Product Description:

The CSH01.1C-SE-EN1-NNN-MD1-S2-S-NN-FW is a plug-in motion control unit from Bosch Rexroth Indramat that belongs to the CSH Advanced Controllers series. Installed in IndraDrive platforms, it supervises servo axes, coordinates interpolation, and relays status data to higher-level PLCs. By combining encoder evaluation, I/O handling, and network communication on a single board, it serves as an axis controller in packaging machines, material-handling cells, and similar industrial automation lines.

At base load the card consumes 7.5 W, so ventilation demands stay minimal, yet the power supply must provide headroom for the startup draw of 4 A. All drive commands pass through the SERCOS II ring, and the device supports a minimum cycle time of 1000 µs to maintain precise velocity control on high-speed tooling. One analog input acquires a reference such as tension or torque, while two analog outputs can modulate proportional valves. The integrated MD1 module provides 12 x 24 V inputs for limit switches and 8 x 24 V outputs for contactors, and Option 3 can add extra digital points. Individual output pulses may be extended to a 100 ms width so slower field devices switch reliably.

Encoder channel EN1 operates sin-cos transducers with AC 18.2 Vpp and supplies their electronics with DC 8 V, ensuring compatibility with the MHD and MKD motor families. Control electronics, Safe Motion processors, and the MD1 stack draw power from an isolated DC 19.2–30 V rail, which helps protect low-voltage logic during DC-bus transients. The integrated safety layer supports Safe Motion functions, allowing machinery to decelerate or hold position under fault conditions without external relays. Process data leave the card over fiber-optic SERCOS links, so electrical noise on motor cables does not affect network timing.
