FANUC 16i / 18i / 21i
Description
When “Alarm 0” appears on the Fanuc CNC Control and the message “PLEASE TURN OFF POWER” appears on the screen, it is actually a safety warning from the machine.
This alarm occurs when a technician or operator changes parameters, the system cannot accept the changes in “Real-time”. The system must be powered off and restarted to reset the memory and load the updated data.
How to Fix Alarm
Turn off the main power switch of the machine and wait for about 10 to 15 seconds so that all the capacitors are discharged. Turn on the power again.
If you have not changed any parameters and this alarm is still occurring, it may be a sign of weak memory battery.
Reduce the number of digits before or after the decimal to fit the control’s limits.
