KUKA KR C5 slim-2 Robot Controller

The KUKA KR C5 slim-2 Controller is a controller platform designed for small robots, compact workstations, and cabinet slide in installations. It supports up to 6 servo axes, weighs approximately 18 kg, has a protection level of IP20, noise level below 71 dB (A), power supply of AC 3 × 380 V, 400 V, 415 V, 440 V or 480 V, three-phase four wire, grounded neutral point, allowable deviation ± 10%, rated connected load 5.00 kVA, system impedance not greater than 300 m Ω, ground leakage current not greater than 150 mA, line side fuse minimum 3 × 10 A, maximum 3 × 16 A slow melting, frequency 49 to 61 Hz, thermal output 440 W. For on-site engineers, the difficulty of KR C5 slim-2 lies not in "wiring power on", but in the coordination between control unit and power unit, default allocation of safety interface, The logic of load voltage for USS 2, the replacement sequence of sliding in modules, and how to quickly locate faults from the power supply, safety chain, communication chain, and cooling chain. This article focuses on maintenance and troubleshooting.
