Resonance damping

Resonance damping damps oscillations in the active current, which often occur during no-

load operation. Resonance damping is active in the range between approximately 5% and

90% of the rated motor frequency (p0310), up to 45 Hz at most, however.

At p1349 = 0 the switching limit is automatically set to 95% of the rated motor frequency, up

to 45 Hz at most, however.
