Adaptive Filter - Omron R88M-K Series User Manual

11-6 Adaptive Filter

The adaptive filter reduces resonance point vibration by estimating the resonance frequency
from the vibration component that appears in the motor speed during actual operation and
automatically sets the frequency of the notch filter, which removes the resonance component
from the torque command.
The automatically set notch filter frequency is set in Notch 3 (3207 to 3209 hex) or Notch 4
(3210 to 3212 hex). Refer to 11-7 Notch Filters on page 11-21 for information on notch filter.
