Maintenance Instruction Related To Fanuc Spindle Alarm
When a serial spindle alarm occurs, the following number is displayed on the CNC. n is a number
corresponding to the spindle on which an alarm occurs. (n = 1 : First spindle: n = 2 : Second spindle;
etc.)
Note
Note that the meanings of the SPM indications differ depending on which LED, the red or yellow LED, is
on. When the red LED is on, the SPM indicates a 2-digit alarm number. When the yellow LED is on, the
SOM indicates an error number that designates a sequence problem (for emergency stop state not
released).
