Output voltage boost derating
The drive can output a higher motor voltage than the supply voltage. This can
require derating of the drive output power depending on the difference between
the supply voltage and the output voltage to the motor for continuous operation.
400 V and 480 V drive types
This graph shows the required derating for 400 V and 480 V drive types.
