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.

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.
