Sensor Signal Abnormality Alarm

Hva betyr 9083 ?

This alarm indicates an incorrect detection of an abnormal sensor signal, potentially due to wiring issues in the motor terminal box or non-shielded cable portions. This can also lead to large variations in low-speed motor operation.

• Sensor output signal is outside the expected operating range.
• Incorrect sensor calibration (e.g., encoder zero offset incorrect).
• External factor affecting sensor reading (e.g., temperature, vibration).
• Degradation of sensor performance over time.
• Parameter configuration mismatch for sensor type or range (e.g., P2-xx).

1. 1

   Inspect the wiring in the motor terminal box (transit box for built-in motors) to ensure proper connections and minimize non-shielded cable portions.

2. 2

   Check the feedback cable for physical damage or loose connections between the spindle motor and amplifier.

3. 3

   Verify all sensor signal connections (e.g., JFx connector for pulse coder, JYA2 for spindle sensor) for secure contact.
