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
• Maximum 45 Hz
With p1349 = 0, resonance damping is active for the following output frequencies:
• 95 % of the motor rated frequency f
• Maximum 45 Hz
