Product Description:

The CSH02.1B-ET-EC-EM-SB-NN-NN-FW is an automation controller produced by Bosch Rexroth Indramat and supplied within the CSH Advanced Controllers series. It serves as the central motion and I/O coordinator in multi-axis drive systems, linking servo inverters with higher-level PLCs through deterministic Ethernet networks. By integrating fieldbus communication, encoder processing, and local input channels on one card, the unit streamlines cabinet wiring and supports fast response in packaging, printing, and material-handling machines. Its role is to keep command exchange, feedback handling, and local signal processing on a single platform instead of spreading those functions across separate modules.

This controller draws only 17 W on its basic board, leaving cabinet power available for peripheral devices. A Multi-Ethernet port handles real-time traffic without additional gateway hardware, and the controller provides 11 digital inputs for limit switches, sensor flags, or interlocks. The unit also provides 2 analog outputs with isolation for retransmitting torque, speed, or process variables to external monitors. Five discrete digital I/O points supplement the dedicated inputs for onboard handshaking and local status exchange. The card accepts up to 3 optional slots, allowing the addition of extra encoder channels, safety modules, or specialty bus couplers. Resolver feedback is not supported, so motion capture relies on the multi-encoder interface instead.

For network flexibility, the ET section supports SERCOS III, EtherCAT, EtherNet/IP, and PROFINET IO while conforming electrically to IEEE 802.3. The EC A/D converter samples incoming encoder data at 12-bit resolution, which supports accurate processing of connected feedback signals. An EM channel provides encoder emulation and an SSI stream for legacy drives, and the interface supports sine inputs up to 400 kHz and square-wave inputs up to 1000 kHz. Motion shutdown and restart sequences are handled through the controller’s integrated Safe Motion Bus, which keeps safety-related communication on the same controller platform without separate point-to-point wiring.
