10.7.1 Overload capacity
Load cycle with base load current – typical for the selection of asynchronous and servomotors
The characteristic load cycle consists of a load and a load relief period. In the load re-
lief period, the output current must not exceed the specified value. After this load relief
period, overload is possible again.
