Position
command
When the machine end vibrates, damping removes the vibration frequency from the commands,
reducing vibration.
• Stop operation before changing the parameters or switching with DFSEL/PNSEL.
• Under the following conditions, damping control may not operate properly or may have no effect.

Servo Drive
Set the frequency of the vibrating end.
• The Position Control Mode must be used.
• If forces other than commands, such as external forces, cause vibration.
• If the ratio of the resonance frequency to anti-resonance frequency is large.
• If the vibration frequency is outside the range of 10.0 to 200.0 Hz.
