Product Description:

The CSH01.1C-S3-NNN-NNN-NNN-L2-S-NN-FW is a single-axis motion controller module produced by Bosch Rexroth Indramat for integration into drives in the CSH Advanced Controllers series. Within an automation rack, this unit supplies command processing and network interfacing so IndraDrive power stages receive deterministic motion profiles. The product acts as the central logic element, translating high-level machine instructions into drive-level torque and speed commands needed for coordinated multi-axis work cells and synchronized machine functions.

Communication is executed over SERCOS III, carried on an RJ-45 eight-pin port that supports real-time cyclic data exchange. There are 11 digital inputs for sensor feedback, while 4 digital outputs can energize field devices, and each output channel tolerates up to 500 mA of sink current. The controller draws only 7.5 W during steady operation from a 24 V DC source and tolerates an inrush of 4 A at power-up. Internal timing logic caps command pulses at 100 ms, protecting actuators that cannot process longer activation windows. Two differential analog inputs present a resistance of 160 kΩ so upstream transducers are not heavily loaded, and each analog output can source 1 mA for valve or potentiometer positioning. A relay contact rated at 24 V DC and 1 A is also provided for fault signaling, and the module’s digital bus is supplemented by an RS-232 maintenance link.

The RS-232 service port reaches 115 kBaud over cable runs up to 15 m, allowing direct access to local service functions without occupying the main network. Integrated safety is delivered through Safe Torque Off, and the associated wiring terminates at a D-Sub, 9-Pin Female connector so emergency loops remain separate from standard I/O. SERCOS cycle synchronization keeps analog channels and digital signal changes aligned with network events and the internal position loop, which supports predictable machine response during coordinated motion.
