Product Description:

The Bosch Rexroth Indramat CSH01.1C-PL-EN1-EN2-NNN-NN-S-NN-FW belongs to the CSH Advanced Controllers series. Installed on an IndraDrive control rack, this card coordinates axis motion, feedback, and local I/O for machinery such as pick-and-place units, printing presses, and carton formers. It forms the interface layer between drive inverters and plant-level PLC commands, allowing deterministic position loops and high-speed data exchange without separate gateway hardware. This arrangement also lets one module manage command exchange and feedback handling within the same drive platform.

The analog front end has an impedance of 160 kΩ, so connected transducers are not significantly loaded, and it accepts a ±10 V command span for speed or torque references. A 1 mA, 5 V driver is available for potentiometer or LVDT excitation. Control electronics are fed by a regulated DC 24 V rail, while discrete outputs share a 1.1 A sourcing channel that can power proximity switches and relay coils. The EN2 socket supplies 5.0 V DC at 350 mA and supports EnDat 2.1 / 1 Vpp / TTL feedback, giving the system flexibility to use either digital or analog encoders. Initial energization draws a 4 A inrush that must be considered when selecting cabinet fusing. HSF/RSF is available for the first encoder, and the parallel interface master link transfers position words to upstream controllers with minimal latency.

The board occupies 103 mm of rack width, extends only 49.5 mm behind the mounting plane, and rises to 241 mm, so multiple controllers can sit side by side while maintaining rear airflow. Input-capture hardware accepts pulse widths up to 100 ms, accommodating slower mechanical limit switches or optical marks without missed counts. Its shallow depth also helps when the rack is installed in compact cabinets with limited door clearance. These dimensions and timing allowances support layout planning for wiring paths, duct routing, and signal conditioning around adjacent drive components.
