No
Vibration suppression control tuning
Operation
Is the target response
reached?
Execute or re-execute vibration
suppression control tuning.
(Set [Pr. PB02] to "_ _ _ 1".)
Decrease the response until vibration
of workpiece end/device is resolved.
End
Yes
No
No
Yes
Increase the response setting.
Has vibration of workpiece
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.
([Pr. PB02] will be "_ _ _ 2" or
"_ _ _ 0".)
Stop operation.
Resume operation.
