Product Description:

The CSH01.1C-S3-EN1-NNN-MA1-L1-S-NN-FW is a single-axis controller module built by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Within an automation cabinet, it manages drive tasks by generating motion commands and forwarding real-time status to higher-level PLCs through its integrated fieldbus interface. This module forms the control layer between a servo drive and a motion application, converting program data into precise electrical and communication signals required for industrial machinery. Because it is a single-axis module, it is suited to applications where one motion channel must be coordinated with a broader machine control system.

The unit provides 2 differential analog inputs with a resolution of 12-bit, allowing the controller to resolve 4096 discrete levels for closed-loop scaling and reference processing. Two analog outputs use the same resolution and leave the module through the D-Sub 15 female analog connector. This arrangement supports external reference devices and analog monitoring points without extra conversion hardware. Command traffic to the drive is exchanged over SERCOS III, accessed through a RJ-45, 8-pin port, so the controller can operate on a deterministic real-time Ethernet network across multiple axes. Digital enable arrives as a 24 V / 3 mA control signal, and machine status can be routed to external relays through a ready contact rated at DC 24 V / 1 A.

For feedback handling, the first encoder interface supports Resolver or HSF signals and supplies the transducer with 18.2 Vpp for the excitation windings plus 8 V DC for electronics, eliminating the need for an external sensor-side power rail. Start-of-cycle interlocks are implemented through the integrated safety function Starting lockout, which is wired on a D-Sub 9 female safety connector so motion permission can be supervised by certified circuitry. Diagnostic access is available through the RS232 serial port, allowing parameter viewing and local communication without occupying the real-time network. The dedicated service connection keeps setup traffic separate from cyclic drive communication.
