Error

ABB 90206 (“Safety chain — General Stop fault”): General stop open: "The general mode safeguarded space stop circuit has been broken" (exact wording of the French message recorded on an IRC5 RobotWare 6.08 cabinet).

What it means

General stop open: "The general mode safeguarded space stop circuit has been broken" (exact wording of the French message recorded on an IRC5 RobotWare 6.08 cabinet). Motor power can no longer be established.

What to check

  • Identify the open device on the General Stop loop (barrier, gate, button).
  • Check the circuit wiring on the Panel Board / SIB and the state of the configuration jumpers.
  • Check the consistency of the two redundant channels.
  • Note: Correction: this code does NOT belong to the "... opened by SC" block (which starts at 90200). It is part of the hardwired safety chain group, alongside 90203 (enabling device), 90205 (automatic stop) and 90213 (dual-channel error). In the field log, it is the dominant safety event: 10 occurrences over 20 days, in bursts of 2 or 3 a few minutes apart.

Indicative field information — the robot manufacturer's manual and safety procedures always prevail. Never bypass a safety device; apply lockout/tagout (LOTO) before any physical intervention. How this reference is built →
