6. NORMAL GAIN ADJUSTMENT
(2) One-touch tuning execution
After the response mode is selected in (1), pushing the start button during driving will start one-touch
tuning. If the start button is pushed while the servo motor stops, "C 0 0 2" or "C 0 0 4" will be displayed
at status in error code. (Refer to (4) in this section for error codes.)
During processing of one-touch tuning, the status will be displayed in the progress window as follows.
One-touch tuning will be finished at 100%.
Completing the one-touch tuning starts writing tuning parameters to the servo amplifier. "0 0 0 0" is
displayed at status in error code. In addition, settling time and overshoot amount will be displayed in
"Adjustment result" after adjustment.
POINT
For equipment in which overshoot during one-touch tuning is in the permissible
level of the in-position range, changing the value of [Pr. PA25 One-touch tuning
- Overshoot permissible level] will shorten the settling time and improve the
response.
