end/device increased?
Has vibration
of workpiece end/device
been resolved?
Using a machine analyzer or
considering load-side vibration
waveform, set the vibration
suppression control manually.
Factor
Estimation cannot be made as load-side vibration
has not been transmitted to the servo motor side.
The response of the model loop gain has
increased to the load-side vibration frequency
(vibration suppression control limit).
Yes
Tuning ends automatically after
positioning operation is performed
the predetermined number of times.
