Product Description:

The CSH01.1C-SE-EN1-MEM-MD1-S1-S-NN-FW is a motion-logic controller module manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It installs in IndraDrive systems and coordinates servo axes, providing position control, safety monitoring, and encoder emulation in a compact rack format. By hosting the control logic and I/O resources for axis cards, the unit links drive hardware with higher-level PLCs and HMIs for deterministic data exchange in multi-axis automation tasks such as packaging, material handling, and assembly. Its motion-logic role keeps the axis controller and drive electronics closely coupled during starts, stops, and synchronized moves.

The controller communicates with drives and PLCs through the real-time fieldbus SERCOS II, which provides synchronous cyclic data transfer for velocity and position loops. Local process feedback is accepted on a single channel with 1 analog input, while machine commands or reference values can be sent through 2 analog outputs. When additional discrete signaling is required, the board offers 12 x 24 V digital expansion inputs for sensor states and 8 x 24 V digital expansion outputs for contactors or indicator lamps. These channels are galvanically isolated from logic power and are scanned during each communication cycle so external events can be incorporated into the motion sequence with consistent timing. This mix of analog and digital interfaces allows the module to handle motion control and machine-level signaling within the same control layer.

The emulation section reproduces incremental or absolute encoder signals over cables up to 40 m long, and the square-wave pair can be generated at frequencies up to 1 MHz. Resolver feedback from connected MHD or MKD motors is energized at 18.2 Vpp and evaluated at a carrier frequency of 4 kHz, which supports precise rotor angle calculation during highly dynamic motion. Integrated safety I/O uses a D-Sub 9 connector to process 24 V inputs and outputs for machine stop and acknowledgment functions without external relays. This arrangement lets the controller exchange motion, feedback, and safety-related signals from one module location inside the IndraDrive platform.
