Product Description:

The CSH01.1C-S3-ENS-EN2-MD1-S1-S-NN-FW is a single-axis motion and safety controller produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It operates as the central command board in industrial drive assemblies. It coordinates motor feedback, high-speed network traffic, and localized input and output so automated cells can synchronize axes and verify critical process signals.

Base power draw is 7.5 W, keeping cabinet thermal budgets low during standby. The controller exchanges cyclic data over SERCOS III and supplies a dedicated RJ-45, 8-pin connector for that deterministic Ethernet ring; an auxiliary RS-232 maintenance link can be run up to 15 m without signal boosters. Position and speed feedback are accepted through IndraDyn / Hiperface on encoder interface 1 and EnDat 2.1, 1 Vpp, or 5 V TTL on encoder interface 2. High-resolution analog commands leave the board at 19.5 mV/inc, while the Option 3 slot is populated with a digital I/O extension that adds further field contacts. Because the motion logic shares the same platform as Rexroth IndraDrive inverters, parameter sets can be copied across axes for quicker setup.

Inside the En2 encoder supply circuit, the board delivers DC 5.0 V at up to 350 mA, provided the external transducer maintains a termination of 35 Ω. The MD1 daughter card carries 12 digital inputs and eight transistor outputs for direct sensor and valve wiring, while the Safety Technology I/O module routes separate 24 V chains rated 3 mA on input and 0.5 A on output to satisfy controlled-stop categories. All safety terminals are galvanically isolated from the standard I/O domain, preventing fault propagation between emergency circuits and general automation lines. The digital I/O extension can expand these counts without altering fieldbus mapping.
