Product Description:

The CSH02.5B-CC-EC-NN-L3-NN-NN-NW controller is produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It operates as the central motion processor for multi-axis drive packages, executing position, velocity, and torque loops while distributing synchronized setpoints to decentralized I/O. By combining computation, real-time fieldbus handling, and safety logic in one module, the unit serves as the command source in automated assembly, packaging, and machining cells where coordinated movement and deterministic timing are required. This role allows the controller to manage axis behavior and machine responses from a single control point instead of relying on separate motion hardware for each function.

Process signals enter through 11 digital inputs, while control voltages and actuator references exit through 2 analog outputs. These channels support direct connection to limit switches and to proportional devices or inverters that use voltage-based command signals. Networked motion is handled by the integrated SERCOS III master, which sends deterministic telegrams to connected drives on every cycle. For personnel protection, the controller provides STO (Safe Torque Off), which disables drive torque without removing feedback power. Rapid edge capture is supported because the square-wave feedback port accepts frequencies up to 1000 kHz, allowing high-resolution incremental encoders to be used without signal loss during fast motion.

Axis feedback flexibility is provided by the multi-encoder interface, and the unit can supply up to 6 W of encoder power shared between 5 V and 12 V rails, each limited to 500 mA. Two probe inputs are available for touch-trigger measurement tasks, and three unipolar analog inputs support signals such as temperature or load-cell monitoring. System-specific extensions can be installed in 3 optional slots while the enclosure maintains a depth of 103 mm, along with a thickness of 49.5 mm and a height of 241 mm. Five configurable discrete outputs are also included for status signaling and coordinated machine responses during operation.
