Background. Modern electric drives have the structural form of electronic units with microprocessor control. In the process of serial production of electric drives, their technical control is required, namely, checking the serviceability of hardware, including logical and analog input and output circuits, power circuits, digital interfaces, built-in sensors and specialized microchips. To carry out such tests and automate them, it is necessary to develop software and hardware for the test and control equipment, as well as specialized software for the electric drive subject to checking. Thus, the development of such software for the electric drive is relevant.
Materials and methods. The authors have applied the methods of algorithmization of control processes, methods of system analysis, methods of model-based development of software and its debugging, as well as the methods of experimental research.
Results. An algorithm is proposed to check the hardware of an electric drive, representing a sequence of actions and calculations associated with the input, output and processing of logical and analog signals, the formation of currents and voltages in power circuits, as well as access control to built-in elements distributed between the electric drive as a subject to check, the test and control equipment and the personal computer used as a control device, the coordination of messages which is carried out via digital interfaces. A test mode is introduced into the electric drive software, isolated from the operation of the electric drive for its intended purpose in the main mode. Hardware handlers as well as a set of parameters and commands are provided.
Conclusions. Technical control of the electric drive allows us to promptly identify its faults immediately after manufacture. The proposed algorithm to test the hardware of the electric drive and automation of its implementation facilitates introduction of its technical control in the technological process of production.
