Product Description:

The CSH01.1C-SE-EN2-EN1-MD1-S1-S-NN-FW is a motion-control option card built by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in a Rexroth drive rack, it executes axis control algorithms, manages real-time fieldbus traffic, and allows the connected power section to drive servomotors with synchronized torque and position profiles. By combining fast logic processing with networked communication, the card provides the local control needed for coordinated industrial automation.

I/O resources on the board include 12 x 24 V digital inputs for limit switches or sensors and 8 x 24 V digital outputs for actuator signals, so machine states can be captured and reacted to within one scan. Startup demands are moderated by a 4 A inrush current limiter, after which continuous draw stays near 7.5 W, easing power supply sizing inside compact electrical cabinets. Command data moves over SERCOS II, and the controller can negotiate transfer rates up to 16 MBaud, ensuring deterministic update cycles even when multiple axes share the ring. Encoder channel EN2 is powered with a regulated 5.0 V rail at 350 mA, while channel EN1 allocates 8 V and a high-speed-frame current of 250 mA; both supplies are isolated to protect low-level feedback lines from switching noise.

Position feedback options span incremental TTL, sine-cosine, and the EnDat 2.1 / 1 Vpp / 5 V TTL protocol, allowing the controller to work with different feedback formats. A built-in analog output rated at 5 V / 1 mA can stream diagnostic parameters such as torque demand to external monitors. For functional safety, the card routes status through a Safety Technology I/O gateway and energizes interlock relays with a protected 24 V / 0.5 A output. This arrangement supports safe stop or speed-limited operation without extra modules.
