Control units for small electric drives with universal software interface

This contribution deals with a design of software interface for control units of different types of electric drives. Major part of control units software can be uniform, only the power circuit differs, as the analysis of existing solutions has shown. Thus it is possible to design universal software interface, in terms of this analysis, consisting of interconnected cooperating modules. This paper describes objectives and implementation of such modules, and also provides description of proposed universal interface architecture. The method of employment is shown on a case of control units for drives with DC and stepper motors.
