Chapter ”Power modules”
This limit protects the power module from continuous overload.
The power module current is limited according to a characteristic if the
drive converter operates for an excessive time above the permissible
load limit. The load limit is set per parameter.
The limit is removed step–by–step if the power module is no longer
being operated above the load limit.
