5-23 Adaptive Filter

5-23 Adaptive Filter

Function
The adaptive filter reduces resonance point vibration by estimating the resonance frequency from
the vibration component that appears in the Servomotor 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 the Adaptive Filter Table Number Display
(Pn02F).
The resonance filter frequency can be obtained by specifying the Pn02F table No.

If the Adaptive Filter Table Number Display (Pn02F) has stopped changing (completed), a setting
of 2 will be retained, assuming that the resonance point does not change.
Write the data to the EEPROM if the results are to be saved.
