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.
