Description

FIELD

The present invention relates to a positioning control apparatus that controls driving of a motor.

BACKGROUND

A motion SFC (Sequential Function Chart) programming language is used in order to perform motion control by a positioning control apparatus. The positioning control apparatus can be exemplified by a servo system controller. An example of such a motion SFC program is disclosed in Patent Literature 1. This motion SFC programming language is an SFC created exclusively for motion controllers and is written by combining symbols with which a program is written. In the symbols with which a program is written, signals or devices to control motions are recorded, and the motion control is performed by changing these signals or devices. There are motion SFC programming tools, which are engineering tools used to create such programs. The motion SFC programming tool is also called a software development support apparatus.

Further, when ascertaining or verifying the operations of such a program, an engineering tool called a digital oscilloscope tool is used by which, for control signals or devices used in the program, data is sampled at constant intervals and is graphically displayed in a time sequence on a screen. The digital oscilloscope tool is also called a sampling display apparatus.

DESCRIPTION OF EMBODIMENTS

A positioning control apparatus according to embodiments of the present invention will be described in detail below with reference to the drawings. Note that these embodiments are not intended to limit the present invention.

First Embodiment

FIG. 1 is a block diagram illustrating an example configuration of a positioning control apparatus according to a first embodiment of the present invention. A positioning control apparatus 10 illustrated in FIG. 1 is a positioning control apparatus that controls the driving of a motor 30 by a motion control program while displaying the operation screen of the motion control program. The positioning control apparatus 10 includes a software development support unit (software development supporter) 11 that includes the motion control program and creates and outputs a probe list; a sampling display unit (sampling display) 12 that outputs the probe list to a controller and displays data sampled in the controller; and a controller 13 that executes the motion control program and samples data in accordance with the input probe list. The software development support unit 11 can be exemplified by a motion control program development support apparatus. The sampling display unit 12 can be exemplified by a digital oscilloscope tool. Although FIG. 1 illustrates only a servo amplifier 20 and the motor 30, the present invention is not limited to this and multiple servo amplifiers and multiple motors connected to the servo amplifiers may be connected to the positioning control apparatus 10.

Note that the probe refers to information for identifying an object to be sampled, and examples of such information include a control signal name and an axis number or a device name. The probe list refers to an information group that is included in the sampling display unit and in which one or a plurality of probes are listed.

FIG. 2 is a block diagram illustrating an example of a hardware configuration that implements the positioning control apparatus 10. The positioning control apparatus 10 illustrated in FIG. 2 includes an input unit 101 that is an interface to which data is input by an operation performed by the user; a storage unit 102 that stores data output from the input unit 101; an output unit 103 that is an interface that outputs data stored in the storage unit 102; and a processing unit 104 that inputs and reads data to and from the storage unit 102 and that controls the input unit 101, the storage unit 102, and the output unit 103. The processing unit 104 includes a controlling unit 105 that controls the units; and a computing unit 106 that performs computing.

The input unit 101 can be exemplified by a mouse that is a pointing device and a keyboard. The storage unit 102 includes a main storage unit and an auxiliary storage unit. The output unit 103 can be exemplified by a display device.

In the present embodiment, a software development support program stored in the storage unit 102 implements the software development support unit 11 and a sampling display program stored in the storage unit 102 implements the sampling display unit 12.

FIG. 3 is a diagram illustrating an example of the operation screen of the software development support unit 11, the screen being displayed on the display device that is the output unit 103. In the operation screen illustrated in FIG. 3, symbols F0, G0, K0 are displayed in the middle. The symbols F0, G0, K0 denote a plurality of programs that belong to the selected project. Here the symbol F0 denoting a program is selected. The details of the selected symbol F0 denoting a program are displayed on the right side of the operation screen, and here “7 D3202L=163840L” is selected. Here, typically, by right-clicking with a mouse, i.e., the input unit 101, on the selected “7 D3202L=163840L”, the menu of “7 D3202L=163840L” is displayed. Here, as the menu of “7 D3202L=163840L”, only the operation of “Register in digital oscilloscope” is displayed. When the user selects “Register in digital oscilloscope”, the software development support unit 11 creates a probe list for the device “D3202” in order to output the probe list to the sampling display unit 12.

The probe list may be created by the software development support unit 11 adding a probe to the already-existing probe list that is stored in the memory of the sampling display unit 12. Alternatively, if no probe list exists, the probe list may be automatically created. Alternatively, as described in a later embodiment, the probe list may be created by reading data that has been processed by another terminal so as to be distributable.

FIG. 4 is a diagram illustrating an example of the operation screen of the sampling display unit 12, the screen being displayed on the display device that is the output unit 103. FIG. 4 is an operation screen for setting probes, and when “Deviation counter value” is selected from “Servo control data” on the operation screen for setting probes, it is indicated that the probe list for the user device “D3202” is automatically registered.

