Product Description:

The CSH01.1C-ET-ENS-ENS-MD1-NN-S-NN-FW is a single-axis control section in the CSH Advanced Controllers series from Bosch Rexroth Indramat. It attaches to IndraDrive power sections to execute position, velocity, and torque loops for electric servos in automated machinery. By housing motion logic, communication interfaces, and local I/O on one board, the unit coordinates actuators and sensors so that production lines, packaging cells, or material-handling axes respond precisely to the higher-level PLC.

The control section draws a steady 7.5 W of internal power and is supplied from an external 24 V DC logic rail, so the auxiliary supply can be sized with minimal headroom. Two encoder channels accept IndraDyn, Hiperface, 1 Vss, or TTL signals and feed them with a regulated 12 V reference to close feedback loops without separate conditioners. For network traffic, the board presents an RJ-45, 8-pin jack that follows the 100Base-TX Ethernet physical layer, and the same port can switch among Sercos III, EtherNet/IP, or PROFINET as master protocols. Two additional fieldbus sockets let the drive segment information toward decentralized peripherals, while the RS232 serial interface remains available for diagnostics and setup.

Machine-side signals land on spring-cage terminals where the controller offers 12 digital inputs for status bits and 8 digital outputs for actuator commands. Pulse lengths down to 100 ms can be generated without software polling when tight timing is needed. The startup peak is limited to 4 A of inrush, protecting control fuses during power-up. Two analog output channels transmit speed or torque references to legacy drives, and a relay contact rated at 24 V DC, 1 A provides a hardwired fault or enable path. When higher channel density is required, the Option 3 slot accepts a Digital I/O Extension so additional sensors or interlocks can be bridged into the same motion node.
