Communication error, KPP/KSP (axis)

What does 26114 mean?

An error occurred in the communication on the controller bus, specifically between the KPP/KSP axis drive and the KUKA KR C4/KR C4 CK controller. This communication interruption can prevent proper axis control, status updates, and overall robot operation.

• Damaged, loose, or improperly connected EtherCAT cabling.
• Incorrect configuration or integrity issues within the EtherCAT stack.
• Malfunction of the CCU (Central Control Unit) responsible for bus communication.
• Internal communication fault within the KPP (KUKA Power Pack) module.
• Internal communication fault within the KSP (KUKA Servo Pack) module.

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 communication links.

2. 2

   Inspect all EtherCAT cabling for damage, proper routing, and secure connections at both ends (e.g., CCU, KPP/KSP modules).

3. 3

   Verify the EtherCAT network configuration and status through the KUKA HMI or diagnostic tools for any reported errors or misconfigurations.

4. 4

   Check the status and LEDs of the CCU (Central Control Unit) for any fault indications.

5. 5

   Inspect the KPP module for any visible damage or warning indicators.

6. 6

   Inspect the KSP module for any visible damage or warning indicators.
