(10) Alarm list (serial spindle) 

When a serial spindle alarm occurs, the following number is displayed 
on the CNC. 
 

NOTE 

*1  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 SPM indicates an error number that 
designates a sequence problem (for example, 
when a rotation command is entered with the 
emergency stop state not released). 

 

See "Error Codes (Serial Spindle)." 

*2  For serial spindle alarms with a number not listed, 

refer to the following documents depending on the 
spindle motor to which a connection is actually 
made.
