Product Description:

The CSH01.1C-PL-EN2-MA1-MD2-S1-S-NN-FW is a control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed inside IndraDrive power stages, it manages axis command processing, encoder evaluation, field I/O, and the built-in safety modes Standstill, Interlock, Reduced Speed, and Direction. By combining signal conditioning, motion algorithms, and safety monitoring in one slot, the unit streamlines drive integration in industrial automation cells where space and wiring economy are critical.

The analog interface accepts input and generates output in the range of ±10 V, and its conversion depth of 12 bit provides 4096 discrete steps for each channel, allowing proportional speed or torque references with moderate resolution. Internal power consumption is 7.5 W, so thermal loading in densely populated control cabinets remains limited. Physical size is 241 × 49.5 × 103 mm, which permits side-by-side mounting on DIN rails without exceeding typical enclosure depths. When EnDat cabling is used, the EN2 interface supports sense-line runs up to 75 m; this distance helps maintain feedback integrity for motors mounted on large gantries or conveyors. Additional resources include a single-line display for local diagnostics, an EnDat 2.1 / 1 Vpp / TTL encoder input, and master communication through a parallel bus.

The encoder supply outputs 5 VDC at up to 350 mA for compatible feedback devices. For process variables, module MA1 provides 2 In / 2 Out analog points, while digital tasks are handled by PL with 16 DI / 16 DO. Signal exchange with the drive stack or an external PLC is routed through a D-Sub 37-pin connector that mates directly with standard ribbon harnesses. An auxiliary 24 VDC supply is present for SSI encoders, allowing mixed-protocol feedback to coexist on the same axis without extra power supplies.
