Product Description:

The CSH01.1C-PB-ENS-EN1-EN2-L2-S-NN-FW is a plug-in motion and safety controller manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in a drive rack, the unit supervises servo position loops, evaluates encoder feedback, and exchanges data with higher-level PLCs so that coordinated motion can be added to packaging lines, assembly stations, or material-handling cells. By combining encoder evaluation, fieldbus networking, and integrated safety circuits in one card, it reduces cabinet space and simplifies system wiring within industrial automation cells.

At the application layer, the controller communicates over PROFIBUS. This interface runs at up to 12 MBaud, allowing timely cyclic and acyclic telegrams between the drive and supervisory PLCs. The logic section draws 7.5 W of base power, a low consumption figure that helps minimize panel heat load in multi-axis systems. For machine safety, a hardware channel implements Safe Torque Off, which disconnects gate drives inside the power module when triggered. The STO inputs accept a 24 V signal at 3 mA, so standard safety relays or light curtain outputs can energize the circuit without additional drivers.

Its housing measures 49.5 mm wide, 241 mm high, and 103 mm deep, permitting dense stacking alongside other drive sections while still leaving clearance for airflow. During power-up, the card admits an inrush current of 4 A, which must be considered when sizing auxiliary supplies. The functional safety architecture is rated SIL3 / Cat. 3 PL e, enabling use in applications that require controlled stop performance without external contactors. Encoder sockets provide 5.0 V for EnDat feedback on X10, 11.6 V for IndraDyn or HIPERFACE signals on X4, and differential lines for HSF/RSF formats on X8, so multiple sensor types can be connected through one controller board.
