ABB Error 39443 — Bleeder Resistor Overload Warning

What it means · Ce que ça veut dire

Bleeder Resistor Overload Warning — ABB robot hardware event on the bleeder resistor Resistor Overload Warning (IRC5). Specific to this controller generation. Severity: Major. Field diagnosis below (French); your robot's own manual remains authoritative.

The power consumed by the bleeder resistors is approaching overload 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 bleeder resistor Resistor Overload Warning, 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.
• - 1 Rewrite the user program to reduce the amount of hard braking.
