Encoder Communications Error

What does 084B0000 mean?

The Servo Drive received illegal or corrupted data from the encoder multiple times, exceeding a specified error threshold. This suggests a problem with data integrity during communication, possibly due to electrical interference or power issues.

• Electrical noise interfering with the encoder cable data transmission
• Contact failure of encoder signal lines
• Physical disconnection affecting encoder data
• Power supply undervoltage to the encoder

Click steps to track your progress.

1. 1

   Measure the power supply voltage provided to the encoder at its input terminals.

2. 2

   Verify the integrity of all encoder signal lines by checking continuity and checking for proper termination.

3. 3

   Visually inspect all physical cable connections between the encoder and Servo Drive for disconnection or contact failure.

4. 4

   Verify proper grounding and shielding of the encoder cable to mitigate noise.
