ABB Error 39442 — Bleeder Resistance Too Low

What it means · Ce que ça veut dire

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

The bleeder resistance is too low 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 Resistance 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 bleeders may have the wrong resistance value or one of the bleeders may have failed, causing a short circuit.
• 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.
• The configuration data is described in Technical reference manual - System parameters.
