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.
The damping control function works under the following conditions.
Precautions for Correct UsePrecautions for Correct Use
• Stop operation before changing the objects or switching with DFSEL.
• The damping control may not function properly or the effect may not be apparent under the
following conditions.

• If the ratio of the resonance frequency to anti-resonance frequency is large.
• If the damping frequency is outside the range of 1.0 to 200.0 Hz.
