Product Description:

The CSH01.1C-S3-ENS-NNN-MEM-L2-S-NN-FW controller is produced by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. This single-axis master module coordinates servo drives and peripheral devices in industrial automation cells, translating motion commands into synchronized electrical signals for accurate axis behavior. By integrating communication, encoder handling, and safety functions on one card, the unit reduces cabinet space and wiring while providing stable control for packaging, material handling, and assembly lines. Its role is to serve as the central control layer for a drive-based axis where motion response and signal timing must remain consistent during operation.

The control side presents 1 analog input for sensor feedback and 2 analog outputs that can be mapped to proportional valves or speed references. Network traffic is routed through a RJ-45 8-pin connector, supporting SERCOS communication over optical or copper rings. The real-time channel is SERCOS III, which supports very fast cyclic data exchange together with integrated safety telegrams. For position feedback, the board carries a standard encoder evaluation circuit that supplies encoders with 11.6 V at up to 500 mA, eliminating the need for external power taps and helping maintain stable signal quality on longer cable runs.

For encoder-normalized signal wiring, the reference cable may reach 50 m without sense conductors or 75 m when sense conductors are used, giving more flexibility for larger machine layouts. Power consumption remains low because the ENS circuitry draws 6 W, while the memory module and safety section add only a small additional load inside the cabinet. One normally open relay contact can pass status information to higher-level controls, an optional encoder emulation module can mirror position data for legacy drives, and Safe Torque Off disables drive power when the functional safety channel is triggered. These features allow the controller to support both modern servo communication and integration with surrounding machine hardware.
