Probable Faulty Locations
Programming error
Program Example:
M03, M04, or M19 is designated with the spindle safety interlock ON.
Operation Example:
The spindle JOG pushbutton is pressed with the spindle safety interlock ON in a mode other than MANUAL.
Measures to Take
1)Close the door.
2)If the code 11, 12, or 13 appears, release the alarm by changing the parameter setting (the standard parameter for
switching between chuck work and center work).
