¿Qué significa SP0134 ?

An abnormal acceleration rate was detected in the spindle motor. This alarm indicates that the spindle experienced an unexpected or excessive acceleration, which could be due to a mechanical issue, an incorrect control parameter, or a faulty feedback system.

Causas comunes

  • DC link voltage is excessively high (above P1-01 threshold).
  • Over-voltage during regeneration or grid disturbance.
  • Faulty DC link capacitors.
  • Braking resistor not activating or is undersized.

Pasos de reparación & Lista de verificación

  1. 1

    Check for any mechanical binding, excessive load, or obstructions on the spindle motor that could induce abnormal acceleration.

  2. 2

    Verify the spindle motor's acceleration/deceleration parameters in the control system, ensuring they are set within the motor's operational limits.

  3. 3

    Monitor the spindle's actual speed and acceleration data via the control system to pinpoint the conditions under which the abnormal acceleration occurs.

  4. 4

    Ensure the motor's position and speed feedback system (sensor and cable) is providing accurate data, as incorrect feedback can trigger this alarm.

  5. 5

    If no mechanical or parameter issues are identified, consider a potential fault in the spindle amplifier's control logic or the motor itself, requiring further diagnosis or replacement.
