Adjustment Functions
10-6 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 (Pn207 to Pn209) or Notch 4
(Pn210 to Pn212).
Refer to "10-7 Notch Filter" (P.10-28) for information on notch filter.
