 Adjustment flow chart

(1)

Adjust the servo gain.

(2)

Check the vibration suppressing

anti resonance frequency.

Enter the vibration suppressing anti

resonance frequency

(parameters PA1_78, 80, 82 and 84).

(4)

Enter the S-curve

(parameters PA1_51, 52).

(5)

Check the effects.

Finely adjust the vibration suppressing anti

resonance frequency

(parameters PA1_78, 80, 82 and 84).

Adjust the inertia ratio of vibration

(7)

suppressing workpiece

(parameters PA1_79, 81, 83 and 85).

(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.
