Product Description:

The CSH01.1C-SE-ENS-EN1-EN2-S2-S-NN-FW is a control section from Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in IndraDrive systems, this module provides closed-loop command processing for a single servo axis in machine tools, material-handling frames, and packaging lines. It acts as the intelligence layer between the power section and connected field devices, converting higher-level PLC commands into precise motion profiles while supervising safety functions and local I/O. This arrangement lets the power section handle current delivery while the control section manages motion logic and interface signals.

Its analog front end presents an input resistance of 160 kOhm, limiting loading on external transducers and permitting accurate voltage sensing over long cable runs. The analog outputs are generated in steps of 19.5 mV/inc, and the converter uses 8-bit resolution that suits coarse actuator references such as hydraulic valves. The axis option is single-axis, so processing resources are dedicated to one drive channel instead of being shared across multiple axes. Real-time setpoint and feedback data travel over the optical SERCOS II interface, which carries cyclic telegrams synchronized to the controller clock for deterministic motion control and predictable data exchange.

Digital signals are handled through high-side drivers that can source up to 0.5 A on each output, while the combined load for all outputs is limited to 1000 mA to protect board traces. Position sensors that require line power receive a stabilized 5 V supply on the EnDat or TTL connector, while resolvers are energized separately at 8 V to reduce cross-talk between feedback circuits. Functional safety is integrated through Safe Motion, allowing certified stop and monitor modes without external relays. The section draws a maximum of 1.1 A from the I/O bus, and parameters are stored on a removable MMC for local retention.
