Related Parameters
The following parameters are automatically adjusted or used as reference when you execute
custom tuning.
Do not change the settings while custom tuning is being executed.
Yes: The parameter is automatically set.
No: The parameter is not automatically set, but the setting is read during execution.

The graph shows overshooting that occurred when the feed-
forward level was increased even more after step 3. In this
state, overshooting occurs, but the positioning settling time
is shorter. Tuning is completed if the specifications are met.
The tuning results are saved in the SERVOPACK. If over-
shooting occurs before the specifications are met, repeat
steps 3 and 4.
If vibration occurs before the overshooting is eliminated, the
vibration is suppressed with the notch filters and anti-reso-
nance control.
