Vibration Suppression Functions
 Notch Filters and Automatic Anti-resonance Setting
If the vibration frequency that occurs when you increase the servo gains is at 1,000 Hz or
higher, notch filters are effective to suppress vibration. If the vibration is between 100 Hz and
1,000 Hz, anti-resonance control is effective.
 Automatic Setting
To set vibration suppression automatically, use the parameters to enable notch filters and auto-
matic anti-resonance control setting.
The notch filter frequency (stage 1 or 2) or anti-resonance control frequency that is effective for
the vibration that was detected during tuning will be automatically set.
• Auto-setting Cancel Buttons
8-46
The automatically set notch filter frequencies or the anti-resonance control frequencies
may not always suppress vibration. Click the Cancel Button to reset the notch filter fre-
quencies or the anti-resonance control frequencies to the values from just before these
frequencies were set automatically.
When they are reset, vibration detection will start again.
