Product Description:

The CSH01.1C-S3-ENS-NNN-MEM-S1-S-NN-FW is a single-axis control section from the CSH Advanced Controllers series developed by Bosch Rexroth Indramat. Installed inside IndraDrive power units, this module processes motion commands, feedback, and safety signals, forming the logic layer between fieldbus networks and the connected servo mechanics. This arrangement lets the control section exchange real-time data with the power stage while keeping command processing inside the drive platform. It is designed to coordinate high-resolution encoders, manage safe I/O, and relay data to higher-level PLCs, making it a core component in industrial automation lines that need precise position and velocity control.

Five differential analog channels accept a signal range of ±10 V, and each channel presents 160 kΩ of input resistance to minimize loading on external sensors. The controller starts with a base internal demand of 7.5 W, allowing compact cabinet thermal designs. Motion and parameter data reach the board through the real-time fieldbus SERCOS III, and two RJ-45 8-pin ports enable ring or line topologies. During power-up, the circuitry draws a maximum of 4 A of inrush current, so upstream supplies must accommodate this brief surge. Feedback arrives on a D-Sub 15 female connector that supports IndraDyn, HIPERFACE, and 1 Vpp formats, while the input termination of 120 ohms and an encoder supply of 11.6 V help maintain signal integrity. Absolute and incremental emulation is available for downstream drives, and a memory interface permits cable lengths up to 40 m.

Position data recorded from the encoder can be rerouted to auxiliary devices through the onboard emulation output, which supports frequencies up to 1 MHz. For time-critical interlocks, the controller reports fault status with a maximum pulse width of 100 ms. Integrated safe torque off channels accept control signals rated at 24 V / 3 mA and drive external relays with an output capability of 24 V / 0.5 A, enabling compliance with machine safety circuits without separate interface modules.
