Product Description:

The CSH01.1C-S3-ENS-EN1-MD1-NN-S-NN-FW belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. It is a compact motion and logic module intended to coordinate one drive axis inside larger IndraDrive systems. By running real-time control cycles, the unit links the higher-level PLC with the inverter section so that velocity, torque, and position commands reach the motor without delay in industrial automation cells.

This controller is configured for a Single-axis drive, which dedicates all internal processing to one motor channel for deterministic response. Field communication uses sercos III; this Ethernet-based bus moves cyclic data through an RJ-45 8-pin port and follows the IEEE 802.3 physical layer, allowing standard network cabling. The embedded sensor power rail provides 11.6 V at up to 500 mA, supplying incremental encoders or proximity probes without an external supply. Fast edge detection is supported because the TTL input stage can accept feedback pulses up to 400 kHz. A standard single-line control panel is mounted on the front for parameter entry and status viewing, and RS232 is present for commissioning tools.

The high-speed feedback connector delivers 8 V DC for HSF encoders, while resolver devices can be excited with 18.2 V p-p at 4 kHz, giving the drive several feedback topologies. The MD1 expansion adds 12 x 24 V digital inputs for limit switches and interlocks and 8 x 24 V digital outputs for contactors or signal lamps, reducing the need for separate I/O cards. Removable firmware and parameter sets can be stored in a MultiMediaCard (MMC) that fits the onboard slot, simplifying module replacement. No integrated safety technology is provided, so external safety relays must handle emergency-stop chains. Together, these electrical resources make the controller suitable for positioning tasks that require precise encoder support, rapid I/O reaction, and seamless sercos bus traffic without adding separate power supplies or gateway cards.
