26106
Overcurrent, KPP/KSP (axis)
Kuka · KR C4 Controller
What does 26106 mean?
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.
Common Causes
- Short-circuit between phases in the motor cable or within the motor windings.
- Sudden, high mechanical load or mechanical binding causing a motor stall.
- Malfunction within the KPP or KSP leading to incorrect current sensing or control.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Review the trace recording of the axis/current to identify the peak current value and timing.
- 2
Check the motor for shorted windings or mechanical seizure.
- 3
Inspect the motor cable for phase-to-phase or phase-to-ground short circuits.
- 4
Reinitialize the drive bus by performing a Power Off / Power On cycle.
- 5
Inspect KSP (KUKA SmartPAD) and KPP (KUKA Power Pack) components for damage.
