ABB Error 39462 — DC Link Voltage at Critical

What it means · Ce que ça veut dire

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

The DC link voltage is critically high for the rectifier on drive communication link arg, drive module arg . No operation will be possible until after correcting the fault. The system goes to status SYS HALT. 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 at Critical, 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 user program may contain too much hard braking of the manipulators, which is more likely if the system contains additional axes.
• The brake resistors may also be faulty.
• Check the bleeder resistors to see that they are the correct resistance value for this drive module configuration.
• Check that none of the resistors have failed.
• Rewrite the user program to reduce the amount of hard braking.
