 Adjustment flow chart
(1) Adjusting the servo gain
To ignore the vibration of the tip of the machine and reserve smooth stopping action of the
servomotor free from overshoot, refer to the description given in sections 5.1 through 5.5 to adjust
the servo gain.
If gain-related parameters are adjusted after the vibration suppressing anti resonance
frequency is set, the vibration suppressing anti resonance frequency must be adjusted
again. Perform gain adjustment first.
Check the vibration suppressing
anti resonance frequency.
Enter the vibration suppressing anti
resonance frequency
(parameters PA1_78, 80, 82 and 84).
Check the effects.
Finely adjust the vibration suppressing anti
resonance frequency
(parameters PA1_78, 80, 82 and 84).
Adjust the servo gain.(1)
Enter the S-curve
(parameters PA1_51, 52).
Adjust the inertia ratio of vibration
suppressing workpiece
(parameters PA1_79, 81, 83 and 85).
