ABB Error 50501 — Short movements

What it means · Ce que ça veut dire

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

One or more consecutive move instructions resulted in movements close to zero length. Task: arg . Program ref. arg . Programming with multiple close to zero length movements in a robot program can lead to high CPU load which can make zones to be converted into finepoints (event message 50024). Very close programmed points can also lead to non-smooth robot motion. 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 Short movements, 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 : Multiple move instructions with the same programmed position or subsequent move instructions with short distance between programmed positions.
• Increase the distance between the programmed positions.
• Remove redundant intermediate programmed positions.
• If the behavior of the robot and the system is ok, the sensitivity of this event message can be adjusted by using the system parameter 'Max allowed short segments' in topic Motion and type Motion Planner.
