C5-50 Notch Filter Frequency
(0B14)
Expert
Machine resonance can cause high-frequency noise and vibration during operation. A notch filter can help prevent the
noise and vibration. Notch filters set the resonant frequency of the machine to remove specific vibrational frequency
components caused by machine resonance.
Note:
• Correctly set the value for the notch filter frequency. If the frequency value is too low for the speed loop response frequency, the speed
control function will not function correctly. Set the frequency to be a minimum of 4 times the speed loop response frequency.
• Set C5-50 = 0 [0 Hz] to disable the notch filter.

Expert
Note:
Set C5-50 = 0 [Notch Filter Frequency = 0 Hz] to disable the notch filter.
