8.2.3 Derating due to switching frequency
The following diagram shows the output current, depending on switching frequency. To limit the
thermal losses in the drive controller, the output current must be reduced.
Note: The switching frequency is not reduced automatically!
The max. output values can be determined from the following characteristic curve.
