POSITION CONTROL/FULL CLOSING CONTROL Mode Adjustment
Use the following procedure to perform the adjustment in position control for the OMNUC G5
Series.
Start adjustment.
Set the realtime autotuning to disabled (Pn002 = 0)
Set each parameter according to the parameter settings for different applications.
Operate based on the normal operation pattern and load.
Are the positioning time and other performances satisfied?
Increase Speed Loop Gain 1 (Pn101) to the extent
that hunching does not occur upon servo lock.
Decrease Speed Loop Integral Time Constant 1 (Pn102) to the extent
that hunching does not occur upon servo lock.
Does hunching (vibration) occur when the motor rotates?
Increase position loop gain to the extent
that overshooting does not occur.
Write to the EEPROM in the PARAMETER WRITE mode.
Adjustment completed.

10-4 Manual Tuning
Never adjust or set parameters to extreme values,
as it will make the operation unstable.
Failure to follow this guideline may result in injury.
Gradually change the value to adjust the
gain while checking the motor operation.
Yes
Adjustment completed.
Yes
Decrease Speed Loop Gain 1 (Pn101).
Increase Speed Loop Integral Time Constant 1 (Pn102).
If vibration persists after repeated adjustments
or the positioning is slow:
Increase Torque Command Filter Time Constant 1 (Pn104).
Set the damping frequency in the
Notch 1 Frequency Setting (Pn201),
Notch 2 Frequency Setting (Pn204),
Notch 3 Frequency Setting (Pn207) or
Notch 4 Frequency Setting (Pn210).
