Product Description:

The CSH01.1C-S3-ENS-EN2-EN2-S2-S-NN-FW is a single-axis control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Acting as the command layer inside IndraDrive drives, the unit executes position, speed, and safety routines for servo axes used in packaging, handling, and processing equipment. It interfaces with power sections through an internal backplane and supervises drive feedback, I/O, and network data to coordinate closed-loop motion sequences. Its compact format allows installation on DIN-rail-mounted drive stacks inside electrical cabinets.

At the hardware level, the control section draws a base power of 7.5 W, which helps limit heat rise inside the cabinet. Command and parameter data travel over SERCOS III, giving deterministic cycle times for multi-axis synchronization. The integrated ENS analog converter operates at 12 bit resolution, so each channel outputs 4096 discrete values for speed reference or torque limitation. Ethernet wiring enters through an S3 interface rated to 100Base-TX, which fits standard CAT5e cabling for plant networks. For service diagnostics, the unit maintains a serial channel selectable up to 115 kBaud, allowing diagnostic tools to access trace data without occupying the real-time bus.

The EN2 I/O segment supplies up to 350 mA at 5.0 V for encoder evaluation or small sensor loads, while the separate ENS rail delivers 11.6 V to the internal converter stages. Each digital output can switch 0.5 A, letting the controller actuate contactors, brake relays, or stack-light indicators directly. The analog output voltage is 5 V, which supports external speed setters, and the digital inputs accept 3 mA to match PLC sourcing cards. An EN2 load resistance limit of 35 Ω and an ENS input resistance of 120 Ω help protect the channels from overload. Safe Motion functionality uses dual-channel logic for stop and monitoring functions, with connection through an RJ-45 8-pin port.
