Overload capability

The Motor Modules have an overload reserve e.g. to handle breakaway torques.
In the case of drives with overload requirements, the appropriate base-load current must,
therefore, be used as a basis for the required load.
The criterion for overload is that the Motor Module is operated with its base load current
before and after the overload occurs (a load duration of 300 s is used as a basis here).
