What it means · Ce que ça veut dire

New unsafe robot path — ABB robot hardware event on the New unsafe robot path (IRC5). Specific to this controller generation. Severity: Major. Field diagnosis below (French); your robot's own manual remains authoritative.

The robot path has been cleared after a target has been modified in task arg . The robot will for that reason move towards the position pointed out by the move instruction at the program pointer. Move instructions between the modified target and the program pointer will be skipped. The programmed speed is used for this movement. The new untested path may contain obstacles that might cause a collision. 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.
