What it means · Ce que ça veut dire
Close to singularity while External Motion Interface active — ABB robot hardware event on the Close to singularity while External Motion Interface active (IRC5). Specific to this controller generation. Severity: Major. Field diagnosis below (French); your robot's own manual remains authoritative.
The robot in External Motion Interface correction arg is too close to a singularity. The program execution is stopped, and the system goes to Motors Off state. Le texte constructeur de ce code n'existe qu'en anglais dans les manuels ABB dont il provient. Il est reproduit tel quel ci-dessus ; le manuel de votre robot fait foi.
What to check · Que vérifier
- Inspect the Close to singularity while External Motion Interface active, its wiring and connections first.
- Match this code against your robot's event-log timeline before swapping parts.
- Follow the French field checks below — they are the tested sequence for this fault.
- probable : The robot is close to a singularity, or too small numerical tolerance have been specified in the system parameters.
- Avoid moving too close to the singularity.
