Omron SYSDRIVE 3G3HV SERIES - Suppression of Short-Cycle Vibration

3-39
D Suppression of Short-cycle Vibration
Vibration with a wavelength almost as long as the derivative time results from excessive derivative con -
trol.
The vibration can be suppressed by setting the derivative time to a smaller value. Set the propor -
tional
gain to a smaller value or the PID primary delay constant to a larger value if the vibration cannot be
suppressed after the derivative time is set to 0.00.
