Hardware fault, KPP/KSP (axis)

What does 26117 mean?

The KPP/KSP axis device within the KUKA KR C4/KR C4 CK controller has detected an internal hardware fault. This is a critical error indicating a component failure within the module itself, requiring immediate attention.

• Internal component failure within the KPP/KSP module due to wear, electrical stress, or manufacturing defect.
• Physical damage or overheating resulting in internal circuit board failure.
• Power supply instability causing damage to internal electronics.

Click steps to track your progress.

1. 1

   Perform a power cycle (Power Off / Power On) of the KR C4/KR C4 CK controller to reinitialize the drive bus and the KPP/KSP module.

2. 2

   Check the device LEDs on the KPP/KSP module (refer to page 195 for LED descriptions) for specific fault indications (e.g., solid red LED indicating a fault).

3. 3

   Visually inspect the KPP/KSP module for any signs of physical damage, burning, bulging capacitors, or other indications of component failure.

4. 4

   If the fault persists after reinitialization and visual inspection, the KPP/KSP device is likely faulty and requires replacement.
