3) Vibration suppression control tuning procedure
The following flow chart is for the vibration suppression control 1. For the vibration suppression
control 2, set "_ _ 1 _" in [Pr. PX03] to execute the vibration suppression control tuning.
Vibration suppression control tuning
Yes
Increase the response setting.
Execute or re-execute vibration
suppression control tuning.
(Set [Pr. PB02] to "_ _ _ 1".)
Tuning ends automatically after
positioning operation is performed
the predetermined number of times.
([Pr. PB02] will be "_ _ _ 2" or
"_ _ _ 0".)
Decrease the response until vibration
of workpiece end/device is resolved.
Operation
Is the target response
reached?
No
Has vibration of workpiece
end/device increased?
Yes
Stop operation.
Resume operation.
Has vibration
of workpiece end/device
been resolved?
No
Using a machine analyzer or
considering load-side vibration
waveform, set the vibration
suppression control manually.
End
No
Yes
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).
