This alarm occurs when either the proximity sensor or marker is not detected during the Orient sequence, or the Spindle does not rotate to the specified angle after the proximity switch or marker is detected. Typically, Control Power is not disabled when this alarm occurs.

SPINDLE FAULT – ORIENT ERROR.
Definition:
During Tool Changes, Bore Orient cycles, Rigid Tap cycles, and Spindle Orient commands, the Spindle orients to a position to align the Spindle Drive Key to a specific angle. Typically, a proximity switch or encoder marker is used to determine the absolute position of the spindle nose, and then an offset set in the Servo Drive Amplifier is used to command the Spindle to rotate to the angle.
Corrective Actions:
- At the Control Console, select Manual mode followed by the RESET SERVOS softkey. Error message should clear after a few seconds. If necessary, re-enable Control Power (press Power and Start pushbuttons). Select ORIENT SPINDLE softkey in Manual mode and press Start to initiate Spindle Orient.
- If problem persists, check the alignment of the Orient proximity sensor. Check continuity to the Spindle Drive Amplifier. Replace proximity sensor if no continuity.
- If encoder marker is used, check connections of the Encoder harness at both the Spindle Motor and the Spindle Drive Amplifier.
- Use the Electrical Schematics to verify continuity at both ends of Spindle Encoder Harness. Replace harness if wiring terminations inside either connector are defective or are missing continuity.
