This fault signifies a brief overcurrent event that exceeds the maximum current capacity of the KPP. Such events are typically caused by short-circuits or sudden, excessive load demands, indicating an electrical issue or severe mechanical binding.
Click steps to track your progress.
Review the trace recording of the axis/current to identify the peak current value and timing.
Check the motor for shorted windings or mechanical seizure.
Inspect the motor cable for phase-to-phase or phase-to-ground short circuits.
Reinitialize the drive bus by performing a Power Off / Power On cycle.
Inspect KSP (KUKA SmartPAD) and KPP (KUKA Power Pack) components for damage.
