Product Description:

The CSH01.1C-ET-EN1-NNN-NNN-L2-S-NN-FW is a motion-logic control card from Bosch Rexroth Indramat, supplied within the CSH Advanced Controllers series. Installed in IndraDrive power sections, the card executes axis control, fieldbus handling, and integrated safety for servo and spindle tasks in automated machinery. By combining resolver feedback, high-speed interfaces, and multi-protocol Ethernet, the unit coordinates real-time positioning with higher-level PLC or SCADA systems while keeping wiring concentrated on a single plug-in module. This arrangement lets one controller manage closed-loop motion and machine communication without requiring separate external control hardware for each axis.

The card receives differential process signals through an analog input span of ±10 V, and its input impedance of 160 kΩ minimizes loading on upstream transducers. Commanded motor currents or tension loops can be issued on the dedicated analog output that sources 5 V / 1 mA. Digital machine states enter through opto-isolated inputs rated at 24 V / 3 mA, while contactors and pneumatic valves can be driven directly by outputs scaled for 24 V / 0.5 A. These electrical channels allow the control card to exchange velocity setpoints, sensor levels, and interlocks without external I/O boards, reducing cabinet space and bus latency. The available I/O is suitable for direct connection to common sensors, switches, and actuating devices around an individual machine axis.

Fine reference generation is achieved with an analog output step size of 19.5 mV/inc, matching the internal 12-bit converter granularity. Network traffic moves through a copper link conforming to 100Base-TX and routed by the Multi-Ethernet stack, so EtherNet/IP, PROFINET, and EtherCAT can be selected in software. Core electronics draw 7.5 W, while the En1 and Et option channels add 6 W and 2.2 W respectively, which is useful for cabinet thermal calculations. An on-board 24 V / 1 A relay provides galvanically separated signaling to field devices. Resolver excitation of 18.2 Vpp at 4 kHz is supplied for either standard resolvers or HSF feedback, enabling absolute position evaluation without external modules. Functional safety is embedded through the certified Safe Torque Off circuit, which removes drive power to the motor in less than a millisecond when the safety chain is opened.
