Related Parameters
The following parameters are automatically adjusted or used as reference when you adjust anti-
resonance control.
Do not change the settings while anti-resonance control is being adjusted.
Yes: The parameter is automatically set.
No: The parameter is not automatically set, but the setting is read during execution.
8.9.5
Suppressing Different Vibration Frequencies with Anti-
resonance Control
When you use anti-resonance control and increase the control gain, for some mechanisms,
vibration can occur at a higher frequency than the frequency for which vibration was sup-
pressed. If this occurs, you can suppress vibration for more than one frequency by adjusting
Pn166 (Anti-Resonance Damping Gain 2).
Required Parameter Settings
The following parameter settings are required to use anti-resonance control for more than one
vibration frequency.

Guidelines for Vibration That Can Be Suppressed
Anti-resonance frequency (Pn161): fa [Hz], Another vibration frequency that occurs when the
control gain is increased: fb [Hz]
•
Vibration frequencies: 100 Hz to 1,000 Hz
•
Range of different vibration frequencies: 1 < (fb/fa)
