4.5 EMC
4.5.1 Internal EMC filter
It is recommended that the internal EMC filter be kept in place unless there is a specific reason for
removing it. If the drive is used as a motoring drive as part of a regen system, then the internal EMC
filter must be removed.
The internal EMC filter reduces radio-frequency emission into the line power supply.
For longer motor cables, the filter continues to provide a useful reduction in emission levels and
when used with any length of shielded motor cable up to the limit for the drive, it is unlikely that
nearby industrial equipment will be disturbed. It is recommended that the filter be used in all
applications unless the instructions given above require it to be removed, or where the ground
leakage current is unacceptable.
