ABNORMAL PHASE DATA(INT)

What does 361 mean?

This alarm on Fanuc Series 0i-D/0i Mate-D with αi/βi Pulsecoders indicates a communication error or ID data error within the built-in Pulsecoder, suggesting a potential failure of the Pulsecoder itself or interference from external noise.

• Communication error in the Pulsecoder due to faulty internal components.
• ID data error within the Pulsecoder's signal processing.
• Pulse coder failure due to aging or internal defect.
• Electrical noise interfering with Pulsecoder communication.

Click steps to track your progress.

1. 1

   Check for sources of electromagnetic interference (EMI) or noise near the Pulsecoder cable and servo amplifier; mitigate if found.

2. 2

   Inspect the Pulsecoder cable and its connectors for any signs of damage, proper seating, and secure connections.

3. 3

   Verify that the Pulsecoder cable shield is properly grounded at the servo amplifier side.

4. 4

   If noise, cabling, and connections are confirmed to be in good condition, replace the Pulsecoder unit.
