Product Description:

The CSH01.1C-S3-EN2-ENS-MD2-S1-S-NN-FW is a motion-control card produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. As a compact controller board, it governs a servo drive from within the IndraDrive platform and handles real-time trajectory processing, position feedback, and field-level safety. Installed in cabinet drive racks, it acts as the central logic layer that translates program commands into precise motor motion for automated assembly lines, packaging equipment, and handling systems in industrial automation applications.

At the motion layer, the board supports a single-axis configuration, so it supervises one drive channel per card. Command and diagnostic data are exchanged over SERCOS III, providing deterministic Ethernet cycles for synchronized multi-device networks. For position feedback, the primary interface accepts EnDat 2.1, 1 Vpp sin-cos, or 5 V TTL signals, while the secondary EN2 channel powers encoders with 5.0 V and can source up to 350 mA. This mix allows the controller to read high-resolution absolute encoders and incremental transducers without external converters, ensuring accurate interpolation and electronic nameplate support.

The ENS channel, reserved for standard encoder evaluation, has a 12-bit analog-to-digital width, giving sufficient resolution for fine incremental counting on resolver-based feedback. Its supply rail delivers 11.6 V with a load capacity of 500 mA for sensors that require higher excitation than the EN2 port. The integrated MD2 module furnishes 16 digital inputs and an equal number of outputs, each switched through low-side drivers that can sink up to 0.5 A, enabling the direct actuation of relays, valves, or light curtains. A dedicated Safety Technology I/O bus, a single-line operator panel, and an internal SSI-capable I/O extension complete the functional set without adding extra wiring complexity.
