Product Description:

The CSH01.1C-PL-NNN-NNN-NNN-L1-S-NN-FW is an axis control card produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It plugs into compatible drive units and manages motion sequences through a built-in parallel logic section, providing position and velocity commands to servo inverters used in material handling, packaging, and printing machinery. Communication to upstream motion CPUs is handled by a parallel interface for deterministic data exchange.

The card’s analog front end accepts feedback signals against an input resistance of 160 kΩ, while its two voltage-scaled outputs can drive loads down to 5 kΩ for reference generation. Each output is built on an 8-bit converter that changes by 19.5 mV/inc, and the total converter width is 8 bit, giving predictable resolution during closed-loop control. Electronics on the board draw a steady 7.5 W from the host supply, so cabinet thermal design can be calculated accurately. The section also contains seven discrete inputs, four shared digital I/O points, and a maximum command pulse length of 100 ms for timed events. Two onboard analog outputs and the combined digital resources allow direct sensor reading and actuator triggering without external expansion. A 100-µs base cycle supervises scaling so that position data remain synchronous with velocity loops.

For higher-level machine interaction, the parallel logic area provides 16 dedicated input lines and 16 transistor outputs that exchange status bits with external PLC racks. A startup current limit of 4 A protects backplane conductors during power-up, and emergency actions meet the requirements of Category 0 stop when the L1 safety pin is asserted. Field wiring terminates on a D-Sub 9-pin female connector. Starting-lockout circuitry prevents unintended energizing of the connected drive axes until all interlocks are cleared, maintaining compliance with plant safety directives.
