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 as a maximum 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 Motor Module is operated at its factory-set pulse frequency
at output frequencies > 10 Hz.
Additional information on the overload capability is provided in the Low Voltage
Configuration Manual and in the SINAMICS S120 Function Manual Drive Functions.
