Vibration suppression control tuning
Yes
Is the performance satisfactory?
Increase the response level.
Has work-side/load-side
Execute or re-execute vibration suppression
control tuning. (Set "1" (automatic setting) to
[Pr. PB02.0 Vibration suppression control 1 -
Tuning mode selection].)
Tuning ends automatically after positioning operation is
performed the predetermined number of times.
([Pr. PB02.0] becomes "2" (manual setting) or "0"
(disabled).)
Has work-side/load-side vibration
Decrease the response level until
work-side/load-side vibration is resolved.
When adjusting the vibration suppression control manually based on the result of the machine analyzer or the vibration
waveform of the load side, set the following parameters. Set the following servo parameters to meet the applicable and
recommended range. Refer to the following.

Set the vibration suppression control
manually from the vibration waveform of
the machine analyzer or load side.
End
Cause of vibration
The load-side vibration frequency cannot be estimated
because the load-side vibration has not been transmitted
to the servo motor side.
The model control gain value has been reached to the
response level of the load-side vibration frequency
(vibration suppression control limit).
