SPINDLE FAULT – NOT AT SPEED ERROR.
Definition:
During Spindle motion, the Spindle Drive Amplifier outputs a command to the Spindle Motor to rotate the Spindle. Feedback from the Spindle Encoder is received by the Spindle Drive Amplifier.
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) and repeat motion to see if error occurs again.
- If error occurs again, open the Electrical Cabinet door (please observe all safety precautions for opening the electrical cabinet door with Machine Power enabled). This must be done with the error message still displayed.

- Use the Electrical Schematics to verify the connection of the encoder feedback harness to the Spindle Drive Amplifier. Reseat connector and retry.
- If issue persists, check Encoder connector at Spindle Motor. Reseat connector and retry.
- If issue persists, open both ends of Encoder harness (at Spindle Motor and at Spindle Drive Amplifier) and verify wiring terminations at each pin. Resolder or replace harness.
- If problem persists, replace Spindle Drive Amplifier.
- If problem persists, replace Spindle Motor.
