Product Description:

The CSH01.1C-S3-ENS-EN1-NNN-S1-S-NN-FW control section is a modular hardware unit built by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It mounts on an IndraDrive power module and handles axis computation, encoder evaluation, and safe I/O so that servo drives, inverters, and peripheral sensors can be synchronized in automated assembly lines, packaging machines, or material-handling stations. This arrangement places motion control and signal processing in the same drive assembly, which helps keep the installation compact and organized inside the cabinet.

An analog monitor channel delivers 5 V, 1 mA, allowing process meters or oscilloscopes to track internal variables without overloading the source. Signal granularity on that channel is fixed at 19.5 mV/inc, which is the smallest voltage step available on the monitor output. Field devices such as light curtains or position switches are accepted on digital inputs rated for 24 VDC, 3 mA, and the controller can drive contactors or indicator lamps from digital outputs that source up to 24 VDC, 0.5 A. When higher-current loads must be energized after self-test, the ready relay provides a separate line that closes at 24 VDC, 1 A, isolating safety-related power distribution from low-level logic signals.

Supporting these interface channels, the board draws only 7.5 W during steady-state operation and tolerates an initial surge of 4 A when the drive rack is first energized. The compact housing stands 241 mm tall, with a narrow width and moderate depth that support high-density cabinet layouts while still leaving room for its D-Sub 9 female safety connector and dual feedback ports. Motion commands and diagnostic data move over the deterministic SERCOS III master link, so multiple drives can be phase-aligned without separate timing hardware. The combination of low operating power, compact packaging, and integrated communication supports continuous use in coordinated multi-axis systems.
