11-9 Adaptive Notch Filter
The Adaptive Notch Filter reduces resonance frequency vibration by estimating the resonance fre-
quency from the vibration component that appears in the motor speed during actual operation and
automatically setting the frequency of the notch filter, which removes the resonance component from
the internal torque command.
You can check the values that are set automatically with 1st Notch Filter (3321 hex)/ 2nd Notch Filter
(3322 hex)/ 3rd Notch Filter (3323 hex)/ 4th Notch Filter (3324 hex) – Frequency Display (Subindex
82 hex), Q-value Display (Subindex 83 hex), and Depth Display (Subindex 84 hex).
Refer to 11-10 Notch Filters on page 11-23 for information on notch filter.
