9.7.3 Recalculation
It is possible to alter one or more parameters, for example the maximum desired motor current, after an autotuning
procedure has been performed. To gain advantage of this change it is possible to do another auto tuning, but it is also
possible to perform a recalculation of the parameters based upon this change.
For the recalculation process it is necessary (after changing the desired parameters) to set the #14“Recalculation” to 1
and switch off the controller. Then wait a few seconds, switch on the controller and wait for line contactor to close and
for the OK message on the Calibrator’s first page.
The recalculation process is suggested after changing one or more of the following parameters:
Cal.

Maximum RMS motor current*

! VERY IMPORTANT
If a failure occurs during autotuning (Failure code greater than 15 see 13.1 Error Codes) autotuning stops.
If a failure is present before starting autotuning it is not possible to init the autotuning procedure.
