SERIAL DATA ERROR(INT)

What does 368 mean?

This alarm on Fanuc Series 0i-D/0i Mate-D with αi/βi Pulsecoders signifies a communication interruption with the built-in Pulsecoder. Common causes are cable disconnection, Pulsecoder failure, or external noise.

• Physical disconnection or damage to the Pulsecoder communication cable.
• Internal failure of the Pulsecoder preventing serial data transmission.
• Electrical noise interfering with the serial data communication.

Click steps to track your progress.

1. 1

   Inspect the Pulsecoder cable for physical damage, such as cuts, abrasions, or crushed sections.

2. 2

   Verify all connections of the Pulsecoder cable are secure at both the Pulsecoder and the servo amplifier.

3. 3

   Check for and mitigate sources of electrical noise (e.g., from power lines, solenoids) that could interrupt serial communication.

4. 4

   Perform a continuity test on each conductor of the Pulsecoder cable to rule out internal wire breaks.

5. 5

   If cable integrity and noise issues are ruled out, replace the Pulsecoder unit.
