Siemens SINAMICS G220 Operating Instructions Manual page 627

If the overload response does not prevent a converter overload, then the converter switches
off the motor and issues a fault.
Overload response when p0290 = 13
We recommend this setting for driven loads with a high starting torque.
The converter signals an alarm for an impending overload condition.
If the converter is operated with an increased pulse frequency, when an alarm is active, then
the converter reduces its pulse frequency starting at the pulse frequency setpoint p1800.
The converter only reduces the pulse frequency for an excessively high chip temperature of
the power electronics or for an excessively high heat sink temperature.
When the overload has been eliminated, the converter increases the pulse frequency back to
the pulse frequency setpoint p1800.
If the overload response does not prevent a converter overload, then the converter switches
off the motor and issues a fault.
