Adaptive Filter

Outline of the Function

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 applied to the Notch 3 (Pn207 to Pn209) and Notch 4
(Pn210 to Pn212)
Refer to 6-3 Notch Filters on page 6-8 for information on notch filter.
