If vibration thought to be caused by the Servo Driver occurs in the machinery, adjusting the torque
command filter time constant may cause the vibration to subside. The lower the value is set, the bet-
ter the response of the control that can be achieved. There are limits, however, depending on the
conditions of the machinery.

• A notch filter can be set for internal torque commands (commands to the current loop). A notch filter
• If mechanical resonance is occurring, a notch filter can be used to prevent it. This makes it possible
• With W-series AC Servo Drivers, two notch filters (notch filters 1 and 2) can be set.
Note This is a filter setting for the purpose of preventing machine resonance that cannot be elimi-

nated by simply adjusting the gain. If it not set carefully, it may have the unintended effect of
making machine operation unstable. Adjust the setting while monitoring machine operation by
means such as the torque command monitor. Also, provide an emergency stop switch that can
be pressed to immediately stop the machinery.
