Functions To Suppress Vibration
For vibration frequencies above 1,000 Hz when servo gains are increased, the notch filter auto setting function
provides effective suppression. For vibration frequencies between 100 and 1,000 Hz, the anti-resonance con-
trol adjustment auto setting function is effective.
• Auto Setting
To use auto settings, enable automatically setting the notch filter and anti-resonance control in the parameter
settings.
Notch filter frequencies that are suitable for the vibration that was detected during tuning will be set for 1 step
and 2 step. If automatic setting is enabled for anti-resonance control, the anti-resonance control frequency will
be set automatically.
The window that is used to automatically set the notch filters is shown below.
Cancel
If the automatically set notch filter frequency (or anti-resonance control frequency) does not effectively
suppress vibration, click Cancel to reset to the preceding frequency.
When the frequency is reset, vibration detection will restart.
Vib Detect (vibration detection)
When automatically setting the notch filters and anti-resonance control is enabled, vibration detection is
performed manually. Click Vib Detect (vibration detection). The SERVOPACK will detect the current
vibration and set 1 step and 2 step to values that are suitable for the detected vibration. If you automati-
cally set anti-resonance control, the anti-resonance control frequency will be set. Even if the SERVO-
PACK does not detect vibration during one-parameter tuning, you can execute vibration detection
manually.
Anti-res Ctrl Adj (anti-resonance control)
Click Anti-res Ctrl Adj (anti-resonance control) to execute the anti-resonance control function if further
adjustment is required. See 9.5 Anti-Resonance Control Adjustment Function for details.
