Serial data destroyed by noise

What does d3 mean?

Serial data transmitted between the sensor (serial) and the Spindle Amplifier was detected as corrupted by noise. This indicates a problem with the cable's shielding, external electrical interference, or the overall integrity of the data transmission path. Data corruption can lead to incorrect feedback or control.

• Noise interference affecting serial data transmission
• Inadequate shielding of the cable between the sensor (serial) and Spindle Amplifier

Click steps to track your progress.

1. 1

   Check the shielding effectiveness of the cable between the sensor (serial) and Spindle Amplifier.

2. 2

   Review the 'Detectors' section in the FANUC SERVO AMPLIFIER αi series Descriptions (B-65282EN) for specific cable requirements and grounding practices.
