Product Description:

The CSH01.1C-PB-EN2-NNN-MD2-L1-S-NN-FW is an axis controller module produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed in IndraDrive automation platforms, the unit acts as the processing core that converts fieldbus commands into real-time drive signals, coordinating servo axes and safety interlocks on production machinery. Its role in industrial automation is to provide programmable motion control with a direct interface to higher-level PLCs, enabling synchronized positioning, velocity regulation, and application-specific logic across packaging, assembly, and material-handling systems.

The controller’s power section draws only 7.5 W, which helps limit cabinet heat while the drive idles. It exchanges position data and diagnostics over PROFIBUS-DP at up to 12 Mbit/s, allowing fast communication with the control network. The EN2 channel can supply 350 mA at 5 V to encoders, and its sine inputs use a 120 ohms termination that helps preserve signal quality on long cables. For incremental formats, the square-wave track handles up to 1000 kHz, covering very fast spindle or linear motor feedback. A single-line display on the front panel shows status and node address during setup.

The module supports the EnDat 2.1 / 1 Vpp / 5 V TTL interface, so one hardware port can work with absolute, analog, or incremental encoders. Logic processing on the MD2 expansion provides 16 opto-isolated input points and an equal number of transistor outputs, allowing the controller to manage local limit switches, valves, and relays without remote I/O racks. The internal PB communication ASIC draws only 2 W, so the overall power budget remains modest even when encoder and I/O functions are active. A built-in starting lockout circuit keeps the drive disabled until emergency-stop loops and wire-break checks are verified.
