Product Description:

The KCU02.1N-ET-ET-025-NN-N-NN-NW is a cabinet-mount control unit manufactured by Bosch Rexroth Indramat for the KCU IndraDrive Control Systems series. Intended for multi-axis automation, the module concentrates power distribution, safety inputs, and fieldbus connectivity for several IndraDrive power sections. It serves as the point where hybrid motor cables, emergency-stop chains, and control-voltage supplies enter the cabinet, which helps simplify panel layout in transfer lines, palletizers, and handling gantries. By combining communication and safety circuits in one enclosure, it reduces cabinet complexity and shortens setup time. This arrangement also centralizes control wiring so adjacent power sections can share common interfaces instead of requiring separate cabinet hardware.

The controller exchanges real-time motion and diagnostic data through its Multi-Ethernet interface, so a single port supports EtherNet/IP, PROFINET, and EtherCAT without extra option cards. Because the network port is universal, the same control unit can be integrated into different plant communication standards without changing the cabinet layout. Under rated conditions, the internal supply draws 25 A, which indicates how many converters can be energized before an external feeder is needed. A depth of 252 mm leaves clearance behind standard 300 mm control cabinets, while a front width of 50 mm saves rail space for adjacent automation hardware. The unit can coordinate up to 20 drive units by forwarding synchronized bus and safety signals, which helps keep response timing consistent across connected axes.

The unit supports a 200 m hybrid cable reach, allowing remote motor islands to operate from a single cabinet location. The housing weighs 3.8 kg, which keeps mounting manageable, and its height of 352 mm fits cabinets that use 400 mm wiring channels. A dedicated Hybrid Cable Connection carries DC power, encoder feedback, and communication conductors in one link, which reduces cable count and simplifies routing between the cabinet and the machine. Integrated DC-bus fuses help isolate short-circuit faults, while the module bus, control-voltage, and emergency-stop inputs allow parallel drive chains to enter safe torque-off at the same time. Centralized fault isolation also helps keep disturbances confined to the affected branch instead of spreading across the full drive group.
