What it means · Ce que ça veut dire

Unit not stopped in a controlled position — ABB robot hardware event on the Unit not stopped in a controlled position (IRC5). Specific to this controller generation. Severity: Major. Field diagnosis below (French); your robot's own manual remains authoritative.

The robot arg is semi coordinated to unit arg from another task and the unit has been moved or the regain to the path failed. Program run or restart will be interrupted. 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 Unit not stopped in a controlled position, 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.
• Check all programs that the semi coordinated movement is separated with finepoints and WaitSyncTask instructions before and after the movement and that the unit is not moved between.
• Note that WaitSyncTask also is needed after the semi coordination before SyncMoveOn and SyncMoveResume.
• Check that the unit is moved to the wanted position before the semi coordinated movement.
• After SyncMoveOff, SyncMoveSuspend, ActUnit, DeactUnit or ClearPath the unit must be moved (with a new movement instruction) to a position to define the frame so the other task can read it.
• The position can be a new position, or the current position of the unit.
