Kuka · KR C4 extended
This fault indicates an issue detected by the brake cable monitoring device, signaling a short-circuit, overloading, or a break in the brake connection, or that no brake is connected. This compromises the safety function of the motor brake, potentially leading to uncontrolled axis movement or dropped loads.
Click steps to track your progress.
Check brake voltage at the brake terminals (note if fault occurs in all axes).
Measure the motor brake resistance for opens or shorts.
Check brake cable and motor cable for damage, continuity, and proper connections.
Reinitialize the drive bus: Power Off / Power On.
Check KSP module for faults related to brake control.
