Selection Criteria For The Output Reactor, Dv/D Filter Or Sinusoidal Filter - Siemens SIMOVERT FC Operating Instructions Manual

08.96
The specified lengths are valid for unshielded cables; for shielded cables, the values must be reduced to 2/3.
If several motors are connected to a drive converter, the sum of the cable lengths of all of the motor feeder
cables must be less than the permissible cable lengths.
When fully utilizing the permissible cable lengths, a line commutating reactor should be used and, if required, a
higher starting current set.
