operation for setting and changing the position instruction method for each region will now be described with reference to a flow chart shown in FIG.
52
. Referring to
FIG. 52
, the same portions as those in the flow chart shown in
FIG. 38
of the operation for setting and changing the passing point and the passing method by the locus control method are given the same step numbers and they are performed similarly to the locus control. When the position instruction method is changed in each region (step S
550
), the mouse cursor is moved onto the locus in the region in which the position instruction method is changed. Then, right side is clicked to perform selection (step S
551
). Then, a button corresponding to required method is selected from the absolute-position instruction
180
a
and the relative-movement-amount instruction
180
b
of the position-instruction-method selection button
180
(step S
552
). When all of the passing points have been set and the passing method and the position instruction method have been completed for all of the regions (step S
553
), the setting completion button
160
is selected (step S
418
). Then, the operation is ended.
The operation for setting position instruction method for each region in the locus control and performing programming will now be described with reference to a flow chart shown in
FIGS. 53
to
60
.
FIGS. 53 and 54
shows a flow chart showing the overall operation. In
FIGS. 53 and 54
, the same portions as those in the flow chart shown in
FIGS. 39 and 40
of the operation for setting and changing the passing point and the passing method are given the same step numbers and they are operated as described in the locus control. When the locating control type is the locus control, “absolute position instruction” is stored in the position-instruction-method storage area
165
of the graphic programming work memory
4
for the region M+1 (step S
560
). Thus, an initial window of the coordinate graph is displayed in accordance with the description of the coordinate graph (step S
561
).
If the position instruction method for each region is the absolute position instruction or the relative movement amount instruction, absolute position information of the subject point and the relative movement amount of regions across the moving point are always updated and administrated when the location start point and the location end point are moved and a passing point is added and moved. When the location end point (•) is being dragged, the absolute positions of the X-coordinate axis number nx and the Y-coordinate axis number ny corresponding to the position of the point (•) and a relative amount from the previous point are calculated so as to be stored in the absolute-position-information storage area
183
and the relative-movement-amount storage area
184
of end-point-position information
122
of the start axis numbers nx and ny (step S
562
). Then, both of the absolute position and the relative movement amount are displayed in the end-point-position display areas
143
a
and
143
b
of the areas
137
a
and
137
b
in which the number of set information on X- and Y-coordinates are stored (step S
563
).
When the location start point (×) is being dragged, the operation will now be described with reference to a flow chart shown in
FIG. 55
(step S
564
). Initially, the absolute positions of the start axis numbers nx and ny corresponding to the point (×) are calculated so as to be stored in the absolute-position-information storage area
183
of the locating-start-point-position-information storage area
127
of the start axis numbers nx and ny (step S
580
). Then, display of the absolute position in the start-point-position display areas
142
a
and
142
b
of the areas
137
a
and
137
b
in which the number of set information on X- and Y-coordinates are stored is updated (step S
581
). If the passing point P
1
has been set (step S
582
), the relative amounts of the nx and ny axes from the point (×) to the point P
1
are calculated so as to be stored in the relative-movement-amount storage area
184
of the corresponding nx and ny areas of the passing-point-position information
169
a
1
,
169
b
1
and
169
c
1
of the start axis numbers in the region
1
(step S
583
). Thus, display of the relative movement amount in the areas
161
a
1
and
161
b
1
for displaying the number P
1
of the passing points in the areas
137
a
and
137
b
in which the number of set information on X- and Y-coordinates are stored is updated (step S
584
). If the passing point P
1
has not been set in step S
582
, the relative amounts of the nx and ny axes from the point (×) to the location end point (•) are calculated so as to be stored in the area for storing relative amount information
184
of the end-point-position information
122
of the start axis number (step S
585
). Thus, display of the relative movement amount in the end-point-position display areas
143
a
and
143
b
of the areas
137
a
and
137
b
in which the number of set information on X- and Y-coordinates are stored is updated (step S
586
).
When the passing point P
m
(O) is being dragged, the description will be made in accordance with a flow chart shown in
FIG. 56
(step S
565
). Initially, the absolute positions of the X-coordinate axis number nx and Y-coordinate axis number ny corresponding to the point (O) and a relative amount from the previous point are calculated so as to be stored in the absolute-position-information storage area
183
and the relative-movement-amount storage area
184
of the corresponding axes nx and ny of the passing-point-position information
169
a
m
,
169
b
m
and
169
c
m
of the start axis numbers nx and ny in the region m (step S
590
). Thus, display of both of the absolute positions and relative movement amounts in the areas
161
a
m
and
161
b
m
for displaying the number P
m
of passing points of the areas
137
a
and
137
b
in which the number of set information on X- and Y-coordinates are stored is updated (step S
591
). If the relationship that passing point P
m
=final passing point P
M
is not satisfied (step S
592
), a relative amount of the nx and ny axes from the point P
m
(O) to P
m+1
calculated so as to be stored in the area for storing relative-movement-amount information
184
of the corresponding start axis numbers nx and ny of passing point information
169
a
m
,
169
b
m
and
169
c
m
of the start axis number in the region m+1 (step S

m+1
and

m+1
for displaying the number P
m+1
of the passing points of the areas
137
a
and
137
b
in which the number of set information on X- and Y-coordinates are stored is updated (step S
594
). If passing point P
m
=final passing point P
M
in step S
592
, relative amounts of the nx and ny axes from the point P
m
(O) to the location end point (•) are calculated so as to be stored in the relative-movement-amount storage area
184
of location end point position information
122
(step S
595
). Thus, display of relative movement amounts in the end-point-position display areas
143
a
and
143
b
of the areas
137
a
and
137
b
in which the number of set information on X- and Y-coordinates are stored is updated (step S
596
).
The operation which is performed when the locus in the region m is being dragged with the passing-point setting and moving pointer will now be described with reference to a flow chart shown in
FIG. 57
(step S
566
). The same portions as those in the flow chart shown in
FIG. 41
of the operation which is performed when a passing point is added and set are given the same step numbers and they are operate similarly to those in the locus control. Initially, the areas for storing position information of the passing point which is being added are initialized in such a manner that initial value are stored in the absolute-position-information storage area
183
and the relative-movement-amount storage area
184
for information of the passing point of the start axis number which is being set (step S
600
). When mouse dragging is being performed, the absolute positions of the X-coordinate axis number nx and Y-coordinate axis number ny corresponding to the position of the point Px (O) and a relative amount from the previous point are calculated so as to be stored in the absolute-position-information storage area
183
and the relative-movement-amount storage area
184
of the corresponding axes nx and ny of information
169
a
x
,
169
b
x
and
169
c
x
of the position of the passing point of the start axis number which is being set (step S

). Thus, display of both of the absolute position and the relative movement amount of the areas

and
161
b
x
for displaying the number P
x
of passing points in the areas
137
a
and
137
b
in which the number of set information on X- and Y-coordinates are stored is updated (step S
602
). Then, relative amounts of nx and ny axes from the point P
x
(O) to P
m
are calculated so as to be stored in the areas for the corresponding axes nx and ny of information
186
a
,
186
b
and
186
c
of the relative movement amount between P
x
and P
m
of the start axis numbers (step S
603
). Thus, display of the relative movement amount in the areas
161
a

and
161
b
m
for displaying the number P
m
of passing points in the areas
137
a
and
137
b
in which the number of set information on X- and Y-coordinates are stored is updated (step S
604
). When dragging is suspended, stored information
186
a
,
186
b
and
186
c
of the relative movement amount between P
x
and P
m
of the start axis number for nx and ny axes is stored in the relative-movement-amount storage area
184
for the passing point position information
169

