751 SPINDLE ALARM DETECTION
(AL–XX)
This alarm indicates in the NC that an alarm is generated in the
spindle unit of the system with the serial spindle. The alarm is dis-
played in form AL–XX (XX is a number). Refer to (16) Alarms dis-
played on spindle servo unit .The alarm number XX is the number
indicated on the spindle amplifier. The CNC holds this number and
displays on the screen.
752 SPINDLE MODE CHANGE FAULT This alarm is generated if the system does not properly terminate a
mode change. The modes include the rigid tapping and spindle con-
trol modes. The alarm is activated if the spindle control unit does not
respond correctly to the mode change command issued by the NC.
