Damping Control
When an end of the equipment vibrates or the entire device shakes, damping control can be used to remove
the vibration frequency component from a position command for the reduction of vibration. Of the four
frequency settings, up to two can be used simultaneously.

Cautions
Damping control may not function normally or may not be effective in the following conditions.
Conditions hindering the functioning of damping control
Load condition
Vibration is excited by a factor other than a command (external force, etc.).
The ratio of the resonance frequency to the antiresonance frequency is large.
The vibration frequency is out of the 1.0 - 200.0 [Hz] range.
For the frequency of vibration,the responsion of the position
control is low.
