11-5 Damping Control

If the tip of the mechanical unit vibrates or the whole system sways, you can use the damping control
function to reduce vibration. This is effective on vibration generated by a machine of low rigidity. The
applicable frequencies are from 1 to 200 Hz.
You can set four frequencies, and use two of them at the same time.
