Speed Control Mode Adjustment
Adjustments in speed control for the OMNUC G5 Series are very similar to Position Control
Mode adjustment.
Use the following procedure to perform the adjustment.
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 speed responsiveness and other performances satisfied?
Increase Speed Loop Gain (Pn101) to the extent
that hunting does not occur upon servo lock.
Decrease Speed Loop Integral Time Constant (Pn102) to the extent
that hunting does not occur upon servo lock.
Does hunting or vibration occur when the motor rotates?
Write to the EEPROM in the Parameter Write Mode.

because 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.

Decrease Speed Loop Gain (Pn101).
Increase Speed Loop Integral Time Constant (Pn102).
If vibration persists after repeated adjustments
or the positioning is slow:
Increase Torque Command Filter Time Constant (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).
