Machine Resonance Control
Torque Command Filter (Pn14, Pn1C)
Notch Filter
When machine rigidity is low, shaft torsion may cause resonance, leading to vibration or noise, thus
not allowing the gain to be set to a high value. In this case, the resonance can be suppressed by
using the two filter types.
The filter time constant is set to attenuate the resonance frequency. The cut-off frequency can be
calculated using the following equation.
Cut-off frequency (Hz) fc =
• Adaptive Filter (Pn23, Pn2F)
• Notch Filters 1 and 2 (Pn1D, Pn1E, Pn28, Pn29, and Pn2A)
Parameter
Parameter
The OMNUC G-Series Servo Drives use an adaptive filter to control vibration for loads that are
difficult to handle with the previous notch filters and torque filters, such as when each device has
a different resonance point. The adaptive filter is enabled by setting the Adaptive Filter Selection
(Pn23) to 1.
The OMNUC G-Series Servo Drives provide two normal notch filters. Notch Filter 1 can be used
to adjust the frequency and width, and Notch Filter 2 can be used to adjust frequency, width, and
depth with parameters.
