The invention relates to electric drive apparatuses used in different industries for different applications more particularly to a method for configuration of an electric drive apparatus.
Electric drives are used in industry for different applications, such as for driving motors within the transportation industry, for driving different devices within the process and manufacturing industry as well as within the energy industry. There are applications commonly used for electric drives within the transportation industry for example in metro and railway traffic applications as well as in ship propulsion unit applications of the marine industry. Within the process and manufacturing industry, electric drives can be used for example in conveyer applications, in mixer applications or even in paper machine applications. Within the energy industry, electric drives can be used for example as electric drives for wind turbines of the wind power industry and as electric drives of the solar power industry.
Electric drives for electric motors may be divided into DC motor drives (DC, direct current) and AC drives (AC, alternating current). In a DC motor of a DC motor drive, a magnetic field is generated by the current through the field winding in the stator. This magnetic field is always maintained at right angles to the field generated by the armature winding. In this way, a DC motor's torque is generated, which torque can then be easily controlled in a DC motor drive by changing the armature current and keeping the magnetizing current constant. In a DC motor drive, also the DC motor speed can be controlled directly through armature current.
Within electric drives, the AC drives may further be divided into frequency-controlled AC drives, flux-vector-controlled AC drives and into AC drives utilising direct torque control (DTC, Direct Torque Control). In flux-vector-controlled AC drives and in direct torque control AC drives the torque of the three-phase motor can be controlled, whereas in frequency controlled AC drives the load dictates the torque level.
In the following, prior art will be described with reference to the accompanying
Electric drives are typically used in very demanding applications. Especially, in most of the applications used, the demand for a most optimal and reliable operation and for operational efficiency constantly increasing. The operation of an electric drive apparatus depends upon the most optimal configuration and upon the most optimal electric drive parameter set up. When electric drives are used in an application to drive the load, e.g. a motor, optimally, energy will be saved considerably. On the other hand, when electric drives are not used correctly or are not having the most optimal configuration in an application, energy savings will not be that great.
In a typical electric drive application, there are several subsystems in the electric drive apparatus and in the application setting that may all contribute to reliable operation and to the overall operational efficiency of the electric drive application. For example in
In a typical installation of an electric drive application setting electric drives are many times being replaced by a newer models as the existing electric drive apparatuses are broken or outdated. The newly installed electric drive apparatus also needs to be configured with a new set of parameter settings in accordance with the present electric drive application setting. This is problematic and time consuming. In some cases, it even may take some time while operating the electric drive in order to reach the most optimal configuration.
The evolvement of communication technology, particularly wireless communication technology and end user devices, has enabled versatile communication possibilities and introduction of different services. There are smartphone applications that allow a user of the smartphone to receive service recommendations for a machine, store operational data on the machine over the network connection, and troubleshoot the machine.

After the conversion 3-7 of said configuration parameter setting to a new configuration parameter setting is completed, the server 22 may inform 3-15 the user apparatus 20, e.g. by messaging, of said completed conversion. The user apparatus 20 detects the completion of the conversion and initiates a session 3-16 for downloading the new configuration parameter setting corresponding said newly installed new electric drive 24 from said server 22.

However, unlike in prior art solution, the user apparatus 20 outputs in the electric drive apparatus configuration tool application a possibility to start a download of a configuration parameter setting from an earlier installed old electric drive 21, and once a user input selecting to start said download is detected in point 3-3, the user apparatus 20 (i.e. the electric drive apparatus configuration tool application in said user apparatus 20) starts the download 3-3 of said configuration parameter setting.
Thus, the download session is between the old electric drive 21 and the user apparatus 20; the messages 3-4 illustrate the download session establishment and information exchange and download between them.
