Vibration suppression control
tuning
Has vibration of workpiece
end/device increased?
Stop operation.
Execute or re-execute vibration
suppression control tuning. (Set [Pr.
PB02] to "_ _ _ 1".)
Resume operation.
Tuning ends automatically after positioning
operation is performed the predetermined
number of times. ([Pr. PB02] will be "_ _ _
2" or "_ _ _ 0".)
Is the target response reached?
Increase the response setting.
Has vibration of workpiece
end/device been resolved?
Decrease the response until vibration
of workpiece end/device is resolved.
Using a machine analyzer or considering
load-side vibration waveform, set the
vibration suppression control manually.
Factor
End
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).
