The EtherCAT master has received an unknown status flag from the KPP or KSP module for a specific axis, indicating a software error within the EtherCAT master. This suggests an unexpected communication state.
Click steps to track your progress.
Verify KUKA system software version and KPP/KSP firmware compatibility for the affected axis.
Inspect EtherCAT communication cables and connectors for the affected axis for damage, proper routing, and secure connections.
Check diagnostic LEDs on the KPP/KSP axis module and the EtherCAT master in the KR C4 controller for error indications.
Verify EtherCAT device configuration and axis parameters within the KUKA HMI against the physical setup and documentation.
Perform a controlled cold start (power cycle) of the KR C4 controller to reset communication states.
