6.4 Resonance damping
Drive functions
306 Function Manual, 11/2017, 6SL3097-4AB00-0BP5
The resonance damping function dampens active current oscillations that can occur under
no-load conditions. Resonance damping is active in a range between 5% and 90% of the
rated motor frequency (p0310), but only up to 45 Hz.

Note
Maximum frequency resonance damping
When p1349 = 0, the c
hangeover limit is automatically set to 95% of the rated motor
frequency, but only up to a maximum of 45
Hz.
