Encoder Communications Disconnection Error

What does 084A0000 hex mean?

A communication disconnection was detected between the encoder and the Servo Drive. This indicates a loss of signal, potentially due to cable issues, power problems, or encoder failure, leading to loss of position feedback.

• Noise into the encoder cable.
• Contact failure of the signal line, and disconnection of the encoder.
• Power supply undervoltage to the encoder.
• Encoder failure.

Click steps to track your progress.

1. 1

   Inspect the encoder cable for physical damage, proper connection, and secure termination at both ends.

2. 2

   Measure the power supply voltage to the encoder to ensure it meets specifications.

3. 3

   Implement noise countermeasures on the encoder cable.

4. 4

   Check signal line continuity of the encoder cable.
