What it means · Ce que ça veut dire

The precision will be lost — ABB robot hardware event on the The precision will be lost (IRC5). Specific to this controller generation. Severity: Major. Field diagnosis below (French); your robot's own manual remains authoritative.

Task: arg . Optional argument arg is used, and the group signal has arg bits. This can cause loss of precision in the variable used in optional argument arg . Program ref: arg . The program execution is stopped immediately. 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 The precision will be lost, 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 : Argument arg is used, and it is a risk that the precision of the value is lost.
  • Group signals consisting of 23 bits or less can be represented by the num data type, and group signals of 32 bits or less can be represented by the dnum data type, if they are used in a RAPID program.
  • To avoid loss of precision in the used variable in arg , use optional argument arg instead.
