Click steps to track your progress.

1. 1

   Perform a complete power cycle of the CNC system and spindle amplifier to reset the control software.

2. 2

   Check for any additional alarms or warnings on the CNC display or spindle amplifier diagnostic LEDs.

3. 3

   Verify the consistency of spindle-related parameters against a known good backup.

4. 4

   Inspect the optical fiber cable connecting the CNC to the spindle amplifier for any damage or secure connections.

5. 5

   If the error recurs, consider potential corruption of the spindle control software or a fault on the CNC mainboard/spindle interface.
