Step Operation
1
Use the gain adjustment and anti-resonance control.
Refer to the following section for details.
8.9.4 Operating Procedure on page 8-50
2
If there is vibration at a higher frequency than the vibration suppressed with anti-resonance
control in step 1, adjust Pn166 (Anti-Resonance Damping Gain 2).
3
Adjust Pn166 (Anti-Resonance Damping Gain 2) while checking to see if vibration reduction is
effective.
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.
4
If the vibration disappears, the adjustment is completed.
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.
