Kuka · KR C4 Operating Instructions

What does 26111 mean?

An overtemperature condition has been detected within the KPP or KSP device for a specific axis. This indicates that the internal operating temperature of the drive or control unit has exceeded its safe limits, potentially due to insufficient cooling or excessive load. Continued operation in this state can lead to component damage or premature failure.
