The following are the selections for the parameter.
Selection Number Selection Name
1 Fault
2 Automatically derate
This parameter selects a response to the reaction of the drive for rectifier thermal overload protection. Rectifier thermal overload is
detected when the drive operates for a long period at a specified rectifier 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.
