Product Description:

The CSH01.1C-PB-ENS-MEM-MA1-NN-S-NN-FW is an axis controller module manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted in an IndraDrive rack, the board supplies motion-control logic, fieldbus interfacing, and signal conditioning to coordinated servo drives. By processing encoder feedback, issuing setpoints, and forwarding status information to supervisory PLCs, it closes the control loop in automated packaging, printing, and material-handling cells. Designed for compact cabinets, it integrates power regulation and communication hardware on one card.

The controller draws a configured load of 19.5 W, so the backplane power supply can be sized with minimal thermal overhead. Its ENS section is powered from 11.6 V and consumes 300 mA during nominal operation, and this isolated rail feeds the incremental encoder inputs. Profibus networking is handled through a D-Sub 9-pin female connector and supports a data throughput of 12 MBaud, enabling fast cyclic exchange of position and diagnostic words. The MA1 analog channel digitizes feedback with 5 mV per increment and returns command voltages with the same 5 mV step size, providing symmetry between input and output scaling. Two probe inputs capture reference marks with an edge timing accuracy of 1 μs and accept pulses as short as 4 μs, allowing precise homing of linear scales.

I/O bandwidth is extended by the MEM interface, which streams position latches at up to 1 MHz over cables no longer than 40 m. When RS-232 diagnostics are preferred, the port transmits at a maximum of 115 kBaud across 15 m of shielded line. A form-C relay on the card can switch control signals or alarms up to 1 A. The MA1 driver can source up to 10 mA, which is enough for standard ±10 V actuators and reference devices. These limits help establish suitable wiring distances and signal loading for the installed controller.