m+1
,
169

m+1
and
169
c
m+1
of the start axis number in the region m+1 (step S

).
When the position-instruction-method selection button
180
has been selected (step S
567
), an operation is performed to follow a flow chart shown in
FIG. 58
(step S
568
). If selection of a region is not performed, no operation is performed and the process is ended (step S
610
). The position-instruction-method storage area
165
or
165
p
m
in the region m (1≦m≦M+1) indicated with a selected region
163
is updated (step S
611
). If the “absolute-position instruction
180
a
” has been selected (step S
612
), the locus in the region m is modified with a solid line. If “instruction
180
b
of relative movement amount” has been selected, the locus in the region m is modified with an alternate long and short dash line (step S
614
). When the locus is changed by moving the point, the type of the line corresponding to the method of instructing the position in the corresponding region is employed.
When circular interpolation auxiliary setting has been changed in step S
441
, a relative amount is calculated from information of the absolute position of the auxiliary set point (circular interpolation passing point or the circular interpolation central point) for the circular interpolation and information of the absolute position of the circular interpolation start point so as to be stored in the relative-movement-amount storage area
184
for position information of the corresponding point (step S
569
).
When the setting completion button has been selected, an operation following a flow chart shown in
FIGS. 59 and 60
is performed (step S
570
). The same portions as those in the flow chart shown in
FIG. 43 and 44
which show the operation which is performed when setting of the locus control has been performed are given the same step numbers and they are performed similarly to those in the locus control. In steps S
481
to S
490
for outputting locating program code for the regions
1
to M, information of the position instruction method
165
pm
is made to be position instruction method
2601
pm
(step S
630
). In a region in which the position instruction method is the “absolute position instruction”, absolute position information
183
is made to be required position data
2610
of the start axis number, required position data
2612
of the circular interpolation axis number, passing-point-position data
2613
of the circular interpolation axis number and central-point position data
2617
of the circular interpolation axis number. In the region of the “relative movement amount”, relative movement amount information
184
is made to be the same (steps S
631
, S
632
, S
633
and S
634
).
Also in steps S
491
to S
634
for outputting the locating program code for the region M+1, information of position instruction method
165
is made to be position instruction method
2601
(step S
635
). If the position instruction method is the “absolute position instruction”, location end point position information, circular interpolation passing point position information and circular interpolation central-point position information of the start axis are absolute position information
183
. When the position instruction method is the “relative movement amount instruction”, the relative movement amount information
184
is made to be required position data
2610
of the start axis number, required position data
2612
of the circular interpolation axis number, data
2613
of the passing point data of the circular interpolation axis number and central-point position data
2617
of the circular interpolation axis number (steps S
636
, S
637
, S
633
and S
634
).
The above-mentioned location programming apparatus enables the position instruction method between passing points to quickly be recognized when a plurality of passing points are instructed and a locus control is set. Moreover, even if the position instruction method between the passing points is changed, a necessity of again setting position data can be eliminated.
The above-mentioned location programming apparatus enables the locating program for the locus control to easily be set and changed by using a locus graph. Thus, the position instruction method between passing points can easily be understood from the locus graph.
Moreover, the absolute position and the relative position between the passing points for the locus control can easily be understood.
10. Setting and Change of Operation Permissible Range of Subject Which Must be Controlled By using Coordinate Graph
The operation for setting and changing the operation permissible range for a subject which must be controlled by using a coordinate graph will now be described with reference to
FIGS. 61
to
63
.
FIG. 61
shows an example of a programming window using a coordinate graph. An operation permissible range for a subject which must be controlled is, as upper and lower stroke limit lines
152
a
and
153
a
of the X coordinate axis number and upper and lower stroke limit lines
152
b
and
153
b
of the Y coordinate axis number, read and displayed in such a manner that the upper and lower stroke limits
1705
and
1706
of the axis-parameter memory
1700
are read and displayed to the upper and lower stroke limit storage areas
112
and
113
of the graphic programming work memory
4
. The locating points which are set on the coordinate graph and the locus can easily be recognized. Reference numeral
187
represents a stroke-limit-range changing pointer. When the mouse cursor is moved onto the X coordinate side stroke limit line, the stroke-limit-range changing pointer
187
is formed into an arrow cursor facing right and left. When the mouse cursor is moved onto the Y coordinate side stroke limit line, the stroke-limit-range changing pointer
187
is formed into an arrow cursor facing up and down. The stroke-limit-range changing pointer
187
can be moved into directions indicated by the arrows when a dragging operation has been performed. A position at which the mouse has been released is a decided position.
The operation for changing the stroke limit range will now be described with reference to a flow chart shown in FIG.
62
. When an upper X coordinate stroke limit is changed (step S
650
), the upper X coordinate stroke limit line which is being displayed is dragged with the mouse so that the stroke-limit-range changing pointer
187
is displayed so as to be moved on the coordinate graph to the right or left (step S
651
). When the position has been determined (step S
652
), mouse dragging is suspended (step S
653
). When a lower X coordinate stroke limit is changed (step S
654
), the lower X coordinate stroke limit line which is being displayed is dragged with the mouse so that the stroke-limit-range changing pointer
187
is displayed so as to be moved on the coordinate graph to the right or left (step S
655
). When the position has been determined (step S
656
), mouse dragging is suspended (step S
657
).
When the upper Y coordinate stroke limit is changed in the case where the coordinate graph is a two-dimensional graph (step S
658
), the upper Y coordinate stroke limit line which is being displayed is dragged with the mouse so that the stroke-limit-range changing pointer
187
is displayed which is moved in the vertical direction on the coordinate graph (step S
659
). When the position has been determined (step S
660
), mouse dragging is suspended (step S
661
). When the lower Y coordinate stroke limit is changed (step S
662
), the lower Y coordinate stroke limit line which is being displayed is determined by the mouse so that the stroke-limit-range changing pointer
187
is displayed which is moved in the vertical direction (step S
663
). When the position has been determined (step S
664
), mouse dragging is suspended (step S
665
).
When the stroke limit range is changed, the operation returns to step S
650
. When change has been completed (step S
666
), the setting completion button
160
is selected (step S
667
). Thus, the operation is ended.
The operation for changing the stroke limit range will now be described with reference to a flow chart shown in FIG.
63
. When the line upper X-coordinate stroke lime line
152
a
is being dragged with the mouse (step S
670
), the upper X-coordinate stroke lime line
152
a
is moved to follow the stroke-limit-range changing pointer
187
(step S
671
). Then, position information of the X-coordinate axis number nx corresponding to the line position on the coordinate graph is calculated so as to be stored in the upper stroke limit storage area
112
of the X-coordinate axis number nx (step S
672
). Moreover, the upper stroke limit display area
140
a
in the X-coordinate-setting-information value display area
137
a
is updated (step S
673
). The processes in steps S
671
to S
673
are performed until mouse dragging is suspended. When mouse dragging has been suspended, the operation proceeds to step S
675
(step S
674
). When the upper X-coordinate stroke lime line
152
a
is not being dragged with the mouse in step S
670
, the operation proceeds to step S
675
.
When the lower X-coordinate stroke limit line
153
a
is being dragged with the mouse (step S
675
), the lower X-coordinate stroke limit line
153
a
is moved to follow the stroke-limit-range changing pointer
187
(step S
676
), the lower X-coordinate stroke limit line
153
a
is moved to follow the stroke-limit-range changing pointer
187
(step S
676
). Then, position information of the X-coordinate axis number nx corresponding to the line position on the coordinate graph is calculated so as to be stored in the lower stroke limit storage area
113
of the X-coordinate axis number nx (step S
677
). Moreover, the lower stroke limit display area
141
a
of the X-coordinate-setting-information value display area
137
a
is updated (step S
678
). The processes in steps S
676
to S
678
are performed until mouse dragging is suspended. When mouse dragging is suspended, the operation proceeds to step S
680
(step S
679
). When the lower X-coordinate stroke limit line
153
a
is not being dragged with the mouse in step S
675
, the operation proceeds to step S
680
.
When the upper Y-coordinate stroke limit line
152
b
is being dragged with the mouse (step S
680
), the upper Y-coordinate stroke limit line
152
b
is moved to follow the stroke-limit-range changing pointer
187
(step S
681
). Then, position information of Y-coordinate axis number ny corresponding to the line position on the coordinate graph is calculated so as to be stored in the upper stroke limit storage area
112
of the Y-coordinate axis number ny (step S
682
). Moreover, the upper stroke limit display area
140
b
of the set Y-coordinate information value display area
137
b
is updated (step S
683
). The processes in steps S
681
to S
683
are performed until mouse dragging is suspended. When mouse dragging has been suspended, the operation proceeds to step S
685
(step S
684
). If the upper Y-coordinate stroke limit line
152
b
is not being dragged in step S
680
, the operation proceeds to step S
685
.
When the lower Y-coordinate stroke limit
153
b
is being dragged with the mouse (step S
685
), the lower Y-coordinate stroke limit
153
b
is moved to follow the stroke-limit-range changing pointer
187
(step S
686
). Position information of the Y-coordinate axis number ny corresponding to the line position on the coordinate graph is calculated so as to be stored in the lower stroke limit storage area
113
of the Y-coordinate axis number ny (step S
687
). Moreover, the lower stroke limit display area
141
b
of the set Y-coordinate information value display area
137
b
is updated (step S
688
). The processes in steps S
686
to S
688
are performed until mouse dragging is suspended. When mouse dragging has been suspended, the operation proceeds to step S
690
(step S
689
). If the lower Y-coordinate stroke limit
153
b
is not being dragged with the mouse in step S
685
, the operation proceeds to step S
690
.
The operation returns to step S
670
until the setting completion button
160
is selected. When the setting completion button
160
has been selected (step S
690
), the contents of the areas for storing the upper and lower stroke limits
112
and
113
of the start axis number are, as the locating control parameters, stored in the axis areas of the axis-parameter memory
1700
for storing the upper stroke limit
1705
and the lower stroke limit
1706
(step S
691
). Then, the operation is ended.
The above-mentioned location programming apparatus enables the stroke range for the corresponding axis to easily be confirmed and changed when position data is set.
The above-mentioned location programming apparatus enables the operation permissible range of the subject which must be controlled to easily be set and changed on a locating program window.
When locating programming is performed, the relationship among the points which must be set, the locus and the operation permissible range of the subject which must be controlled can always easily be recognized.
An error that “start cannot be performed because the instructed position does not satisfy the stroke limit range” which is detected by the controller when the program is started can be prevented when locating program is performed.
An error that “operation cannot be performed because an intermediate passage for the location does not satisfy the stroke limit range” which is detected by the controller when the program is started can previously be prevented when programming is performed.

The operation for performing locating programming by using a speed graph will now be described with reference to
FIGS. 64
to
71
.
FIG. 64

(step S
1200
),
1
is stored in the acceleration/deceleration parameter number storage area
230
of the graphic programming work memory
4
(step S
1201
). Then, data of acceleration/deceleration control parameter number

1800
so as to be stored in the speed-control-unit storage area
231
, the limit-speed storage area

238
of the locating-program-speed-information storage area
221
is initialized so that the region-instructed-speed storage area
239
is initialized in a quantity corresponding to the number of points set in the area
120
for storing the number of set points of coordinate graph output information (step S
1203
).
Then, display on the window is performed in accordance with information above. When the set number
82
of start axes is two or more (step S
1204
), any one of [mm/min], [inch/min], [degree/min] and [PLS/sec] is displayed on the speed-control-unit display area
213
in accordance with information in the speed-control-unit storage area
231
(step S
1205
). Then, the operation proceeds to step S
1206
. If the number
82
of the start axes is one in step S
1204
, any one of [mm/min], [inch/min], [degree/min] and [PLS/sec] is displayed on the speed-control-unit display area
213
in accordance with information in the position-control-unit reading area
111
of the start axis number (step S
1213
). Then, the operation proceeds to step S
1206
. In accordance with information in the limit-speed storage area
232
, figures are displayed on the limited speed display area
216
of the speed-information-value display area
203
. Moreover, line display
206
is performed on the speed graph (step S
1206
).
In accordance with information in the acceleration-time storage area
233
, the deceleration-time storage area
234
and the rapid-stop-deceleration-time storage area
235
, display on the acceleration time
207
,and the deceleration time
208
of the display area
202
and the rapid stop deceleration time display area
209
is performed. Each of set time is displayed with arrows
248
,
246
and
245
. Then, the acceleration time pointer
210
, the deceleration time pointer
211
and the rapid stop deceleration time pointer
212
are displayed on the speed graph. Moreover, the inclination
242
of the acceleration pattern, the inclination
243
of the deceleration pattern and the inclination
244
of the rapid stop deceleration pattern are displayed (step S
1207
). In accordance with information in the acceleration/deceleration pattern type storage area
236
, a corresponding acceleration/deceleration pattern selection button
217
is displayed inversely. If S-figure acceleration/deceleration is set, the S-figure ratio is displayed on a S-figure ratio display area
218
(step S
1208
). Information in the area
120
for storing the number of set points is displayed on the set-region-number display area
219
(step S
1209
).
In accordance with information in the speed-instruction-method storage area
238
, the corresponding speed-instruction-method selection button
201
is inverted (step S

