Product Description:

The CSH01.1C-S3-EN2-EN2-NNN-NN-S-NN-FW is a compact motion-control section manufactured by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed beside a power module, it issues velocity, torque, and position commands to a connected drive in automated machining, packaging, or material-handling equipment. Acting as the logic layer between a plant-wide network and the drive hardware, it concentrates signal conditioning, axis monitoring, and real-time communication functions in one removable card.

It accepts differential analog feedback over an input span of ±10 V, allowing external potentiometers or process transducers to trim setpoints. The module mirrors calculated values on an auxiliary output that can source 1 mA at a fixed 5 V level, supporting chart recorders or field indicators. Internal electronics draw only 7.5 W, so cabinet heat rise is minimal. Real-time data exchange occurs on a Sercos III ring through an 8-pin RJ-45 jack, providing the deterministic timing needed for interpolated motion. Mechanical depth is limited to 49.5 mm; together with a 103 mm width, this enables high-density stacking on DIN rails. The gating circuit can issue control pulses up to 100 ms wide, matching the response time of standard Bosch Rexroth power stages.

For position feedback, the card offers a D-Sub 15-pin encoder socket that supplies up to 350 mA at 5 VDC to an EnDat 2.1, 1 Vss, or TTL transducer. Two identical channels are present, so dual-loop systems can be wired without splitters. The enclosure stands only 241 mm tall, facilitating placement in shallow panels while retaining adequate airflow above heat-producing neighbors. During startup, the logic absorbs an inrush of 4 A, so supply breakers must be sized for that short surge. Regulated 5 V encoder power is maintained by an internal switch-mode converter that remains stable across the full 350 mA load range.
