This fault signifies a brief but significant overcurrent exceeding the maximum current rating of the KPP, often indicative of a short-circuit condition. Such a fault can cause immediate damage to power electronics, motor windings, or associated cabling due to excessive current flow.
Click steps to track your progress.
Check trace recording of axis current to identify the overcurrent event.
Check motor for shorted windings or internal damage.
