ABB robot collision / motion supervision error — error codes to check
Motion supervision trips when actual torque exceeds the expected model: wrong tool/payload data, mechanical binding, or a real collision. These codes tell the cases 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 →