). In accordance with information in the region-instructed-speed storage area
239
, figures are displayed on the instructed speed figure display area
215
of the speed-information-value display area
203
. Line display
205
is performed on the speed graph (step S
1211
). In accordance with information in the area
120
for storing the number of set points and region-instructed-speed storage area
239
, the speed pattern
214
is displayed on the speed graph. The speed changing pointers
225
a
and
225
b
are displayed at the start point of a region in which the instructed speed can be set (step S
1212
). Thus, display of the initial window of the speed graph is ended.
The operation for selecting and changing the speed instruction method and the speed control unit and setting and changing the speed pattern by using a speed graph will now be described with reference to
FIGS. 69
to
71
.
FIG. 69
shows an example of a locating programming window by using a speed graph when the speed instruction method, the speed control unit and the instructed speed are set and changed. Reference numeral
240
represents a speed movement pointer for vertically moving the speed line. When the mouse cursor is moved onto a speed line required to be changed, the pointer is formed into an arrow cursor facing up and down as illustrated. When a dragging operation is performed, the pointer is able to move vertically in the speed-graph making and displaying area
204
. A position at which mouse dragging has been suspended is the set speed. Reference numeral
249
represents a speed-control-unit selection button. When the speed-control-unit selection button is clicked, a speed-control-unit selection window
241
is opened. Thus, speed units which can be selected are displayed in accordance with information in the position-control-unit reading area
111
of the start axis number. When an instructed unit is clicked, selection is performed.
An example of the operation will now be described with reference to a flow chart shown in FIG.
70
. If the number
82
of the start axes is not smaller than two and the locating control type
81
is the linear locating, the speed instruction method is initialized to “synthesized speed”. When the speed instruction method is changed (step S
1220
), a synthesized-speed instruction button
201
a
, a reference-axis-speed instruction button
201
b
and a major-axis-speed instruction button
201
c
of the speed-instruction-method selection button
201
are operated so that selection is performed (step S
1221
). If the speed instruction method is not changed in step S
1220
, the operation proceeds to step S
1222
. If the speed control unit is changed in a case where the number
82
of start axes is not smaller than two (step S
1222
), the speed-control-unit selection button
249
is clicked by the mouse so that the speed-control-unit selection window
241
is displayed (step S
1223
). When clicking with the mouse is performed, a unit is selected (step S
1224
). If the speed control unit is not changed in step S
1222
, the operation proceeds to step S
1225
.
When the speed pattern
214
is changed (step S
1225
), the mouse cursor is moved onto the speed pattern
214
for the region intended to be changed. Then, mouse dragging is performed so that the speed movement pointer
240
is displayed which is arbitrarily moved in the vertical direction on the speed graph (step S
1226
). After the instructed speed has been determined (step S
1228
), mouse dragging is suspended (step S
1229
). Then, the operation proceeds to step S
1230
. When the speed pattern is not changed in step S
1225
, the operation proceeds to step S
1230
.
When all items for the speed graph have been set (step S
1230
), the setting completion button
160
is selected (step S
1231
) to complete the operation.
The operation for selecting and changing the speed instruction method and the speed control unit and setting and changing the speed pattern will now be described with reference to a flow chart shown in FIG.
71
. When the speed-instruction-method selection button
201
is clicked by the mouse (step S
1240
) and the number
82
of start axes is not smaller than two and the locating control type storage area
81
is “linear locating” (step S
1241
), information of the selected speed instruction method is stored in the speed-instruction-method storage area
238
(step S
1242
). Moreover, the corresponding buttons
201
a
,
201
b
and
201
c
are inversely displayed (step S
1243
). If the speed-selection-method selection button is not selected in step S
1240
and if locating is not linear locating of two or more axes in step S
1241
, the operation proceeds to step S
1244
.
When the speed control unit selection window is clicked with the mouse (step S
1244
) and the number
82
of start axes is not smaller than two (step S
1245
), the information of the selected speed control unit is stored in the speed-control-unit storage area
231
(step S
1246
) so that display on the speed-control-unit display area
213
is updated (step S
1247
). If the speed control unit window is not clicked with the mouse in step S
1244
, the operation proceeds to step S
1248
in a case where the number of start axis is one in step S
1245
.
If the speed pattern
214
is being dragged with the mouse (step S
1248
), the instructed speed line
205
in the corresponding region is moved to follow the speed movement pointer
240
and also the speed pattern
214
is changed (step S
1249
). Thus, information of the speed corresponding to the position of the instructed speed line
205
in the corresponding region on the speed graph is calculated so as to be stored in the region-instructed-speed storage area
239
in the corresponding region (step S
1250
). If the instructed speed in the corresponding region is different from the instructed speed (step S
1251
), region instructed speed display areas
215
a
and
215
b
of the speed-information-value display area
203
are added and displayed with figures (step S
1252
). If the instructed speed in the corresponding region is the same as that in the previous region in step S
1251
, the operation proceeds to step S
1253
. The processes in the steps S
1249
to S
1252
are performed until mouse dragging is suspended. When mouse dragging has been suspended, the operation proceeds to step S
1254
(step S
1253
). If the speed pattern
214
is not being dragged with the mouse in step S
1248
, the operation proceeds to step S
1254
.
The operation returns to step S
1240
until the setting completion button
160
is selected. When the setting completion button
160
has been selected (step S
1254
), information in the speed-instruction-method storage area
238
of the speed graph output information is outputted as data
2106
of speed instruction method of the locating program code. If the set locating control type
81
is locus control, information of the region-instructed-speed and final region instructed-speed storage area
239
is outputted as data
2600
pm
(1≦m≦M) of instructed speed of the passing point of the locus control locating program code and data
2600
of instructed speed of the location end point. If the set locating control type is another type, it is outputted as instructed speed data
2200
of the control-type corresponding data
2108
. Moreover, information in the speed-control-unit storage area
231
is outputted as speed-control-unit data
1801
of the acceleration/deceleration control parameter corresponding to the acceleration/deceleration control parameter number
1230
and the operation is ended (step S
1255
).
The above-mentioned location programming apparatus is able to generate a locating program by simply graphically setting an instructed speed pattern for the operation.
Moreover, the instructed speed pattern can visually be understood for any user. The instructed speed can easily be set and changed. Moreover, change in the speed pattern occurring when change has been performed can simultaneously be recognized.
Moreover, the relationship between the speed and parameters relating to the control can easily be understood.
12. Setting and Change in Limited Speed By Using Speed Graph
The operation for setting and changing the limited speed by using the speed graph will now be described with reference to
FIGS. 72
to
74
.
FIG. 72
shows an example of a locating programming window by using a speed graph when the limited speed is set and changed. Reference numeral
240
represents a speed movement pointer for vertically moving the speed line. When the mouse cursor is moved onto a limited speed line
206
, the speed movement pointer
240
is formed into an arrow cursor facing up and down as illustrated. When a dragging operation is performed, the pointer is able to vertically move in the speed-graph making and displaying area
204
. A point at which mouse dragging has been suspended is the set speed. Reference numeral
242
represents inclination of the acceleration pattern,
243
represents inclination of the deceleration pattern,
244
represents inclination of the rapid stop deceleration pattern and
214
represents the speed pattern.
The operation for setting and changing the limited speed will now be described with reference to a flow chart shown in FIG.
73
. The limited speed line
206
is located at the position of the set speed in the speed-graph making and displaying area
204
in the displayed initial window described with the speed graph. When the limited speed is changed (step S
1300
), the present limited speed line
206
is dragged with the mouse so that the speed movement pointer
240
is displayed so as to be vertically moved to an arbitrary position on the speed graph (step S
1301
). When the limited speed has been determined (step S
1302
), mouse dragging is suspended (step S
1303
). Then, the operation proceeds to step S
1304
. If the limited speed is not changed in step S
1300
, the operation proceeds to step S
1304
. If the limited speed is changed, the operation returns to step S
1300
. When the change of the limited speed has been completed (step S
1304
), the setting completion button
160
is selected (step S
1305
). Then, the operation is ended.
The operation for changing the limited speed will now be described with reference to a flow chart shown in FIG.
74
. If the limited speed line
206
is being dragged with the mouse (step S
1310
), the limited speed line
206
is moved to follow the speed movement pointer
240
. Moreover, also the inclination
242
of the acceleration pattern, the inclination
243
of the deceleration pattern, the inclination
244
of the rapid stop deceleration pattern and the speed pattern
214
are changed (step S
1311
). Moreover, information of the speed corresponding to the position of the limited speed line
206
on the speed graph is calculated so as to be stored in the limit-speed storage area
232
(step S
1312
). Thus, display on the limited speed display area
216
of the speed-information-value display area
203
is updated (step S
1313
). The processes in steps S
1311
to S
1313
are performed until mouse dragging is suspended. When mouse dragging has been suspended, the operation proceeds to step S
1315
(step S
1314
). When the limited speed line
206
is not being dragged with the mouse in step S
1310
, the operation proceeds to step S
1315
.
The operation returns to step S
1310
until the setting completion button
160
is selected. When the setting completion button
160
has been selected (step S
1315
), information in the limit-speed storage area
232
for the speed graph output information is outputted as limited-speed data
1802
of the acceleration/deceleration control parameter corresponding to the acceleration/deceleration control parameter number
1230
and the operation is ended (step S
1316
).
The above-mentioned location programming apparatus is able to easily set and change limited speed simultaneously with the locating programming operation.
Moreover, limited speed can always be recognized during locating programming. In addition, an error that “operation is performed at the limited speed because the instructed speed exceeds the limited speed” which is detected by the controller when the program is started can be prevented.
In addition, the relationship among the limited speed, the acceleration pattern and the deceleration pattern can easily be understood.
13. Setting of Acceleration/Deceleration Pattern Type By Using Speed Graph
The operation for setting the acceleration/deceleration pattern type by using the speed graph will now be described with reference to
FIGS. 72 and 75
to
77
.
FIG. 72
shows an example of a locating programming window by using a speed graph when the acceleration/deceleration pattern type is set and changed. Reference numeral
217
represents a acceleration/deceleration pattern selection button composed of a trapezoid acceleration/deceleration selection button
217
a
, an exponential acceleration/deceleration button
217
b
and an S-figure acceleration/deceleration selection button
217
c.
FIG. 75
shows an S-figure ratio setting window
250
which is displayed when the S-figure acceleration/deceleration pattern selection button is selected. Reference numeral
252
represents a 100% acceleration pattern in an acceleration region when the S-figure acceleration/deceleration control is performed in accordance with, for example, a sine curve. Reference numeral
251
represents a center line of the sine curve. Reference numeral
254
represents an S-figure-ratio setting pointer which is formed into an arrow cursor as illustrated when the mouse cursor has been moved onto the sine curve
252
. When a dragging operation causes the S-figure-ratio setting pointer
254
on the sine curve
252
, a symmetrical set region
253
for the S-figure acceleration pattern with respect to the center line
251
, that is, the S-figure ratio can be changed. A position at which dragging has been suspended indicate set data. Reference numeral
255
represents an S-figure-ratio setting completion button for completing setting of the S-figure ratio and closing the S-figure ratio setting window
250
.
The operation for setting and changing the acceleration/deceleration pattern type will now be described with reference to a flow chart shown in FIG.
76
. When the acceleration/deceleration pattern type is changed (step S
1400
), any one of the “trapezoid acceleration/deceleration selection button
217
a
”, “the exponential acceleration/deceleration button
217
b
” and the “S-figure acceleration/deceleration selection button
217
c
” of the acceleration/deceleration pattern selection button
217
is operated to perform selection (step S
1401
). When the S-figure acceleration/deceleration selection button
217
c
has been selected (step S
1402
), the S-figure acceleration/deceleration pattern region is set on the displayed S-figure ratio setting window
250
. Initially, the mouse is dragged on the sine curve
252
so as to display the S-figure-ratio setting pointer
254
. Then, the S-figure-ratio setting pointer
254
is moved to an arbitrary position on the sine curve so as to set the region for the S-figure acceleration pattern (step S
1403
). After the S-figure acceleration pattern region has been determined (step S
1404
), mouse dragging is suspended (step S
1405
). When the S-figure pattern region has been set (step S
1406
), the S-figure-ratio setting completion button
255
is selected (step S
1407
) to close the S-figure ratio setting window. Then, the operation proceeds to step S
1408
. If the S-figure pattern region is furthermore changed in step S
1406
, the operation returns to step S
1403
.
If the acceleration/deceleration pattern type is not changed in step S
1400
, the operation proceeds to step S
1408
. When a button except for the S-figure acceleration/deceleration selection button
217
c
has been selected in step S
1402
, the operation proceeds to step S
1408
. If the acceleration/deceleration pattern type is furthermore changed, the operation returns to step S
1400
. When setting of the acceleration/deceleration pattern type has been completed (step S
1408
), the setting completion button
160
is selected (step S
1409
). Then, the operation is ended.
The operation for setting and changing the acceleration/deceleration pattern type will now be described with reference to a flow chart shown in FIG.
77
. When the acceleration/deceleration pattern selection button
217
has been selected (step S
1410
), information of the selected acceleration/deceleration pattern type is stored in the acceleration/deceleration pattern type storage area
236
(step S
1411
). Moreover, a corresponding button is inversely displayed (step S
1412
).
If the selected acceleration/deceleration pattern type is the S-figure acceleration/deceleration (step S
1413
), the S-figure ratio setting window
250
is displayed (step S
1414
) so that the process for setting the S-figure acceleration/deceleration pattern region is performed. If the S-figure-ratio setting pointer
254
is being dragged with the mouse (step S
1415
), a S-figure setting region
253
indicated with the pointer is displayed on the 100% acceleration pattern
252
(step S
1416
). Then, information of the ratio corresponding to the S-figure setting region
253
is calculated so as to be stored in the acceleration/deceleration pattern type storage area
236
(step S
1417
). Then, a result of the calculation is displayed on the S-figure ratio display area
218
with figures (step S
1418
). The processes in steps S
1416
to S
1418
are performed until mouse dragging is suspended. When mouse dragging is suspended, the operation proceeds to step S
1420
(step S
1419
). If the S-figure-ratio setting pointer
254
is not being dragged with the mouse in step S
1415
, the operation proceeds to step S
1420
. The operation returns to step S
1415
until the S-figure-ratio setting completion button
255
is selected. When the S-figure-ratio setting completion button
255
has been selected (step S
1420
), the S-figure ratio setting window
250
is closed (step S
1421
). Then, the operation proceeds to step S
1422
.
If acceleration/deceleration pattern type selected in step S
1413
is not the S-figure acceleration/deceleration, the S-figure ratio display area
218
is blank-displayed (step S
1425
). Then, the operation proceeds to step S
1422
.
In accordance with information in the acceleration/deceleration pattern type storage area
236
, the acceleration pattern and the deceleration pattern of the speed pattern
214
are displayed on the speed graph (step S
1422
). Then, the operation proceeds to step S
1423
. If the acceleration/deceleration pattern selection button
217
has not been selected in step S
1410
, the operation proceeds to step S
1423
.
The operation returns to step S
1410
until the setting completion button
160
is selected. When the setting completion button
160
has been selected (step S
1423
), information in the acceleration/deceleration pattern type storage area
236
of speed graph output information is outputted as data
1806
of the acceleration/deceleration pattern type of the acceleration/deceleration parameter corresponding to the acceleration/deceleration control parameter number
1230
, and the operation is ended (step S
1424
).
The above-mentioned location programming apparatus enables the acceleration/deceleration pattern, that is, the control operation to easily be understood. Moreover, an acceleration/deceleration pattern suitable for a subject which must be controlled can easily be determined.
14. Setting and Changing Acceleration Time By Using Speed Graph

