MISMATCH RESULT OF MOTOR SPEED CHECK

Hva betyr SP9072 ?

The spindle detected a mismatch between the CNC result of the motor speed check and the spindle's own result. This indicates a discrepancy in speed monitoring data between the CNC and the spindle control, suggesting a potential fault in the SPM control printed-circuit board.

• The calculated motor speed does not match the monitored actual speed.
• Faulty tachometer or encoder providing incorrect speed feedback.
• Discrepancy in speed calculation algorithms between two monitoring points.
• High vibration or mechanical resonance affecting speed measurement.
