Resonance damping
Description
Resonance damping damps oscillations in the active current, which often occur during no-
load operation.
Resonance damping is active in a range between 5% and 90% of the rated motor frequency
(p0310). The switch-off frequency is determined by p1349.
For p1300 = 5 and 6 (textiles) the resonance damping is internally disabled in order to be
able to precisely set the output frequency.