FIG. 78
shows an example of a locating programming window by using a speed graph for setting and changing acceleration time. Reference numeral
247
represents a time movement pointer for changing time data. When the mouse cursor is moved onto the time pointer, the time movement pointer
247
is formed into an arrow cursor facing right and left as illustrated. When a dragging operation is performed, the time movement pointer
247
is able to move in the speed-graph making and displaying area
204
to the right and left. A position at which mouse dragging has been suspended indicate set time. Reference numeral
248
represents an acceleration time range with which the width of acceleration time for which acceleration has been started to reach limited speed is indicated by the length of an arrow. Reference numeral
207
represents an acceleration time display area,
242
represents a inclination of the acceleration pattern and
210
represents a acceleration time pointer for changing acceleration time, that is, the inclination
242
of the acceleration pattern.
The operation for changing acceleration time will now be described with reference to a flow chart shown in FIG.
79
. The acceleration time pointer
210
is located at the position of set time in the speed-graph making and displaying area
204
in the displayed initial window described in the locating programming using the above-mentioned speed graph. When acceleration time is changed (step S
1500
), the acceleration time pointer
210
is dragged with the mouse so that the time movement pointer
247
is displayed which is moved to an arbitrary position in the right and left directions on the speed graph (step S
1501
). When the acceleration time has been set (step S
1503
), mouse dragging is suspended (step S
1504
), the operation proceeds to step S
1505
. If acceleration time is not changed in step S
1500
, the operation proceeds to step S
1505
. If acceleration time is furthermore changed, the operation returns to step S
1500
. If the operation for setting acceleration time has been completed (step S
1505
), the setting completion button
160
is selected (step S
1506
) and the operation is ended.
The operation for changing acceleration time will now be described with reference to a flow chart shown in FIG.
80
. When the acceleration time pointer
210
is being dragged with the mouse (step S
1510
), the acceleration time pointer
210
is moved to follow the time movement pointer
247
. Moreover, also the inclination
242
of the acceleration pattern, the acceleration time range
248
and the speed pattern
214
are changed (step S
1511
). Moreover, information of acceleration time corresponding to the length of the acceleration time range
248
on the speed graph is calculated so as to be stored in the acceleration-time storage area
233
(step S
1512
). Thus, display on the acceleration time display area
207
of the time-information-value display area
202
is updated (step S
1513
). The processes in steps S
1511
to S
1513
are performed until mouse dragging is suspended. When mouse dragging has been suspended, the operation proceeds to step S
1515
(step S
1514
). If the acceleration time pointer
210
is not being dragged with the mouse in step S
1510
, the operation proceeds to step S
1515
.
The operation returns to step S
1510
until the setting completion button
160
is selected. When the setting completion button
160
has been selected (step S
1515
), information in the acceleration-time storage area
233
of speed graph output information is outputted as acceleration time data
1803

The operation for calculating and displaying actual acceleration time in an acceleration period will now be described with reference to a flow chart shown in FIG.
84
. If the speed is not instructed, no operation is performed and the process is ended. If speed has been instructed (step S
1600
), actual acceleration time Tar with respect to instructed speed for the region
1
is calculated in accordance with Equation 1100 (step S
1601
). A result of the calculations is stored in the work area
283
for a result of calculations of acceleration/deceleration time and an actual-acceleration-time storage area
260
(step S
1602
).

In accordance with data in the actual-acceleration-time storage area
260
, the actual-acceleration-time display area
271

and actual-acceleration-time range
272
a
of the time-information-value display area
202
are displayed (step S
1603
).
The contents (A) of the area
120
for storing the number of set points are stored in the work area
280
for data of the number of regions (step S
1604
). Then, the work area
281
for the counter (a) of the number of regions is initialized to “1” (step S
1605
). If data A of the number of regions is larger than the counter a of the number of regions, the processes in step S
1607
to S
1612
are performed. Thus, actual acceleration time required for the acceleration region between passing points to reach the instructed speed is calculated. If data A of the number of regions is smaller than the counter a of the number of regions, the process for calculating and displaying the actual acceleration time is ended (step S
1606
).
If data A of the number of regions is larger than the counter a of the number of regions, the difference between the instructed speed in the region P
a
and that in the region P
a+1
is calculated in accordance with Equation 1101 so as to be stored in the work area
282
for changing speed (X) (step S
1607
). If the amount X of changed speed is larger than 0 (step S
1608
), an acceleration region is indicated. Therefore, actual acceleration time Tarx between regions P
a
and P
a+1
is calculated in accordance with the Equation 1102 so as to be stored in the work area
283
for a result of calculations of acceleration/deceleration time (step S
1609
). Then, the contents of the work area
283
for a result of calculations of acceleration/deceleration time are stored in the Pa→Pa+1 acceleration/deceleration-time storage area
263
(step S

of the time-information-value display area
202
are displayed (step S

). Then, the operation proceeds to step S
1612
.

Ta: acceleration time
Vmax: limited speed
If the amount X of the changed speed is zero or smaller than zero in step S
1608
, the same instructed speed or a deceleration region is indicated. Therefore, the operation proceeds to step S
1612
. Finally, the counter a for counting the number of regions is increased by one so that the counter is updated (step S
1612
). Then, the operation returns to step S
1606
. In step S
1606
data A of the number of regions and the counter a for counting the number of regions are again subjected to a comparison. If the counter a for counting the number of regions is larger than A, calculation and display of the actual acceleration time are completed.
The above-mentioned location programming apparatus enables actual acceleration time in an acceleration period of an instructed speed pattern to automatically be recognized when a locating programming process is performed. Moreover, acceleration time suitable for a subject which must be controlled can easily be determined.
16. Setting and Change of Deceleration Time By Using Speed Graph
The operation for setting and changing deceleration time by using a speed graph will now be described with reference to
FIGS. 78
,
85
and
86
.
FIG. 78
shows an example of a locating programming window by using a speed graph when the acceleration time is set and changed. A similar window is used when the deceleration time is set and changed as described below. Referring to the drawing, reference numeral
246
represents a deceleration time range in which the width of deceleration time required from limited speed to completion of deceleration and stop with the length of an arrow. Reference numeral
208
represents a deceleration time display area,
243
represents inclination of a deceleration pattern and
211
represents a deceleration time pointer for changing deceleration time, that is, the inclination
243
of the deceleration pattern.
The operation for changing deceleration time will now be described with reference to a flow chart shown in FIG.
85
. The deceleration time pointer
211
is located at the position of set time in the speed-graph making and displaying area
204
of the initially displayed window for use when the locating programming is performed by using a speed graph. When deceleration time is changed (step S
1700
), the deceleration time pointer
211
is dragged with the mouse so that the time movement pointer
247
is displayed which is moved to an arbitrary position in the right or left direction on the speed graph (step S
1701
). When deceleration time has been determined (step S
1703
), mouse dragging is suspended (step S
1704
). Then, the operation proceeds to step S
1705
. When deceleration time is not changed in step S
1700
, the operation proceeds to step S
1705
. When deceleration time is furthermore changed, the operation returns to step S
1700
. When deceleration time has been set (step S
1705
), the setting completion button
160
is selected (step S
1706
). Then, the operation is ended.
The operation for changing deceleration time will now be described with reference to a flow chart shown in FIG.
86
. When the deceleration time pointer
211
is being dragged with the mouse (step S
1710
), the deceleration time pointer
211
is moved to follow the time movement pointer
247
. Moreover, also the inclination
243
of the deceleration pattern, the deceleration time range
246
and the speed pattern
214
are changed (step S
1711
). Moreover, information of deceleration time corresponding to the length of the deceleration time range
246
on the speed graph is calculated so as to be stored in the deceleration-time storage area
234
(step S
1712
). Thus, display on the deceleration time display area
208
of the time-information-value display area
202
is updated (step S
1713
). The processes in steps S
1711
to S
1713
are performed until mouse dragging is suspended. When mouse dragging is suspended, the operation proceeds to step S
1715
(step S
1714
). When the deceleration time pointer
211
is not being dragged with the mouse in step S
1710
, the operation proceeds to step S
1715
.
The operation returns to step S
1710
until the setting completion button
160
is selected. When the setting completion button
160
has been selected (step S
1715
), information in the deceleration-time storage area
234
of speed graph output information is outputted as data
1804
of deceleration time of the acceleration/deceleration control parameter corresponding to the acceleration/deceleration control parameter number
1
and the operation is ended (step S
1716
).
The above-mentioned location programming apparatus is able to perform adjustment while change in the deceleration pattern occurring when the deceleration time is changed is confirmed.
17. Calculation and Display of Actual Deceleration Time in Deceleration Region By Using Speed Graph
The operation for calculating and displaying actual deceleration time in a deceleration region by using a speed graph will now be described with reference to

