P 2.3.1.6 Inverter Thermal Overload Response
This parameter selects a response to the reaction of the drive for Inverter Thermal Overload protection. Inverter thermal overload is
detected when the drive operates for a long period at a specified output current level. Specific current levels and trip times depend on
the power unit type and rating. Following are the descriptions for the selections available for the parameter:

Selection Description
The drive issues a fault and stops modulation.
The drive derates the rectifier current (DC-link current) to mitigate the cause of rectifier thermal
overload. When the drive exits from the overload operation window, derating is stopped.
