9.7.1 Derating factors
The derating factors shown below are applied to the rated DC output by the user.
They are not automatically implemented by the drive.

: Derating factor for higher switching frequency
If not all of the derating factors are considered, this could result in a drive overtempera-
ture condition.
The specic alarm indicates this condition and normal drive operation is stopped.