The operation for calculating and displaying actual deceleration time in a deceleration region will now be described with reference to a flow chart shown in FIG.
87
. If the speed is not instructed, no operation is performed and the process is ended. If speed has been instructed (step S
1800
), actual deceleration time Tdr with respect to instructed speed for the final region is calculated in accordance with Equation 1200 (step S
1801
). A result of calculations is stored in the work area
283

of the time-information-value display area
202
are displayed (step S

).
The contents (A) of the area
120
for storing the number of set points are stored in the work area
280
for data of the number of regions (step S
1804
). Then, the work area
281
for the counter (a) of the number of regions is initialized to “1” (step S
1805
). If data A of the number of regions is larger than the counter a of the number of regions, the processes in step S
1807
to S
1812
are performed. Thus, actual deceleration time required for the deceleration region between the passing points from instructed speed to completion of the deceleration and stop is calculated. If data A of the number of regions is smaller than the counter a of the number of regions, the process for calculating and displaying the actual deceleration time is ended (step S
1806
).
If data A of the number of regions is larger than the counter a of the number of regions, the difference between the instructed speed in the region P
a
and that in the region P
a+1
is calculated in accordance with Equation 1201 so as to be stored in the work area
282
for changing speed (X) (step S
1807
). If the amount X of changed speed is larger than 0 (step S
1808
), a deceleration region is indicated. Therefore, actual deceleration time Tdrx between regions P
a
and P
a+1
is calculated in accordance with the Equation 1202 so as to be stored in the work area
283
for a result of calculations of acceleration/deceleration time (step S

If the amount X of the changed speed is zero or larger than zero in step S
1808
, the same instructed speed or a acceleration region is indicated. Therefore, the operation proceeds to step S
1812
. Finally, the counter a for counting the number of regions is increased by one so that the counter is updated (step S
1812
). Then, the operation returns to step S
1806
. In step S
1806
data A of the number of regions and the counter a for counting the number of regions are again subjected to a comparison. If the counter a for counting the number of regions is larger than A, calculation and display of the actual deceleration time are completed.
The above-mentioned location programming apparatus enables actual deceleration time with respect to a deceleration region of an instructed speed pattern to automatically be recognized when locating programming is performed. Moreover, deceleration time suitable for a subject which must be controlled can easily be determined.

245
represents a rapid stop deceleration time range in which the width of rapid stop deceleration time required for the limited speed to completion of rapid stop and deceleration is indicated with the length of an arrow. Reference numeral
209
represents a rapid stop deceleration time display area,
244
represents inclination of rapid stop deceleration pattern and
212
represents a rapid stop deceleration time pointer for changing the rapid stop deceleration time, that is, the inclination

. The rapid stop deceleration time pointer
212
is located at the position of set time in the speed-graph making and displaying area
204
in the displayed initial window described in the locating programming using the speed graph. When the rapid stop deceleration time is changed (step S

), the rapid stop deceleration time pointer
212
is dragged with the mouse so that the time movement pointer
247
is displayed which is moved to an arbitrary position in the right or left direction on the speed graph (step S
1901
). When the rapid stop deceleration time has been determined (step S
1903
), mouse dragging is suspended (step S
1904
). Then, the operation proceeds to step S
1905
. If the rapid stop deceleration time is not changed in step S
1900

160
is selected (step S
1906
). Then, the operation is ended.
The operation for changing rapid stop deceleration time will now be described with reference to a flow chart shown in FIG.
89
. When the rapid stop deceleration time pointer
212
is being dragged with the mouse (step S
1910
), the rapid stop deceleration time pointer
212
is moved to follow the time movement pointer
247
. Moreover, also the inclination
244
of the rapid stop deceleration pattern
244
and the rapid stop and deceleration time range
245
are changed (step S
1911
). Moreover, information of rapid stop deceleration time corresponding to the length of the rapid stop and deceleration time range
245
on the speed graph is calculated so as to be stored in the rapid-stop-deceleration-time storage area
235
(step S
1912
). Thus, display on the rapid stop deceleration time display area
209
of the time-information-value display area
202
is updated (step S
1913
). The processes in steps S
1911
to S
1913
are performed until mouse dragging is suspended. When mouse dragging is suspended, the operation proceeds to step S
1915
(step S
1914
). If the rapid stop deceleration time pointer
212
is not being dragged with the mouse in step S
1910
, the operation proceeds to step S
1915
.
The operation returns to step S
1910
until the setting completion button
160
is selected. When the setting completion button

of speed graph output information is outputted a rapid stop deceleration time data

2000
), actual rapid stop deceleration time Tedr with respect to instructed speed for the region

). Thus, calculation and display of the actual rapid stop deceleration time are ended.
The actual rapid stop deceleration time with respect to the instructed speed for the region
1
is calculated as described above. Also calculation and display can be performed for the instructed speed for each region in accordance with Equation 1300.
The above-mentioned location programming apparatus enables actual rapid stop deceleration time with respect to each region of the instructed speed pattern to automatically be recognized when locating programming is performed. Moreover, rapid stop deceleration time suitable for a subject which must be controlled can easily be determined.

Then, display on the window is performed in accordance with information above. In accordance with information in the dwell-time storage area
295
, figures are displayed on the dwell time display area
290
of the time-information-value display area
202
. The dwell time range
291
is displayed and the dwell time pointer
292
is line-displayed at the end point of the dowel time range on the speed graph (step S
2103
). Then, the M-code setting/display area
293
and the limited-torque setting/display area
294
are sectioned into the number corresponding to the number of points set for the area
120
for storing the number of set points similarly to the speed change points (step S
2104
). In accordance with information in the M-code storage area
296
for each region, figures are displayed in the corresponding region of the M-code setting/display area
293
(step S
2105
). In accordance with information in the limited-torque storage area
297
for each region, figures are displayed on the corresponding region of the limited-torque setting/display area
294
(step S
2106
). Thus, the operation for initializing the auxiliary items is completed.
The operation for setting and changing the dowel time will now be described with reference to a flow chart shown in FIG.
94
. The dwell time pointer
292
is located at the position of set time in the speed-graph making and displaying area
204
as a result of the initializing operation. When dowel time is set (step S
2111
), the dwell time pointer
292
is dragged with the mouse so that the time movement pointer
247
is displayed which is moved to an arbitrary position in the right or left id on the speed graph time (step S
2112
). When dowel time has been set (step S
2114
), mouse dragging is suspended (step S
2115
). Then, the operation proceeds to step S
2116
. When the dowel time is not changed in step S
2111
, the operation proceeds to step S
2116
. When the dowel time is furthermore changed, the operation returns to step S
2111
. When dowel time has been set (step S
2116
), the setting completion button
160
is selected (step S
2117
). Thus, the operation is ended.
The operation for changing dowel time will now be described with reference to a flow chart shown in FIG.
95
. When the dwell time pointer
292

292
is moved to follow the time movement pointer
247
. Moreover, also the dwell time range
291
and the speed pattern
214
are changed (step S
2121
). Information of dowel time corresponding to the length of the dwell time range
291
on the speed graph is calculated so as to be stored in the dwell-time storage area
295
(step S
2122
). Thus, display on the dwell time display area
290
of the time-information-value display area
202
is updated (step S
2123
). The processes in steps S
2121
to S
2123
are performed until mouse dragging is suspended. When mouse dragging is suspended (step S
2124
), the operation proceeds to step S
2125
. When the dwell time pointer
292
is not being dragged with the mouse in step S
2120
, the operation proceeds to step S
2125
.
The operation returns to step S
2120
until the setting completion button
160
is selected. When the setting completion button
160
has been selected (step S
2125
), information in the dwell-time storage area
295
of speed graph output information is outputted as location end point dowel time
2606

81
is locus control. In a case where the locating control type storage area
81
is another locating control type, it is outputted as dowel time
2204
of data
2108
corresponding to the locating control type of the locating program code (step S
2126
). Thus, the operation is ended.
The location programming apparatus enables the ratio of time required from start to stop and dowel time to visually be recognized when locating programming is performed.

