Adjustment Procedure for Suppressing Different Vibration
Frequencies with Anti-resonance Control
Use the following procedure to make adjustments to suppress different vibration frequencies
with anti-resonance control.
Step
Use the gain adjustment and anti-resonance control.
1 Refer to the following section for details.
8.9.3 Operating Procedure on page 8-50
If there is vibration at a higher frequency than the vibration suppressed with anti-resonance
2
control in step 1, adjust Pn166 (Anti-Resonance Damping Gain 2).
Adjust Pn166 (Anti-Resonance Damping Gain 2) while checking to see if vibration reduction is
effective.
3 To adjust Pn166 (Anti-Resonance Damping Gain 2), increase the setting by 10% at a time start-
ing from the value that resulted in Pn163 (Anti-Resonance Damping Gain) from the adjustment
in step 1.
If the vibration disappears, the adjustment is completed.
4 However, if the vibration does not disappear even when you adjust Pn166 (Anti-Resonance
Damping Gain 2), reduce the tuning level or feedback level until vibration does not occur.
