FANUC SRVO-082 (“WARN DAL alarm(Track encoder:…)”): The line tracking pulse coder is disconnected. First check: 1. Check the pulse coder cable. Likely part: Pulsecoder (Pulsecoder (motor encoder)).

Updated 2026-10-22 · LogrobotLM reference

Description

The line tracking pulse coder is disconnected.

Remedy

1. Check the pulse coder cable. 2. Replace the pulse coder.

Field diagnosis

The line tracking encoder is not seen by the interface board.

What to check

  • Check the cable at both ends (interface board and encoder) and the shield grounding; replace the cable, the encoder, then the interface board.
  • Note: A conveyor moved for maintenance and a forgotten connector: DAL at restart.
