Product Description:

The CSH01.1C-CO-ENS-NNN-MD1-S2-S-NN-FW belongs to the CSH Advanced Controllers series manufactured by Bosch Rexroth Indramat. The module serves as the command layer for electric drives, accepting fieldbus instructions and translating them into finely scaled current, voltage, and encoder references. Within an automation cell, it synchronizes multiple axes, processes status feedback, and distributes enable signals, so machine builders can integrate coordinated motion without adding separate PLC hardware. Its compact format allows direct mounting in the drive stack, minimizing cabinet depth and wiring complexity on high-density production lines. Because control functions are integrated into the drive assembly, signal paths stay short and response remains consistent during coordinated motion.

The analog interface is designed with an input resistance of 160 kOhm, preventing excessive loading of upstream sensors. Each voltage output can source up to 1 mA and reaches a calibrated level of 5 V, enabling reference signals for external amplifiers. Internally, the controller dissipates a base power of 7.5 W during idle logic operation, supplied through a dedicated bus that delivers a nominal 24 V DC. When this supply is first applied, the circuitry draws an inrush current of 4 A for 100 ms, after which consumption drops to its steady values. This start-up surge must be considered when sizing secondary fusing and power-sequencing relays. Steady-state consumption remains suitable for logic supply circuits that also support other low-power control electronics.

The communication section marked CO uses a five-pole connector, so field wiring is completed through 5 terminals; the companion CO module itself adds only 1 W of dissipation, and its clamps are tightened to 0.5 Nm. The ENS encoder header supplies 500 mA at 11.6 V, and the ENS logic accounts for 6 W of the overall heat load. Twelve optically isolated digital inputs interface with sensors, while eight push-pull outputs drive actuators on the MD1 sub-board. A form-C relay is also provided and may switch up to 1 A for interlock or fault-indication lines. The isolated I/O channels allow switches, sensors, and status contacts to connect directly to the control section in many layouts.
