Product Description:

The CSH01.1C-S3-EN2-EN2-MA1-NN-S-NN-FW is a motion-control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed inside IndraDrive power units, this section manages axis commands and processes feedback. It also exchanges real-time data with higher-level PLCs to coordinate multi-axis movement in automated machinery. Because command handling and feedback evaluation are combined in one section, the drive can react quickly to changes in machine motion.

The controller accepts differential analog signals through inputs that present 1000 kΩ of impedance and are digitized with a 12-bit converter, allowing moderate-resolution process monitoring without burdening upstream sensors. Two analog output channels source up to 10 mA each for valve or reference generation, while eight transistor outputs can sink a combined 500 mA for contactors or indicator lamps. Motion commands and diagnostic data move over the deterministic SERCOS III network so cycle-synchronous positions reach the drives within microseconds. The same board performs incremental or absolute position checking using EnDat 2.1, 1 Vpp, or 5 V TTL encoder formats, and it supplies the sensor interface with 350 mA at 5 V. This range of feedback support allows the controller to work with several common encoder signal types on the same platform. Output stages tolerate load resistances down to 35 Ω and can generate single probe pulses as short as 100 ms for position latching.

The logic core draws a base power of 7.5 W. Add-on slot 2 (EN2) requires a further 6 W, and the MA1 measurement module adds 2 W, so a 24 V supply can be sized accurately. Encoder electronics are held to 5.0 V with a permissible inrush of 4 A that must be accommodated by circuit protection. Internal timing hardware resolves capture events to 1 µs, supporting tight following error limits in high-speed pick-and-place gantries. That timing resolution also supports accurate position latching during fast, synchronized machine cycles.
