Product Description:

The CSH01.3C-PB-ENS-EN1-CCD-L2-S-NN-FW is a control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive power module, it serves as the central processor that issues motion commands, interprets feedback, and manages safety for machines that require precise electronic gearing, camming, or positioning. The card is intended for industrial automation cells where rapid data exchange with a plant-level PLC and direct encoder processing are needed to coordinate one servo axis with conveyor lines, pick-and-place arms, or indexing tables.

This controller supervises a single-axis drive channel while exchanging setpoints and diagnostics over PROFIBUS-DP. Both analog and digital feedback loops are supported through its integrated I/O, eliminating the need for separate terminal blocks. The first encoder socket accepts signals compatible with IndraDyn, HIPERFACE, and 1 Vpp feedback systems, allowing high-resolution position tracking, whereas a second port can read HSF or resolver formats for legacy motors. Parameter access and service tasks are possible through the front-mounted RS-232 serial interface. Internally, the option-3 slot activates cross-communication so that this card can pass process variables to neighboring drives without routing them through the PLC, minimizing fieldbus traffic during coordinated motion.

Safety-related stop energy is handled by the hardware-based Safe Torque Off circuit. The acknowledgment relay provides a control signal rated at DC 24 V / 1 A after the axis reaches a no-torque state, while the logic inputs draw only 3 mA from a DC 24 V supply to confirm the safe command. For fast peer updates, the cross-communication channel operates as master under the IEEE 802.3 standard, forwarding position data through shielded Ethernet jumpers. The supervisory safety chain terminates on a 9-pin female D-Sub connector that simplifies wiring to external gate switches, light curtains, or emergency stop buttons.
