Overload capability

The Power Modules are equipped with 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 Power 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).
Another precondition is that the Power Module is operated at its factory-set pulse frequency
at output frequencies > 10 Hz.
