Product Description:

The CSH01.1C-PL-EN1-EN2-EN2-NN-S-NN-FW belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. This single-axis control card interfaces between IndraDrive power sections and external machine logic, providing position and velocity processing for servo applications in packaging, printing, and general automation. It occupies one slot in a modular drive stack, where it manages encoder feedback, analog scaling, and field wiring while the power section handles the motor’s high-current switching.

The card issues an analog command signal of 5 V / 1 mA with an effective resolution of 19.5 mV/inc, enabling fine torque or speed trimming from the drive. Its En1 encoder port sources 8 V to incremental transducers, and the second encoder channel accepts EnDat 2.1, 1 Vpp, or 5 V TTL formats with a separate encoder supply. Parallel machine I/O is presented on a 37-pin D-Sub that carries 16 optically isolated inputs and 16 transistor outputs, and each output is limited to 1000 mA. An RS-232 service link is provided through an 8-pin Mini-DIN connector and supports a maximum transfer rate of 115 kBaud, allowing parameter transfer and trace capture without occupying the main control bus.

The controller’s internal electronics draw 7.5 W from the common backplane, and a soft-start circuit limits inrush current when the rack energizes. Input lines register a logical high once the external driver supplies 15 V, which helps maintain noise immunity in industrial cabinets. Output drivers maintain a guaranteed ON pulse no shorter than 100 ms, a duration suitable for most valve or relay coils. Additional safeguards include a supply for the secondary encoder, pulse-width-conditioned outputs, and RS-232 wiring that remains isolated from the power stage to preserve signal integrity during high-frequency switching events.
