ABB Error 34269 — AC Over voltage error

What it means · Ce que ça veut dire

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

In drive module arg , the input AC voltage is too high for the rectifier unit at drive unit position arg . No operation will be possible until the fault is corrected. 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 AC Over voltage error, 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 : - 1 High AC-voltage level to rectifier input.
• Check incoming mains voltage.
• If new installed system with mains transformer - check transformer voltage selection.
• If the problem remains then replace the unit.
