14.10.4.6 Resonance damping
Overview
Resonance damping reduces speed oscillations for a motor without load or for sudden load
changes.
Description of function
With p1349>0, resonance damping is active for the following output frequencies:
• Between 6% and 90% of the motor rated frequency f
MotN
• Maximum 45Hz
With p1349=0, resonance damping is active for the following output frequencies:
• 95% of the motor rated frequency f
MotN
• Maximum 45Hz
