What it means
An application-level automatic stop input is open (cell logic wired into the system inputs). The robot is healthy — the CELL is holding it.
What to check
- Identify the mapped auto-stop signal and its upstream condition (PLC, door logic…).
- Correlate with the cell PLC diagnostics; the robot log only shows the consequence.