corresponding to the locating control type of the locating program code (step S

The above-mentioned location programming apparatus enables limited torque for the motor to graphically be set to correspond to the control operation.
23. Decomposition/Display of Instructed Speed to Each Axis Using Speed Graph in a Case Where Two or More Axes Are Interpolation-Controlled
The operation for decomposing and displaying instructed speed into a speed pattern for each axis when two or more axes are interpolation-controlled will now be described with reference to
FIGS. 100
to
103
.
FIG. 100
is a flow chart for calculating the speed of each axis when two axes are interpolation-controlled. In accordance with the locating control type storage area
81
shown in
FIG. 3
, determination is performed whether the interpolation is linear interpolation or circular interpolation (step S
3400
). If the interpolation is linear interpolation, the speed instruction method
238
in the locating program speed information structural diagram shown in
FIG. 67
is used to branch the process into instruction of synthesized speed, instruction of reference axis or instruction of major axis (step S
3401
). After branching has been performed, speed for each method is decomposed to each axis (step S
3402
).
A method of decomposing the speed to that for each axis in a case of where two axes are interpolation-controlled and synthesized speed is instructed will now be described with reference to a flow chart shown in FIG.
101
. Whether or not the position instruction method in the description of the position instruction method by using the coordinate graph is “absolute position instruction” or “relative position instruction” is read from the position-location-method storage area
121
shown in FIG.
13
. Then, branching is performed (step S
3403
). When relative position instruction has been set, movement amounts d
1
and d
2
to the instructed point are the amounts of relative movements set for the locating-end-point-position-information storage area
122
shown in FIG.
13
. Therefore, the relative movement amounts are read (step S
3404
). When absolute position instruction has been set, movement amounts d
1
and d
2
to the instructed point are calculated by the same method as that employed when the relative movement amounts are calculated when the position instruction method is changed from the “absolute position instruction” to the “relative position instruction” as described when the position instruction method using the coordinate graph has been described (step S
3405
). Moreover, synthesized movement speed v to the above-mentioned point is read from the region-instructed-speed storage area
239
shown in
FIG. 67
(step S
3406
). Then, the movement amount and synthesized speed of each axis are used to calculate the speed of each axis (step S
3407
). At this time, the speed of each axis is decomposed as follows:
v
1
=
v×{d
1
/{square root over ( )}(
d
1
2
+d
2
2
)} (Equation 1400)
v
2
=
v×{d
2
/{square root over ( )}(
d
1
2
+d
2
2
)} (Equation 1401)
When the speed instruction method is the instruction of a reference axis, decomposition to the speed for each axis is performed by the following method. The movement amounts d
1
and d
2
to the instructed point are calculated by the same method as that employed when the synthesized speed instruction is set. Assuming that the instructed speed is v, the speed of the reference axis is V
1
, the speed of another axis is v
2
, the movement amount of the reference axis is d
1
and that of another axis is d
2
, the speed of each axis is expressed by the following Equations 1402 and 1403:
v
1
=
v
(Equation 1402)
v
2
=
v
×(
d
2
/
d
1
) (Equation 1403)
When the speed instruction method is the major-axis reference instruction method, decomposition to the speed of each axis is performed by the following method. The movement amounts d
1
and d
2
to the instructed point are calculated by the same method as that employed in the case of the synthesized speed instruction method. Assuming that the instructed speed is v, the speed of an axis which is moved greater is v
1
and that of another axis is v
2
, the movement amount of the axis which is moved greater is d
1
and the movement amount of the other axis is d
2
, the speed of each axis is expressed by the following Equations 1404 and 1405:
v
1
=
v
(Equation 1404)
v
2
=
v
×(
d
2
/
d
1
) (Equation 1405)
In a case of locus control of a type that a plurality of speed switch points exist in one program, the foregoing calculations are performed by using the movement amount and the instructed speed for each point. Then, decomposition to each axis for each point is required.
Also in a case where the instructed speed for each point includes a pattern in which the acceleration and deceleration speeds are changed, the ratio of the speeds for the axes with respect to the instructed speed is expressed by Equations 1400 and 1401 when the synthesized speed instruction is employed, the same is expressed by Equations 1402 and 1403 when the reference axis speed instruction is employed and the same is expressed by Equations 1404 and 1405 when the major-axis reference instruction. Therefore, the instructed speed for each time period is required to be decomposed to the speed of each axis in accordance with the speed instruction method.
Although two axes are linear-interpolation-controlled, a similar method enables decomposition from instructed speed to the speed of each axis if three or more axes are linear-interpolation-controlled.
The speed pattern obtained as described above and decomposed to each axis is graphically displayed on the speed graph similarly to the instructed speed pattern.
FIG. 102
shows an example of display of the speed pattern decomposed to each axis on the speed graph. Reference numeral
300
represents a speed pattern of the second axis and
301
represents a selection button for selecting an axis to be displayed. The selection button
301
causes display to be performed by the number of the start axes in accordance with the number of start axes h
82
and the start axis number
83
in the structure of common information shown in FIG.
3
. Moreover, speed decomposed to each axis is calculated for the axis selected by the selection button so as to be displayed. Moreover, figures are displayed on the figure display area
302
for the decomposed speed.
Although the linear interpolation has been described, a method of the decomposition to the speed for each axis in the case of the circular interpolation will briefly be described with reference to FIG.
103
. Referring to
FIG. 103
, reference numeral
310
represents instructed speed in the case of the circular interpolation, the instructed speed being speed in the direction of a tangent of a circular arc. Reference numeral
311
represents a central point of the circular arc,
312
represents a present position,
313
represents a speed component in the direction of the X-axis and
314
represents a speed component in the direction of the Y-axis at the present position
312
. The speed components
313
and
314
for each axis can be obtained from the following Equation 1406 in accordance with the law of geometry:
v
1
=−
v ×
sin θ (
315
) (Equation 1406)
v: instructed speed (speed in the tangent direction of circular arc)
v
1
: speed component in the direction of X-axis
v
2
: speed component in the direction of Y-axis
(x
0
, y
0
): coordinates of central point of circular arc
(x, y): coordinate of a position at which speed is obtained
The method of obtaining the coordinate of the present position
312
by the Equation 1406 may be performed in such a manner that calculations for actually performing circular interpolation control are performed. Since the foregoing method does not relate to the decomposition of the speed, it is omitted from description.
The above-mentioned location programming apparatus enables change in the speed of each axis to graphically be displayed when interpolation operation is performed. Since the operation pattern for each axis can be recognized, determination of the capacity of the motor and the like can easily be performed.
24. Calculation/Display of Amount of Movement Performed Until Instructed Speed is Realized in Accordance With Acceleration Time by Using Speed Graph
The operation for calculating the movement amount required to accelerate the speed to reach instructed speed in accordance with acceleration time by using a speed graph and displaying a result will now be described with reference to
FIGS. 104
to
107
. Referring to a speed graph shown in
FIG. 104
, reference numeral
320
represents an axis of abscissa of the graph standing for the time axis,
321
represents an axis of ordinate standing for the speed,
322
represents speed v
1
before acceleration,
323
represents speed v
2
after acceleration and
324
represents an acceleration region. It is apparent that the movement amount required to accelerate speed v
1
to another speed level v
2
is the area of the acceleration region
324
indicated with diagonal lines. Therefore, if the area of the acceleration region
324
is obtained, the movement amount required to reach the instructed speed can be obtained regardless of the acceleration pattern. The area of the acceleration region
324
, that is, the movement distance required to perform acceleration can be calculated in accordance with the following Equation 1500 assuming that time corresponding to time axis of the speed graph is t, time at which acceleration is started is t
0
, time at which acceleration is completed is t
1
and a function indicating the acceleration pattern is f (t). Note that integrating period is t
0
to t
1
.
area (movement distance required to perform acceleration)=∫
f
(
t
)
dt
(Equation 1500)
An example of a method of calculating the distance required to accelerate the speed in accordance with Equation 1500 in a case of trapezoid acceleration/deceleration will now be described. In the case of the trapezoid acceleration/deceleration, Equation 1500 causes the area of a triangle formed when acceleration is performed in the speed graph. In accordance with actual acceleration time
260
shown in FIG.
81
and obtained by calculating and displaying the actual acceleration time in the acceleration region in the speed graph and in accordance with the instructed speed, the distance required to accelerate the speed can be obtained by the following Equation 1501:
dar
=(
tar=v
)/2 (Equation 1501)
dar: distance required to accelerate the speed
tar: actual acceleration time
v: instructed speed
A method of displaying an acceleration period from a start point to a position apart from the same for a movement distance required to accelerate the speed on the locating locus on the coordinate graph by using the movement amount obtained as described above and required to accelerate the speed will now be described with reference to
FIGS. 105
to
107
.
FIG. 105
is a flow chart showing the method of displaying an acceleration region on the coordinate graph. Initially, branching is performed depending on whether two or axes are interpolation-controlled or one axis is interpolation-controlled (step S
4500
). If one axis is controlled, the instructed speed is the speed of the above-mentioned axis (step S
4502
). If two or more axes are interpolation-controlled, the method of decomposing and displaying the instructed speed to the speed pattern for each axis is employed to decompose the instructed speed to the speed for each axis (step S
4501
). When interpolation control is performed, the actual acceleration time of the speed decomposed to each axis is the same as the actual acceleration time of the synthesized speed. Therefore, the actual-acceleration-time storage area
260
is read (step S
4503
). Then, the movement amount required to accelerate the speed is calculated for the number of start axes in accordance with Equation 1501 (step S
4504
). Assuming that the coordinate of the location start point of the two axes displayed on the coordinate graph are (x
0
, y
0
) and movement amounts of the two axes required to accelerate the speed are dx and dy, the coordinates at which the acceleration is completed are as follows (step S
4505
):
X-axis coordinates of point at which acceleration is completed=
x
0
+
dx
Y-axis coordinates of point at which acceleration is completed=
y
0
+
dy
(Equation 1502)
x
0
: coordinates of X-axis of point at which location is started
y
0
: coordinates of Y-axis of point at which location is started
dx: movement amount of X-axis required to accelerate speed
dy: movement amount of Y-axis required to accelerate speed
The thus-obtained coordinates at which the acceleration is completed and the location start point are displayed on the coordinate graph shown in
FIG. 106
as indicated with reference numeral
325
(step S
4506
). Note that the coordinates of the acceleration completion points may be displayed with figures as indicated with reference numerals
326
and
327
shown in FIG.
107
.
The above-mentioned location programming apparatus enables the position at which acceleration is completed to be displayed. Therefore, the position at which the speed is made to be constant can easily be detected.
25. Calculation/Display of Amount of Movement Performed From Start of Deceleration to Stop in Accordance With Deceleration Time and Using Speed Graph
The operation for calculating the movement amount required from start of deceleration to stop in accordance with the deceleration time and displaying a result will now be described with reference to FIG.
108
. Referring to a speed graph shown in
FIG. 108
, reference numeral
330
represents speed v
1
before deceleration,
331
represents speed v
2
after deceleration and
332
represents a deceleration region. It is apparent that the movement amount required to decelerate speed v
1
to another speed level of v
2
is the area of the deceleration region
332
indicated with diagonal lines. If the area of the deceleration region
332
is obtained, the movement amount required to decelerate the speed and stop the movement can be obtained regardless of the deceleration pattern. The area of the deceleration region
332
, that is, movement distance required to decelerate the speed can be calculated in accordance with the following Equation 1601 assuming that time corresponding to the time axis of the speed graph is t, time at which deceleration is started is t
0
, time at which movement is stopped is t
1
and a function indicating the deceleration pattern is f (t). Note that integrating region is t
0
to t
1
.
area (movement distance required to decelerate speed)=∫
f
(
t
)
dt
(Equation 1601)
When two or more axes are interpolation-controlled, the movement amount required to decelerate the speed is obtained from the speed graph of the synthesized speed shown in FIG.
82
. Thus, a movement amount which is required to decelerate the speed and which is a result of the interpolation can be obtained. In accordance with the speed graph showing the decomposed speed for each axis shown in
FIG. 102
, the movement amount for each axis required to decelerate and stop the movement can be obtained.
The thus-obtained movement amount required to decelerate the speed and stop the movement is used to display a deceleration region from the movement stop position to a position returned for a movement amount required to decelerate the speed on the locating locus of the coordinate graph. The display method is similar to the method of calculating and displaying the movement amount required to reach the instructed speed in accordance with the acceleration time by using the above-mentioned speed graph.
The above-mentioned location programming apparatus enables the deceleration distance in accordance with the deceleration time to easily be displayed. Therefore, the position at which deceleration is started can easily be understood.
26. Calculation/Display of Amount of Movement Performed From Deceleration to Stop in Accordance with Rapid Stop Deceleration Time and Using Speed Graph
