Product Description:
The CSH01.1C-ET-ENS-EN2-MA1-S2-S-NN-FW controller is manufactured by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. This device serves as the central processing and interface module for IndraDrive units, combining axis control, fieldbus communication, and safety supervision in a single card. Within an automation cabinet, it links drives, I/O, encoders, and higher-level PLCs so synchronized motion profiles and protection functions can be executed without separate gateway hardware. It is intended for coordinated servo applications that require motion control and communication within the same drive platform.
The controller contains two base analog outputs rated at 2 × 5 V / 1 mA, enabling low-power command signals for external drives. Its internal logic and sensor blocks are energized by a digital I/O rail that can source 1.1 A, so a moderate number of proximity switches and photoelectric sensors can be powered directly from the unit. Network traffic is handled by the Multi-Ethernet module, and the copper port complies with 100Base-TX for deterministic real-time data exchange. The MA1 option board adds two differential analog inputs and two voltage outputs. The analog channels operate over ±10 V, and the conversion depth is 12-bit, giving adequate resolution for closed-loop pressure or dancer feedback.
Axis feedback is linked through the EN2 connector, which provides a 5.0 V DC supply with a continuous delivery of 350 mA for the second encoder. The ENS connector supplies 12 V for IndraDyn S, HIPERFACE, or EnDat 2.1 transducers, and the interface also accepts EnDat 2.1, 1 Vpp, or 5 V TTL signals. Safety-relevant wiring terminates on a 9-pin female D-Sub plug, and the integrated Safe Motion technology enables STO, SS1, and related functions without additional safety relays. This layout allows secondary feedback connections and safety circuits to be handled directly at the controller.
