ABB Error 39608 — DC link voltage too low

What it means · Ce que ça veut dire

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

The DC link voltage is too low for the Power Unit at 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 DC link voltage too low, 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 incoming mains voltage to the rectifier unit is out of specification.
• Check for other hardware event log messages regarding mains voltage problem.
• Check incoming mains voltage.
• Change the mains tolerance min so that the mains voltage is inside the specified interval.
• Check that the correct voltage is selected with jumpers on the transformer (optional).
