Product Description:

The CSH01.1C-S3-EN1-EN2-MD1-L2-S-NN-FW belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. This controller coordinates one servo axis inside an automation cell by exchanging motion commands and feedback with a drive module. Within the overall system architecture, the unit performs path generation, I/O processing, and safety monitoring so that deterministic control functions can be integrated directly at the drive level. This arrangement keeps time-critical axis control close to the drive and supports stable motion response during operation.

Command and status data are transported over the SERCOS III real-time bus, with an integrated 8-pin RJ-45 connector serving as the physical link. On the machine side, the digital extension terminals provide 12 digital inputs and 8 digital outputs, and each output can switch up to 24 V / 0.5 A. For analog signaling to external measurement devices, the controller includes a 5 V, 1 mA channel. It also carries two encoder supply rails, with 8 V available for the first feedback path and 5 V available for the second, so connected sensors receive the required excitation voltage.

The first encoder port accepts resolver or HSF feedback, and the second port accepts EnDat 2.1, 1 Vpp, or 5 V TTL signals, allowing the controller to process high-resolution position data from several common feedback types. Safety is handled through the integrated Safe Torque Off function on a D-Sub 9-pin female connector, and the acknowledge channel can sink 24 V DC / 1 A. Network communication follows the IEEE 802.3 Ethernet standard, so standard infrastructure can be used for diagnostics and service access. Because the hardware is designed for a single-axis application, all resources are dedicated to one drive, which simplifies setup and supports deterministic response during motion and safety events.
