Please respect following motor cable length and PWM switching frequency dependency:
FN 5040 / FN 5045 FN 5040 HV
*In case a step-up transformer is used, then the length is meant to be between the filter and transformer.
Required drives settings
Ensure the motor drive switching frequency is set to the required minimum switching frequency (see filter
selection table). Higher frequencies are allowed. The mode of operation must be “scalar” (V/Hz). Check
the drives manual whether special settings are necessary. For any questions please contact the drives
manufacturer.
If the drives settings are not correct, the filter may be damaged!
