6.3.7 Resonance Suppression
When resonance occurs, it is probably because the stiffness of the control system is too strong or
the response is too fast. Eliminating these two factors might improve the situation. In addition, low-
pass filter (parameter P2-25) and notch filter (parameter P2-23 and P2-24) are provided to
suppress the resonance if not changing the control parameters.

Default：
1000
Control
Mode：
ALL
Unit：
Hz
Range：
50 ~ 1000
Data Size：
16-bit
Format：
Decimal
Settings：
The first setting value of resonance frequency. If P2-24 is set to 0, this
function is disabled. P2-43 and P2-44 are the second Notch filter.

Default：
0
Control
Mode：
ALL
Unit：
dB
Range：
0 ~ 32 (0: disable the function of Notch filter)
Data Size：
16-bit
Format：
Decimal
Settings：
The first resonance suppression (notch filter) attenuation rate. When
this parameter is set to 0, the function of Notch filter is disabled.
NOTE
If the value of attenuation rate is set to 5, then, it would be -5dB.
