Product Description:

The CSH01.1C-SE-ENS-NNN-MD1-L2-S-NN-FW single-axis control section is manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in modular drive stacks, the unit supplies closed-loop position, velocity, and torque commands to a connected power module, allowing coordinated motion in automated machines. By combining analog and digital interfaces with real-time fieldbus links, the product serves as the central logic layer between higher-level PLCs and the motor feedback devices used on the controlled axis.

Signal processing starts with an analog input channel that accepts ±10 V, and the input resistance of 160 kOhm minimizes loading so sensors can drive the port directly. The controller generates an analog command between 0 to 5 V with a maximum source capability of 1 mA, which suits proportional valves or external converters. Four configurable digital I/O points add flexible handshake functions, while seven dedicated inputs capture reference switches and quick-stop contacts. When a higher count is needed, twelve digital extension inputs and eight extension outputs can be wired on the adjacent terminal strip. The single-axis architecture simplifies parameter sets for one servo loop, and the base electronics draw only 7.5 W, helping keep cabinet thermal load low. A standard encoder evaluation interface handles incremental feedback without additional modules.

Real-time motion commands reach the section through the Sercos II fiber-optic ring, and local setup can be performed through an RS232 serial port. The integrated safety channel provides Safe Torque Off, enabling immediate energy isolation to the drive without external relays. During power-up, the board briefly draws 4 A of inrush current, after which normal consumption resumes at the stated base value. For auxiliary actuation, an onboard relay is rated at 24 VDC and 1 A, allowing the controller to switch brakes or contactors within its own circuitry budget.
