Product Description:

The CSH01.1C-ET-EN1-NNN-MEM-NN-S-NN-FW belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. This single-axis motion control section is designed to plug into IndraDrive platforms and handle position, velocity, and diagnostic tasks in industrial automation cells. Its role is to interpret feedback from a variety of encoder types, process commands from higher-level PLCs or networks, and generate drive-ready signals that keep the connected motor synchronized with the programmed profile.

An analog-to-digital converter with a resolution of 12 bit supports precise parameter sampling, while the communication slot accepts Multi-Ethernet protocols so the module can join mixed plant networks without daughterboards. Electrical signaling follows the 100Base-TX Ethernet standard for 100 Mbit/s data rates over twisted-pair cable. The EN1 reference channel is supplied internally at 8 V, giving sensors a regulated source independent of the main logic rail. Position feedback can enter through the resolver or HSF interface; its resolver carrier is fixed at 4 kHz, and the card can emulate both absolute and incremental formats to match legacy drives. One axis is managed per controller, and real-time status appears on the integrated single-line display.

The memory-mapped encoder port streams data with a maximum rate of 1 MHz, making it suitable for high-speed linear scales. Network wiring can extend up to 100 m on the ET port before a switch is required, while the MEM channel supports 40 m. Resolver excitation is generated at 18.2 Vpp so the sine and cosine coils receive a stable signal, and the HSF path supports 1.0 V amplitude with 10 kΩ input resistance. Setup or service laptops can connect through the built-in RS232 serial interface for parameter upload and trace capture.