The operation for calculating the movement amount required to decelerate the speed and stop the movement in accordance with the rapid stop deceleration time and displaying a result will now be described with reference to FIG.
109
. Referring to the speed graph shown in
FIG. 109
, reference numeral
340
represents speed v
1
before rapid stop deceleration,
341
represents speed v
2
after rapid stop deceleration and
342
represents a rapid stop deceleration region. It is apparent that the movement amount required for speed v
1
to rapidly be decelerated to another speed level of v
2
is the area of the rapid stop deceleration region
342
indicated with diagonal lines. If the area of the rapid stop deceleration region
342
can be obtained, a requited movement amount to rapidly stop the movement can be obtained regardless of the rapid stop deceleration pattern. The area of the rapid stop deceleration region
342
, that is the movement distance required to complete the rapid stop can be calculated in accordance with the following Equation 1701 assuming that time corresponding to the time axis of the speed graph is t, time at which rapid stop is started is t
0
, time at which the movement is stopped is t
1
and a function indicating the rapid deceleration pattern is f (t). Note that the integrating period is t
0
to t
1
.
area (movement distance required to rapidly stop movement)=∫
f
(
t
)
dt
(Equation 1701)
When two or more axes are interpolation-controlled, the movement amount required to rapid stop the movement is obtained from the speed graph of the synthesized speed shown in FIG.
82
. Thus, the movement amount which is required to accelerate the speed and which is a result of the interpolation can be obtained. In accordance with the speed graph decomposed to each axis shown in
FIG. 102
, the movement amount for each axis required to rapidly stop the movement can be obtained.
The thus-obtained movement amount required to rapid stop the movement is used to display a rapid stop deceleration region from the position at which rapid stop has been completed to a position returned for a movement amount required to rapid stop the movement on the locating locus of the coordinate graph. The display method is similar to the method of calculating and displaying the movement amount required to reach the instructed speed in accordance with the acceleration time by using the above-mentioned speed graph.
The above-mentioned location programming apparatus enables the rapid stop deceleration distance in accordance with the rapid stop deceleration time to be understood. Therefore, the distance required from instruction to rapid stop the movement can easily be understood.
27. Display of Maximum Speed and Rated Speed of Motor on Drive Shaft Using Speed Graph
The operation for displaying maximum speed and rated speed obtained from maximum number of revolutions and rated number of revolutions of a motor on a drive shaft will now be described with reference to
FIGS. 110
to
112
. The maximum number of revolutions and rated number of revolutions of a motor are limits with which the operation of the motor is guaranteed and which are determined for each type of the motors. In general, the number of revolutions is number of revolutions per minutes and indicated in units of [r/min]. On the other hand, the instructed speed for a locating program is expressed in a unit system of a machine which is operated by the motor.
FIG. 110
shows the structure of a parameter memory in which parameters for converting the number of revolutions of the motor into instructed speed unit. Reference numeral
350
a memory in which unit conversion parameter indicating the degree of movement in an instructed unit per rotation of the motor is stored.
FIG. 111
shows the structures of parameter memories on which the maximum number of revolutions for the motor and the rated number of revolutions are stored. Reference numeral
351
represents a memory on which the maximum number of revolutions for the motor is stored and
352
represents a memory on which the rated number of revolutions of the motor is stored.
In a case where the instructed unit is [mm] and the unit of the instructed speed is amount of movement [mm/min] per minute and the unit conversion parameter
350
indicates the distance which is in units of mm and for which the machine which is operated by the motor, the maximum speed converted into the instructed unit system from the unit conversion parameter
350
the maximum number of revolutions
351
can be obtained from the following Equation 1801:
maximum speed [mm/min]=unit conversion parameter [mm/r] maximum number of revolutions [r/min] (Equation 1801)
Also the rated speed can be obtained from the unit conversion parameter
350
and the rated number of revolutions
351
in accordance with the following Equation 1802:
rated speed [mm/min]=unit conversion parameter [mm/r]×rated number of revolutions [r/min] (Equation 1802)
Although the instructed unit is [mm] and the unit for the speed is [mm/min] in the description above, conversion may, of course, be performed if the unit system is another system.
The thus-obtained maximum speed and the rated speed are displayed on the speed graph.
FIG. 112
shows an example of the maximum speed and the rated speed on the speed graph. Reference numeral
353
represents a figure display area for the maximum speed,
354
represents a figure display area for the rated speed,
355
represents a maximum-speed display line showing the maximum speed and
356
represents a rated-speed display line showing the rated speed. The display is performed by a method similar to the method of displaying the limited speed described when the limited speed is set and changed by using the speed graph. Thus, the maximum speed and the rated speed obtained in accordance with the Equations 1801 and 1802 are used so that display on the speed graph shown in
FIG. 112
is performed.
The above-mentioned location programming apparatus is arranged in such a manner that the maximum number of revolutions and the rated number of revolutions of the employed motor are displayed on the speed graph. Therefore, the necessity of converting the maximum number of revolutions and the rated number of revolutions into the unit of the speed can be eliminated to determine limited speed.
28. Change of Acceleration/Deceleration Pattern Using Speed Graph
The operation for calculating and illustrating acceleration from data of a speed pattern by using the speed graph and changing the illustrated shape of the acceleration graph so as to change the acceleration/deceleration pattern on the speed graph will now be described with reference to
FIGS. 113 and 114
. The acceleration is an amount of change of the speed per unit time. Assuming that a function of the speed in terms of time t is v (t) and a function of the acceleration in terms of time is a (t), a fact has been known that the acceleration is expressed by differentiating the speed with time as shown in the following Equation 1900:
a
(
t
)=
dv
(
t
)/
dt
(Equation 1900)
The foregoing Equation 1900 can be used to obtain a graph showing change as time elapses from the speed graph and the graph can be displayed.
FIG. 113
is a graph showing the relationship between the speed and the acceleration when the trapezoid acceleration/deceleration, that is, when the acceleration/deceleration is performed at a constant acceleration. Reference numeral
360
represents a graph showing change in the speed as time elapses and
361
represents a graph showing change in the acceleration as time elapses corresponding to change in the speed as time elapses. In the graph
360
showing the change in the acceleration as time elapses, it is apparent that the area of the portion
362
indicated with diagonal lines is the same as the speed which has been made to be constant from the above-mentioned Equation 1900.
A method of displaying the acceleration graph shown in
FIG. 114
will now be described in such a manner that the trapezoid acceleration/deceleration is performed for example. When the trapezoid acceleration/deceleration is performed, that is, when the constant acceleration is employed, the acceleration a can be obtained as follows from actual acceleration time ta
260
determined as a result of calculations and display of the actual acceleration time in the acceleration region in the above-mentioned speed graph and instructed speed
239
stored in the locating program speed information area shown in FIG.
67
.
a=V/Tar
(Equation 1901)
a: acceleration
v: instructed speed
tar: actual acceleration time
Therefore, a straight line having a size of a which is the actual acceleration time tar is drawn from the point at which acceleration has been started. The acceleration is zero after the actual acceleration time has elapsed, that is, from the point at which acceleration has been completed to a next change in the speed. Then, the acceleration is required to be calculated and illustrated at each point at which the speed is changed. As a matter of course, the instructed speed v in the Equation 1901 is the different between the speed after the change and that before the change in a case where acceleration is not performed from a stopped state and in a case where the speed is changed at an intermediate locating point. As a matter of course, the straight line can be drawn in a case of deceleration similar to the acceleration.
The procedure for changing the acceleration and the acceleration time by using the acceleration graph will now be described.
FIG. 114
shows an example of the structure of a window for setting an acceleration graph obtained from a speed graph. Referring to
FIG. 114
, reference numeral
362
represents a graph showing acceleration,
363
represents a pointer for changing the acceleration and
364
represents a pointer for changing actual acceleration time. Reference numeral
365
represents an area for displaying the acceleration with figures. The pointer
363
is able to vertically move in the speed-graph making and displaying area
204
as a result of dragging operation of the mouse. A point at which the dragging operation has been suspended indicates the acceleration. When the acceleration is changed without change of the instructed speed, the actual acceleration time must be changed to correspond to the acceleration as can be understood from Equation 1901. In this case, the actual acceleration time can be obtained as follows as can be understood from Equation 1901:
tar=v/a
(Equation 1902)
Therefore, the actual acceleration time is again calculated in accordance with the Equation 1902 to correspond to the determined acceleration. In accordance with the result of the calculations, an acceleration graph is again drawn. Moreover, the obtained acceleration time is stored in the actual-acceleration-time storage area
260
of the actual acceleration/deceleration time information area shown in FIG.
81
. Moreover, the acceleration time
233
in the acceleration/deceleration control parameter area shown in
FIG. 66
is again calculated so as to be stored in the area
233
. It is apparent that the method of again calculating the acceleration time
233
can be performed in accordance with the following Equation 1903 from the description of the locating programming using the speed graph:
ta
=(
vmax/v
)×
tar
(Equation 1903)
ta: acceleration time
tar: actual acceleration time
vmax: limited speed
v: instructed speed
Also the acceleration graph permits the acceleration time to be changed. Referring to the drawing, the pointer
364
is able to move to the right and left in the speed-graph making and displaying area
204
when a dragging operation with the mouse has been performed. A point at which the dragging operation has been suspended indicates acceleration time. When the acceleration time is changed without change in the instructed speed, the acceleration must be changed as described above.
Although the process which is performed when acceleration is performed has been described, a similar method may, of course, be employed to change the deceleration time and acceleration for the deceleration process on the acceleration graph when the deceleration process is performed.
Although only the acceleration and the acceleration time are changed in the description above, the acceleration/deceleration pattern can be changed by deforming the acceleration graph.
The above-mentioned location programming apparatus enables acceleration time and deceleration time to be set by using the acceleration graph. Therefore, the acceleration time and deceleration time can be set while a user is conscious of the acceleration.
29. Display of Effective Speed Change Range Using Coordinate Graph
The operation for displaying an effective speed change range on the coordinate graph will now be described with reference to
FIGS. 115
to
117
.
FIG. 115
shows an example of a graph showing change in the instructed speed as time elapses when locating control is performed. Reference numeral
370
represents a graph showing change in the speed as time elapses. Reference numeral
371
represents a region in which deceleration is performed to a point at which location is completed. When the instructed speed is changed during the locating control, the position moved from the position at which deceleration has been started for a deceleration distance in accordance with a deceleration pattern is the position at which locating is completed. Therefore, speed cannot be changed even if change in the speed is requested during deceleration to the point at which locating is completed, that is, in a region
371
shown in FIG.
115
. That is, the region from the point at which locating has been started to a point at which deceleration is started toward the point at which locating is completed is the effective range for changing the speed.
A method of displaying the effective speed-change range on the coordinate graph will now be described in such a manner that two axes are linearly interpolated.
FIG. 116
shows an example of a coordinate graph showing an effective range in which speed can be changed. Reference numeral
380
represents a point at which locating is started,
381
represents a point a which deceleration is started and
382
represents a point at which locating is completed.
FIG. 117
is a flow chart for displaying the effective speed-change range on the coordinate graph. The description will be performed with reference to FIG.
117
. The deceleration distance required from the point at which deceleration has been started to the point at which locating is completed, that is, completion of the stop of the movement can be obtained by the method described when the movement amount is calculated and displayed (step S
700
). In accordance with the thus-obtained deceleration distance for each axis and the point at which locating is completed, the point at which deceleration is started toward the point at which locating is completed can be obtained as follows (step S
701
):
x
dp
=xe−dx
Y
dp
=ye−dy
(Equation 700)
xdp: coordinate of deceleration start point to locating completion point on X-axis
ydp: coordinate of deceleration start point to locating completion point on Y-axis
xe: coordinate of locating completion point on X-axis
ye: coordinate of locating completion point on Y-axis
dx: deceleration distance on X-axis
dy: deceleration distance on Y-axis
Therefore, the range from the locating start point
380
to the deceleration start point
381
obtained in accordance with Equation 700 is the effective speed-change range. Since the passage from the locating start point
380
to the deceleration start point
381
on the coordinate graph shown in
FIG. 116
is the effect speed-change range, the locating passage in the effective speed-change range is drawn on the coordinate with a changed type of line or the color of the like (step S
702
).
The above-mentioned location programming apparatus is able to prevent an error that “request for changing speed is executed during operation in which speed change is ineffective” detected by a controller during execution of the program when the locating programming is performed.
30. Locating Programming Using Coordinate Graph While Displaying List Form Locating Program

