This parameter enables the retry functionality (fault ride-through) after 1 of the common power conversion protections has activated.
The number of retries or the retrying window depends on the power unit type and rating. The protections that can utilize retry are:
Output current ground leakage fault
l
Output overcurrent faults
l
DC-link overvoltage and undervoltage faults
l
Brake resistor or switching element short circuit faults
l

0 Maximum derating
1 Minimum derating
This parameter selects a level for the derating of the switching frequency whenever it is needed. The drive features multiple protection
functions that can derate the switching frequency of the drive, to avoid operating conditions that are harmful for the drive. This
parameter can be used to influence the degree of derating. Following are the descriptions of the selections for this parameter:
