4.4 NOMINAL SPEED ADJUSTMENT
It is necessary to set up the nominal motor speed that is used for detecting over-
speed alarm and motor running condition:
1. The Overspeed LED on the M6 control unit is ashing to indicate that the
control unit has no nominal motor speed programmed.
2. Start the motor and wait for it to stabilise until it reaches its nominal speed.
3. Hold down “RESET button” for 5 seconds.
4. The Overspeed LED on the M6 control unit turns off to indicate that the
process is complete.
5. Management of the overspeed alarm is enabled (parameter 17 value 1).
6. To reset the setting to nominal speed, it is necessary to hold down “RESET
button” for 5 seconds with the motor stopped. Performing this process, over-
speed alarm management is disabled (parameter 17 value 1).
The described process is valid, both for speed detection by frecuency of generator
as per motor pick-up.
