Chapter 6 Control Modes of Operation
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.
Relevant parameters:
P2 - 23
NCF1
Notch Filter 1 (Resonance Suppression)
Default: 1000
Applicable Control Mode: ALL
Unit: Hz
Range: 50 ~ 2000
Data Size: 16-bit
Display Format: DEC
Settings:
This parameter is used to set first resonance frequency of mechanical system. It
can be used to suppress the resonance of mechanical system and reduce the
vibration of mechanical system.
If P2-24 is set to 0, this parameter is disabled.
The parameters P2-23 and P2-24 are the first group of notch filter parameters and
the parameters P2-43 and P2-44 are the second group of notch filter parameters.
Notch Filter Attenuation Rate 1
P2 - 24
DPH1
(Resonance Suppression)
Default: 0
Applicable Control Mode: ALL
Unit: dB
Range: 0 ~ 32
Data Size: 16-bit
Display Format: DEC
Settings: 0: Disabled
This parameter is used to set magnitude of the resonance suppression that is set
by parameter P2-23. If P2-24 is set to 0, the parameters P2-23 and P2-24 are both
disabled.
The parameters P2-23 and P2-24 are the first group of notch filter parameters and
the parameters P2-43 and P2-44 are the second group of notch filter parameters.
