Product Description:
The CSH01.1C-NN-ENS-NNN-NNN-L2-S-NN-FW is a single-axis control card produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It slides into IndraDrive power sections to provide command processing, analog acquisition, and safety supervision for servo axes used in packaging machines, handling modules, and processing centers in automated systems. By combining analog, digital, and serial channels on one board, the unit converts field-level signals into drive-ready data, manages motion sequences, and can remove power to the drive stage through its integrated safety circuit when faults are detected.
The analog front end accepts feedback across a bandwidth of 1.4 kHz; this limit indicates the fastest signal fluctuation that can be captured without distortion. Its differential input path presents an impedance of 160 kΩ, minimizing loading on external sensors. Each conversion step is quantized at 1.23 mV/inc, while outgoing reference values are generated with a granularity of 19.5 mV/inc for proportional valve or drive control. The digital input circuitry recognizes a logical ON state once line voltage reaches 15 V, ensuring immunity to lower-level noise. Standard encoder evaluation further supports deterministic position capture during closed-loop operation.
The card delivers a per-channel sink capability of 500 mA, and the ENS safety rail carries the same rating; a combined group limit of 1000 mA prevents PCB overheating when several outputs are energized simultaneously. Probe inputs detect edge transitions as short as 4 µs, and the accompanying ENS track works up to 400 kHz to accommodate high-resolution encoders. Safe Torque Off is implemented in hardware, eliminating power to the drive stage without relying on software. Serial diagnostics travel over an RS232 port, reach 115 kBaud, and can be extended up to 15 m with the recommended cable. Control-bus hardware is omitted, so communication must occur locally through the available interfaces.
