What it means · Ce que ça veut dire
Open circuit in bleeder resistor circuit — ABB robot hardware event on the Open circuit in bleeder resistor resistor circuit (IRC5). Specific to this controller generation. Severity: Major. Field diagnosis below (French); your robot's own manual remains authoritative.
The bleeder resistor connected to the rectifier on drive link arg, drive module arg, is an open circuit. 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 Open circuit in bleeder resistor resistor circuit, 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 : This may be caused by a faulty bleeder resistor cable or bleeder resistor.
- - 1) Make sure the bleeder resistor cable is correctly connected to the rectifier unit.
- - 2) Make sure the cable and resistor is working correctly by measuring their resistance respectively.
- Disconnect before measuring.
- - 3) Replace any faulty component.
