ABB Error 50389 — Cartesian Soft Servo singularity

What it means · Ce que ça veut dire

Cartesian Soft Servo singularity — ABB robot hardware event on the boardsian Soft Servo singularity (IRC5). Specific to this controller generation. Severity: Major. Field diagnosis below (French); your robot's own manual remains authoritative.

The robot is too close to singularity which effects the Cartesian Soft Servo behavior. The robot behavior will be different from specified. 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 boardsian Soft Servo singularity, 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.
• Modify the program to avoid the singularity.
