Unknown status flag received, KPP/KSP (axis)

What does 26115 mean?

The EtherCAT master within the KUKA KR C4/KR C4 CK controller received an unknown or unexpected status flag from the KPP/KSP axis device. This indicates a potential software error, firmware inconsistency, or corrupted data during EtherCAT communication, leading to an uninterpretable device state.

• Software error or bug in the EtherCAT master's firmware or control application.
• Firmware inconsistency or incompatibility between the EtherCAT master and the KPP/KSP slave module.
• Temporary corruption of communication data due to electrical noise or cabling issues.
• Unexpected internal state or error within the KPP/KSP module that generates an unrecognized status flag.

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 reset the EtherCAT master and drive bus communication.

2. 2

   Verify that the KUKA KR C4/KR C4 CK controller software and KPP/KSP firmware versions are compatible and up-to-date according to KUKA documentation.

3. 3

   Check for any recent software updates or configuration changes that might have introduced the issue and revert if necessary for testing.

4. 4

   Inspect EtherCAT cabling for integrity, as physical layer issues can sometimes lead to corrupted data interpretation.

5. 5

   Monitor EtherCAT communication status via system diagnostics for recurring patterns or other associated errors.
