Set notch depth for 1
st
resonant notch filter.
Under normal circumstances, please use factory default settings. If resonance is under control,
in combination with Pr2.01 and Pr2.02, Pr2.03 can be reduced to improve current loop
responsiveness which allows higher mechanical stiffness settings.

When Pr2.06 value is higher, notch depth becomes shallow, phase lag reduces. Under normal
circumstances, please use factory default settings. If resonance is under control, incombination
with Pr2.04 and Pr2.05, Pr2.06 can be reduced to improve current loop responsiveness which
allows higher mechanical stiffness settings.
