Characteristics
Overload capability
The Power Modules are equipped with an overload reserve, e.g. to handle breakaway
torques.
In drives with overload requirements, the appropriate base load current must, therefore, be
used as a basis for the required load.
The overload data is valid under the precondition 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).
The base load current for low overload I
L
is based on a load duty cycle of 110% for 60 s or
150% for 10 s with a load duty duration of 300 s.
