Motor Tuning Errors
GEARED MOTOR
In old motors the auto-tuning may fail: in these cases the auto-tuning type 1 (at point 10 select P04 = 1) can
be executed but in this case the values P06 and P12 must be manually entered.

Acceptable values of P12 are between 0.5 and 5 Hz.
For instance, for a 4-pole motor, the Rated Frequency is 50 Hz, the synchronous speed is 1500 rpm and
the Rated Speed is on the motor nameplate (always in revolutions per minute).
GEARLESS MOTOR
In case of a problem "Error 52 = er7 Error VVVF" will show in the MENU ERRORS. In this case please
check the connections of the motor encoder, clear the errors in the "Errors" menu and repeat the poletuning
procedure from point 14.
After the poletuning procedure try to move the elevator in maintenance in up and down for some motor
revolutions. If it moves correctly the procedure is over, otherwise, in the event of an error of the VVVF (ere
or Ocx or Os), reverse the two motor phases changing the VVVF’s H190 parameter, clear the errors in the
"Fault" menu and repeat the poletuning procedure.