430
represents a list-form locating program display area on which a corresponding locating program list is displayed in accordance with information stored in the graphic programming work memory

81
of the common-information storage area

is updated in accordance with position information stored in the end-point-position information storage area
122
of the start axis number in addition to the process in steps S
321
to S
323
for the linear control by using the coordinate graph (step S
2300
). The processes in steps S
321

are performed until mouse dragging is suspended. When mouse dragging has been suspended, the operation proceeds to step S
325
. Then, a process similar to that when linear control is performed by using the coordinate graph is performed.
The above-mentioned location programming apparatus enables the process of setting a list-form locating program when the locus operation has been changed to simultaneously be recognized.

The operation for changing the movement direction and the speed/position switching point will now be described with reference to a flow chart shown in FIG.
141
. When the movement direction is changed (step S
3400
), the operation proceeds to step S
3401
. When the movement direction is the forward direction, the forward movement direction button
542
a
is selected (step S
3402
). When the movement direction is the reverse direction, the reverse movement direction button
542
b
is selected (step S
3403
). If the movement direction is not changed in step S
3400
, the operation proceeds to step S
3404
. When the amount of movement after the position control has been switched is changed in step S
3404
, the operation proceeds to step S
3405
. The speed/position switching point cursor
535
is dragged with the mouse so that the speed/position switching arrow pointer
536
is displayed which is moved to an arbitrary position on the speed graph. The operation returns to step S
3405
until the amount of movement after the position control has been switched in step S
3406
. After the amount has been determined, mouse dragging is suspended (step S
3407
). If the amount of movement after the position control has been switched is not changed in step S
3404
, the operation proceeds to step S
3408
. When the speed/position switching control is furthermore set, the operation returns to step S
3400
. When change has been completed (step S
3408
), the setting completion button
160
is selected (step S
3409
). Then, the operation is ended.
The operation for changing the speed/position switching point cursor
535
will now be described with reference to a flow chart shown in FIG.
142
. Initially, the area
570
and
571
for storing the amount of movement and the movement direction after the position control has been switched are initialized. In accordance with the initial values, the speed/position switching point cursor
535
is displayed, and the movement amount display
537
after the position control has been switched is displayed with diagonal lines. Display on the movement-amount display area
538
after the position control has been switched and the movement direction button
542
are inversely displayed (step S
3421
). In step S
3422
a deceleration distance is calculated in step S
3422
similarly to setting and change of the deceleration time by using the speed graph. In accordance with the following Equation 3400, a permissible deviation is calculated so as to be stored in the deceleration distance and permissible deviation storage areas
572
and
573
. Moreover, the areas
540
and
541
for displaying the deceleration distance and permissible deviation are displayed.
(permissible deviation)=(amount of movement after position control has been switched)−(deceleration distance) Equation 3400
When the forward movement direction button has been selected (step S
3423
), “forward direction” is stored in the movement direction storage area (step S
3425
). When the reverse movement direction button has been selected (step S
3424
), “reverse direction” is stored (step S
3426
). When the speed/position switching point cursor
535
is dragged with the mouse in step S
3427
, the speed/position switching arrow pointer
536
is displayed. Moreover, the speed/position switching point cursor
535
is moved to follow the mouse pointer (step S
3428
). In step S
3429
the amount of movement is calculated after the position control has been switched so as to be stored in the movement-amount storage area
570
after the position control has been switched. The movement amount display
537
after the position control has been switched is displayed with diagonal lines and the movement amount display area
538
after the position control has been switched are updated. In step S
3430
the deceleration distance and the permissible deviation are calculated so as to be stored in the areas
572
and
573
for storing the deceleration distance and the permissible deviation. Thus, the areas
540
and
541
for displaying the deceleration distance and the permissible deviation are updated. If the speed/position switching point cursor is not dragged with the mouse in step S
3427
, the operation proceeds to step S
3432
.
Finally, steps S
3428
to S
3430
are repeated until mouse dragging is suspended in step S
3431
. When mouse dragging has been suspended, the operation proceeds to step S
3432
. The operation returns to step S
3423
until the setting completion button
160
is selected in step S
3432
. When the setting completion button
160
has been selected, the operation proceeds to step S
3433
. Thus, information in the areas
239
,
570
and
571
for storing instructed speed in the region
1
, the amount of movement and the movement direction after the position control has been switched is outputted as data in the areas
2200
,
2800
and
2701
for storing the instructed speed of the speed/position switching control position program code, the movement amount and the movement direction after the position control has been switched. Moreover In step S

for storing acceleration/deceleration control parameter number, dowel time, M code for the region
1
, limited torque for the region
1
, M code for the region
2
and limited torque for the region
2
is output as data of the areas
2107
,
2204

2801
and
2802
for storing the acceleration/deceleration control parameter number of the speed/position switching control position locating position control, dowel time, M code, limited torque, M code after the position control has been switched and limited torque after the position control has been switched. Thus, INC is stored in the area for storing position instruction method, and then the operation is ended.
The above-mentioned structure is arranged in such a manner that the point at which overrunning takes place even if the deviation is zero is simply displayed on the speed graph. If movement of the speed/position switching point cursor to the region which causes overrunning to take place is inhibited, making of a speed/position switching control program which causes overrunning to take place with the locating controller
1001
can be prevented.
The above-mentioned structure is arranged in such a manner that the point at which overrunning takes place is always displayed on the speed graph. When an error message is outputted when a speed/position switching point cursor is located in the region in which overrunning takes place when the setting completion button
160
has been selected, making of a speed/position switching control program which causes overrunning to take place with the locating controller
1001
can be prevented.
The above-mentioned structure is arranged in such a manner that only the figures of the permissible deviation which is the maximum deviation with which overrunning can be prevented when the speed/position switching control is performed by the controller is simply displayed. If a deviation when the speed/position switching control has been performed by the locating controller
1001
is previously set and an error message is outputted when the permissible deviation is smaller than the predetermined value, making of a speed/position switching control program which causes overrunning to take place can be prevented.
The above-mentioned location programming apparatus enables the speed/position switching control locating program to easily be set and changed by using the speed graph. Moreover, a set range which prevents overrunning with the locating controller can easily be confirmed on the speed graph.

is set with position data corresponding to transition time, a time transition graph shown in
FIG. 157
is constructed.
FIG. 158
is a flow chart of the operation for making a position data table in which sequential locating corresponds to transition time. Operation cycle time for performing sequential operations is set (step S
4200
). Then, arbitrary transition time (
38

to
381
) is set (step S
4201
). Then, position data (
38
m
to
38

4202
). Information of the address operation of the position corresponding to transition time set in step S
4201

is temporarily restored in an internal memory (the graphic programming work memory
4
). If setting for arbitrary transition time required for the setting operation has been completed, the operation proceeds to a next step. If setting has not been completed, the operation returns to step S
4201
. The operations in steps S
4201

4203
are repeated until step S
4203
is completed.
Then, speed and acceleration characteristics of transition time set in the step S
4201
for each region is set (step S
4204
). If setting of the speed and acceleration characteristics for all regions has been completed, the operation proceeds to a next step (step S

are repeated until setting is completed. The speed and acceleration characteristic for each region set in step S
4204

50
of the address of the position corresponding to the transition time is dragged with the mouse so as to be moved to up, down, right or left so that a rough coordinate position is set (step S

4
(steps S
4273
and S
4274
). After processing of passing point data for one cycle has been completed, a button
55
for completing setting of a passing point is selected. Thus, generation is completed (step S
4276
). Thus, information shown in
FIG. 160
is stored in the graphic programming work memory
4
. If generation has not been completed, steps S
4270
to S
4275
are repeated until step S
4275
is completed.

4204
to S
4206
will now be described with reference to a flow chart shown in
FIG. 165. A
setting window is shown in
FIG. 167. A
transition time region (for example,
38
e
to
38
f
) which must be set is clicked with the mouse so as to be selected (step S
4280
). Then, the speed and acceleration characteristic (for example, constant acceleration
60
) in the selected region are selected and set (step S
4281
). Whether or not setting for the set region has been completed is determined (step S
4282
). If setting has been completed, a next speed and acceleration characteristic setting completion button
61
is selected and the process is completed (step S
4283
). Thus, information shown in
FIG. 161
is stored in the graphic programming work memory
4
. If setting has not been completed, steps S

to S
4282
are repeated until step S
4282
is completed.

4206
will now be described with reference to FIG.
159
. One cycle time set in step S
4200
is equally divided with an arbitrary resolution (when time for one cycle is divided into 1000, the resolution is 1000) (step S
4230
). Then, the amount of movement for each of arbitrary transition time periods set in step S
4201
and the speed and acceleration characteristics set in step S
4202
are used to calculate the amount of movement in each of the equally divided time periods (step S
4231
). In accordance with obtained amount of movement, position data is generated so as to be written on the position data table (step S
4232
). Whether or not generation of the position data table having position data for the resolution has been completed is determined (step S
4233
). If generation has been completed, the operation for generating the table is completed so that the position data table shown in
FIG. 162
is stored in the graphic programming work memory

. If generation has not been completed, steps S
4231
to S
4233
are repeated until step S
4233
is completed.
