Product Description:

The CSH01.1C-ET-ENS-ENS-NNN-L2-S-NN-FW is a control section module produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed on an IndraDrive power section, it coordinates motion commands, network traffic, and encoder feedback for servo axes in automated machinery. The unit acts as the programmable intelligence between field networks and the drive electronics, providing diagnostic data, safety channels, and configuration storage that simplify system integration on factory floors.

The module communicates through Multi-Ethernet, enabling PROFINET, EtherNet/IP, or EtherCAT to be selected in software without extra hardware. Network cables terminate at the two RJ-45 sockets labeled X24 and X25, which support line-topology wiring inside a control cabinet. Traffic conforms to the IEEE 802.3u Fast Ethernet standard, providing deterministic exchanges required by modern motion buses. The copper interface uses a 100Base-TX physical layer that delivers 100 Mbit/s over standard twisted-pair cabling. For analog signaling, the board offers a single output limited to 5 V at 1 mA, allowing low-power reference values or diagnostic voltages to be sent directly to external measurement equipment.

The internal I/O rail can source up to 1.1 A so proximity switches and photo-eyes receive power without an auxiliary supply. A form-C relay channel rated for DC 24 V at 1 A provides galvanically isolated status or interlock contacts. Drive safety is handled through Safe Torque Off; the nine-pin D-Sub STO connector feeds this signal to the power stage for immediate motor de-energization during emergencies. Service access is available through the embedded RS232 interface, while a MultiMediaCard slot stores parameter sets. Standard encoder evaluation on two inputs recognizes HIPERFACE, EnDat 2.1, and 1 Vpp formats, and the third option slot remains unused so OEMs can reserve space for future extensions.
