Product Description:

The CSH01.1C-PL-EN2-NNN-NNN-S1-S-NN-FW is a single-axis control section developed by Bosch Rexroth Indramat for the CSH Advanced Controllers series. The unit occupies one slot inside an IndraDrive power stack and supplies motion commands, feedback handling, and integrated safety logic to connected servo drives. As a control module, it coordinates motor position, velocity, and functional safety tasks in automated assembly lines, packaging machines, and material-handling systems. Its role is to manage the control functions that let the connected axis respond accurately to machine commands.

During steady operation the controller draws only 7.5 W, minimizing thermal load inside the cabinet. Command data are exchanged over a Parallel Interface, a hard-wired bus that delivers deterministic updates without protocol overhead. The module allocates a maximum encoder supply current of 350 mA, allowing it to energize high-resolution feedback devices without an external power rail. Position data are transferred through the EnDat 2.1 protocol, so the drive can access absolute position and electronic nameplate information over a single bidirectional line. For analog interpolation, the feedback channel also carries a 1 Vpp sine-cosine signal that improves fine positioning at slow speeds. Because the feedback path supports both digital and analog information, the controller can process detailed position data while maintaining smooth low-speed response. This combination supports absolute position reading and fine interpolation during motion.

At startup, the power rails deliver an inrush of 4 A for 100 ms; this short pulse precharges internal capacitors while remaining within common circuit-breaker tolerances. The parallel connector provides 16 inputs for status bits such as limit switches, and it also transmits actuator commands through 16 dedicated outputs that are logically isolated from the feedback path. This separation helps keep discrete control signals independent from the encoder channel during operation. Functional safety is handled through a 9-pin D-Sub socket that routes emergency-stop loops, and its solid-state driver can source up to 24 V / 0.5 A to external relays or contactors. That connection supports axis braking, power gating, and confirmation of safe-torque-off channels during fault conditions.
