What it means · Ce que ça veut dire

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

The power seminconductor has been overloaded for joint arg, in drive unit number 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 Power Semiconductor Overload Error, 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 motor load may be too high, the motor may have stalled (maybe due to a collision), the motor load may be too high or there may not be enough cooling.
  • - 1) Check that the robot has not collided.
  • - 2) Check that the fans are running and that the air flow is not obstructed.
  • - 3) Check that the ambient temperature does not exceed the cabinet rating.
  • - 4) If the system contains external axes then check that motors are not too large for the drive units.
