Product Description:

The CSH01.1C-S3-ENS-EN2-MD2-NN-S-NN-FW is an automation controller module built by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. Within a modular drive cabinet, it handles the logic and motion tasks for servo axes, coordinating parameter handling, fieldbus exchange, and diagnostic feedback. The unit slots onto a power section and serves as the central processor in machine tools or packaging lines where deterministic motion sequencing is required.

This configuration features 2 analog outputs that can deliver reference values or feedback signals to external drives or process instruments. For discrete sensing, it provides 7 dedicated inputs that allow direct wiring of limit switches or start-of-cycle contacts without extra I/O boards. Motion data from auxiliary axes can be captured because the MD2 expansion grants 16 input points and 16 output points, enabling synchronized handshakes with peripheral actuators. Axis position and velocity commands are exchanged over the controller's master channel, which uses SERCOS III, so cyclic data are transferred with microsecond-level jitter even when multiple stations share the ring.

Network wiring to the S3 interface uses 100Base-TX signaling through an RJ-45, 8-pin connector, letting standard Ethernet cables handle the real-time telegrams while meeting electrical isolation rules for motion systems. Two internal supply rails power the option cards; the EN2 encoder interface is held at 5.0 V, a level suitable for TTL or LVDS sensors, whereas the ENS channel for safety-related encoders is maintained at 11.6 V to support higher-power transducers. Because these voltages and the associated currents are delivered by the controller backplane, no external DC supplies are needed, which simplifies cabinet wiring and helps the feedback circuits retain regulated power during fieldbus resets.
