Overload capability

The Motor Modules in the chassis format are equipped with an overload reserve to handle
breakaway torques, for example.
In the case of drives with overload requirements, the appropriate base load current must,
therefore, be used as a basis for the required load.
For overload, the following precondition applies: The drive is operated with its base load
current before and after the overload occurs (a duty cycle duration of 300 s is used as a
basis here).
