SPC SOFT DISCONNECT ALARM

What does 453 mean?

This alarm on Fanuc Series 0i-D/0i Mate-D with αi/βi Pulsecoders indicates a position-pole data error. This typically occurs due to an internal Pulsecoder failure or external contamination affecting its operation, particularly related to the absolute position feedback.

• Internal failure of the Pulsecoder, leading to incorrect position or pole data.
• Entry of cutting fluid or other contaminants into the Pulsecoder, causing internal damage or interference.
• Mechanical misalignment or damage to the Pulsecoder affecting its ability to detect pole data accurately.

Click steps to track your progress.

1. 1

   Inspect the Pulsecoder for any evidence of cutting fluid ingress, contamination, or physical damage.

2. 2

   Verify all connections of the Pulsecoder cable are secure and free from corrosion or oxidation.

3. 3

   Check for any physical obstruction or mechanical issue with the motor or Pulsecoder mounting that could cause position errors.

4. 4

   If signs of contamination or mechanical damage are found, or the issue persists after connection checks, replace the Pulsecoder unit.
