Product Description:

The CSH01.1C-ET-ENS-NNN-MD2-S2-S-NN-FW controller is produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Mounted inside IndraDrive power sections, this plug-in board executes axis control, fieldbus routing, and safety supervision for servo applications. It forms the processing core that interprets encoder feedback, scales analog process signals, and directs digital outputs. This arrangement allows connected axes and machine functions to be coordinated from a compact control platform inside the drive system.

This controller accepts a DC 24 V supply. The two differential analog channels present an input impedance of 160 kOhm (typical) and accommodate a programmable measurement span of ±10 V. There are 11 digital inputs, and each channel is rated for 24 V at 3 mA with hardware debouncing. Transistor outputs share a rating of 24 V / 0.5 A and can drive field devices directly. A relay contact rated for DC 24 V at 1 A provides galvanically isolated switching for auxiliary circuits. Two probe inputs accept pulses as short as 4 µs for edge capture in high-speed processes. The ENS encoder interface passes absolute position data to the motion kernel, and option slot 3 adds additional digital I/O together with an SSI encoder link for synchronized serial feedback.

During power-up, the module experiences an inrush current of 4 A, after which its steady demand stabilizes at 7.5 W. Motion functions are secured by the Safe Motion suite, which supervises velocity limits and safely disables torque without external circuitry. System networking is handled by the Multi-Ethernet interface, so the same hardware can operate on PROFINET, EtherNet/IP, EtherCAT, or Sercos installations. This helps the controller fit different network standards while keeping signal handling and motion control in one drive-mounted unit.
