Product Description:

The CSH01.1C-S3-ENS-MEM-NNN-S2-S-NN-FW is a single-axis control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. The module plugs into IndraDrive power units and acts as the real-time processing layer that interprets setpoint data, supervises encoder feedback, and issues gate commands to the inverter stage. By performing these tasks, it coordinates precise speed, torque, and position loops for servo axes used in assembly lines, packaging machines, and other automated equipment.

Analog input channels present an impedance of 160 kΩ, so external sensors experience minimal loading and signal distortion. When the application needs an analog reference, the board can source a stable 5 V output that suits typical command potentiometers or positioning transducers. Internal electronics draw only 7.5 W at idle, limiting cabinet heat rise and allowing passive ventilation in many installations. Command data reach the controller over the deterministic SERCOS III network, wired through an RJ-45 8-pin port that supports hot-plug topology. For feedback, a D-Sub 15 female connector supplies the transducer with 12 V and accepts absolute or incremental encoder signals; the controller can also generate matching emulated pulses for legacy drives. A separate RS232 serial interface provides maintenance access up to a 15 m cable length.

Startup stresses remain controlled because the inrush current is limited to 4 A, preventing nuisance trips on tightly rated supply circuits. Time-critical digital commands are accepted with a maximum pulse width of 100 ms, ensuring safety channels react within the specified window. Functional safety is delivered through a D-Sub 9 female connector that routes Safe Motion circuits; its inputs tolerate 24 V / 3 mA signals from light curtains or e-stops, while its solid-state outputs can source up to 24 V / 0.5 A for contactor logic.
