Product Description:

The CSH01.1C-S3-EN2-MA1-MD2-NN-S-NN-FW is a single-axis motion controller built by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive power section, it supplies real-time axis regulation and application logic for packaging machines, pick-and-place stages, and general material-handling cells. By combining communication, feedback processing, and local I/O on one card, the controller reduces cabinet wiring while maintaining deterministic coordination of the attached drive and machine sensors.

Continuous power consumption is limited to 7.5 W, so thermal load on the drive rack remains low. Command exchange with drives and PLCs occurs over SERCOS III, giving cycle-synchronous data transfer for velocity and torque loops. The encoder interface accepts EnDat 2.1, 1 Vpp sine-cosine, or 5 V TTL signals, letting the card evaluate high-resolution feedback without an external converter. Power-up transients are limited because inrush current peaks at 4 A and the surge lasts only 100 ms, which helps protect upstream fusing and minimizes voltage dip on the 24 V control bus. Two analog channels on the MA1 board provide 0 to 10 V or ±10 V command scaling, and programmable filtering suppresses noise on small-signal inputs.

The MD2 expansion adds 16 digital inputs and 16 sourcing outputs rated at 24 V, 0.5 A, plus integrated SSI evaluation for absolute encoders used in gantries or linear axes. Internal calculations use 12-bit resolution on the analog pair, and the card can source a reference or bias through an onboard analog output of 5 V, 1 mA. Parameter sets and diagnostics are accessible locally through the front-mounted standard control panel or remotely through the serial link designated as RS232. Because the controller contains no dedicated safety technology, external safety relays or PLC variants must handle emergency-stop and guard-monitoring functions when the module is installed.
