Kuka · KR C4 extended
This fault indicates that an axis is overloaded, leading to the mean continuous current being too high. It can occur during start-up due to excessive program load or during operation due to system modifications, temperature influences, or excessive power demand. The risk is potential damage to the KPP/KSP power units or the axis motor due to sustained high current.
Click steps to track your progress.
Reinitialize the drive bus: Power Off / Power On.
Check the machine for mechanical issues causing high load.
Check trace recording of axis current to identify load patterns.
Adapt program velocity to reduce instantaneous load.
Check CBS pressure (if applicable to the machine configuration).
Check gear unit for excessive friction or damage.
