6.3.7 Resonance suppression unit
When resonance occurs, it is probably because the stiffness of the control system is too high or
the response bandwidth is too great. Eliminating these two factors can improve the situation.
In addition, use the low-pass filter (P2.025) and Notch filter (P2.023, P2.024, P2.043 - P2.046,
and P2.095 - P2.103) to suppress the resonance if you want the control parameters to remain
unchanged.
Refer to Chapter 8 for detailed descriptions of the relevant parameters.
