6.3.7 Resonance Suppression

The resonance of mechanical system may occur due to excessive system stiffness or frequency response. However, this kind of resonance condition can be improved, suppressed, even can be eliminated by using low-pass filter (parameter P2-25) and notch filter (parameter P2-23, P2-24) without changing control parameter.

Applicable Control Mode: P/S/T		Section 6.3.7, P2-24
Unit: Hz

Range: 50 ~ 1000

Settings:

This parameter is used to set resonance frequency of mechanical system. It can be used to suppress the resonance of mechanical system. If P2-24 is set to 0, this parameter is disabled.
