Chapter 6 Control Mode of Operation

6.3.7 Resonance Suppression

When resonance occurs, it is probably because the stiffness of the control system is too strong or
the response bandwidth 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.
