Sensor Signal Abnormality Alarm

What does 9083 mean?

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).

Click steps to track your progress.

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.
