Unknown device status, KPP/KSP (axis)

What does 26116 mean?

The KPP/KSP axis device within the KUKA KR C4/KR C4 CK controller is reporting an unknown or undefined status. This indicates an internal issue where the device is in an uninterpretable state, preventing the controller from correctly assessing its operational condition.

• Internal software or hardware fault within the KPP/KSP module.
• Corrupted device configuration or parameters stored in the KPP/KSP.
• Severe communication issue leading to a complete misinterpretation of the device's status.
• Transient electrical disturbance affecting the KPP/KSP module's internal state.

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 attempt to reset the KPP/KSP device's internal state.

2. 2

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

3. 3

   Verify that the KPP/KSP module configuration and parameters are correct and have not been corrupted.

4. 4

   Inspect EtherCAT cabling for damage or loose connections, as communication integrity is crucial for proper status reporting.

5. 5

   If the issue persists, consider temporarily swapping the KPP/KSP module with a known good spare to isolate if the fault lies with the module itself.