FIG. 5 is a sequence diagram illustrating the operation of the software development support unit 11 and the sampling display unit 12 in the present embodiment. In the sequence diagram illustrated in FIG. 5, the user selects a program on the operation screen of the software development support unit 11 (S10) and then selects a device of the program selected at S10 (S11). If the user performs an operation to select “Register” on the device selected at S11 (S12), the software development support unit 11 registers the probe of this selected device in order to automatically create a probe list (S13) and outputs the probe list to the sampling display unit 12 (S14). The sampling display unit 12 registers the probe list input from the software development support unit 11 (S15).

As described in the present embodiment, by selecting a control signal or a device on the operation screen of the software development support unit, a probe list can be automatically created. Thus, without referring to a plurality of screens, a control signal or a device to be sampled can be registered by performing a simple operation. Therefore, the production efficiency can be improved.

Second Embodiment

In the first embodiment, a description has been given of a mode in which only one symbol denoting a program is selected; however, the present invention is not limited to this. In the operation screen illustrated in FIG. 3, by performing a drag-and-drop operation, a plurality of symbols F0 and G0 that denote programs are selected, and probe lists can be created automatically and collectively for the symbols F0 and G0 denoting the programs of the selected project. Alternatively, in the operation screen illustrated in FIG. 3, by selecting all the symbols that denote the programs in the selected project, all the probe lists of the selected project can also be created automatically and collectively.

As described in the present embodiment, probe lists can be created automatically and collectively by selecting programs on the operating screen of the software development support unit without referring to a plurality of screens.

Third Embodiment

In the first and second embodiments, a description has been given of a mode in which one or a plurality of symbols denoting programs are selected; however, the present invention is not limited to this. In the present embodiment, with a parameter setting screen being displayed, a parameter necessary for motion control is selected on the parameter setting screen. Then, for the selected parameter, typically, by right-clicking with a mouse, i.e., the input unit 101, on the selected parameter, a menu is displayed. The user selects “Register in digital oscilloscope” from this menu, so that the software development support unit 11 creates a probe list made up of probes of control signals or devices for which the selected parameter is set and outputs the probe list to the sampling display unit 12. The sampling display unit 12 registers the automatically created probe list.

As described in the present embodiment, a probe list can be automatically created by using the parameter setting screen, which is an example of the operation screen of the software development support unit, without referring to a plurality of screens.

Fourth Embodiment

In the first to third embodiments, a description has been given of a mode in which, by selecting a symbol denoting a program, a control signal, or a device, the software development support unit 11 automatically creates a probe list from a probe and outputs the probe list to the sampling display unit 12, which registers the input probe list; however, the present invention is not limited to this. In the present embodiment, a project is selected on a project tree screen displayed in the left screen in FIG. 3 that is a part of the operation screen of the software development support unit, and a symbol denoting a program or a parameter is selected from the selected project. The software development support unit 11 creates a probe list from a probe of the selected symbol denoting a program or selected parameter and outputs the probe list to the sampling display unit 12. The sampling display unit 12 registers the automatically created probe list.

As described in the present embodiment, a probe list can be created automatically and collectively also by selecting one project at a time from the project tree screen, which is a part of the operation screen of the software development support unit, without referring to a plurality of screens.

Fifth Embodiment

In the first to fourth embodiments, a description has been given of a mode in which a symbol denoting a program, a control signal, a device, or a project is individually selected; however, the present invention is not limited to this. FIG. 6 is a diagram illustrating an example of the operation screen of the software development support unit 11, the screen being displayed on the display device that is the output unit 103. In the operation screen illustrated in FIG. 6, symbols F0, G0, K0 are displayed in the middle. The symbols F0, G0, K0 denote programs that belong to the selected project. Here the symbols F0 and G0 denoting programs are selected. Here, typically, a menu is displayed by right-clicking with a mouse, i.e., the input unit 101, on the selected symbols F0 and G0 denoting programs. Here, the menu only displays the operation of “Aim-specific list registration”. When the user selects “Aim-specific list registration”, the software development support unit 11 displays an “Aim-specific list registration” screen. FIG. 7 is a diagram illustrating an example of the operation screen of “Aim-specific list registration”. When the user enters a list name into the operation screen illustrated in FIG. 7 and presses the digital oscilloscope register button, a probe list is created from probes of programs, control signals, devices, or projects registered in the aim-specific list, and the created probe list is registered. Furthermore, the aim-specific list is registered in the storage unit 102. The user recalls the aim-specific list as needed and has the software development support unit 11 automatically create a probe list, and the sampling display unit 12 then automatically registers this probe list.

As such, when objects to form a probe list are grouped as an aim-specific list, the probe list can be re-registered by performing one simple operation collectively for all the objects.

If the aim-specific list described in the present embodiment is processed into library data and saved, the aim-specific list can be made distributable. FIG. 8 is a diagram illustrating an example where an aim-specific list has been processed into library data. If grouped objects are converted into library data to be distributable, this aim-specific list can be used in another terminal as well, which means that a probe list to be used in another terminal can be created collectively for all the objects by performing one simple operation.

The configurations shown in the above embodiments shows examples of the content of the present invention and can be combined with other publicly known techniques, and parts of each of the configurations can be omitted or changed without departing from the spirit of the invention.
