Adaptive Tuning Procedure - Mitsubishi Electric MR-J5 User Manual

Adaptive tuning procedure

Yes
Is the performance satisfactory?
Increase the response level.
Tuning in the standard mode
Execute or re-execute adaptive tuning in
the standard mode. (Set "0" (standard) to
[Pr. PB01.3 Tuning accuracy selection]
and set "1" (automatic setting) to [Pr.
PB01.0 Filter tuning mode selection].)
Tuning will end after a certain period of
time. ([Pr. PB01.0 Filter tuning mode
selection] becomes "2" or "0".)
Has work-side/load-side vibration
Decrease the response level until
vibration or unusual noise is resolved.
*1 If vibration or noise occurs even with the required response satisfied, lower the response.

Operation
*1
No
No
Has vibration or unusual
noise occurred?
Yes
Tuning in the high accuracy mode
Execute or re-execute adaptive tuning in
the high accuracy mode. (Set "1" (high
accuracy) to [Pr. PB01.3 Tuning accuracy
selection] and set "1" (automatic setting)
to [Pr. PB01.0 Filter tuning mode
selection].)
Yes
been resolved?
No
Set the filter manually using the machine
analyzer.
End
If the vibration frequency cannot be
estimated when tuning is executed
during strong vibration or oscillation,
decrease the response setting temporarily
down to the vibration level and execute
tuning again.
Cause of vibration
The response level has been reached to
the machine limit.
The machine is too complicated to provide
the optimum filter.
