Sensor Signal Disconnection Alarm

Was bedeutet 9073 ?

This alarm indicates an incorrect detection of a sensor signal disconnection, 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.

• Physical disconnection of sensor wiring to the control module.
• Damaged sensor cable or connector.
• Sensor has failed and is no longer transmitting a signal.
• Interference on the sensor signal line.
• Faulty input port on the control module.

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.
