What it means · Ce que ça veut dire

Signal exceeds max number of allowed bits — ABB robot hardware event on the Signal exceeds max number of allowed bits (IRC5). Specific to this controller generation. Severity: Major. Field diagnosis below (French); your robot's own manual remains authoritative.

Task: arg . The signal arg is too big. If using signals over 23 bits, use the data type triggiosdnum that accept signals up to 32 bits. Program ref: arg . 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 Signal exceeds max number of allowed bits, 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.
  • Group signals can have 23 bits or less if using datatype triggios in arg instruction.
