Product Description:

The CSH02.1B-ET-EC-EC-S4-DA-NN-FW controller is built by Bosch Rexroth Indramat within the CSH Advanced Controllers series. This unit serves as the central processor in multi-axis drive systems, executing motion profiles, logic sequences, and real-time communication for industrial automation equipment in coordinated motion applications. By combining high-speed control loops with integrated Ethernet connectivity, it directs servo drives, collects feedback, and synchronizes axes so packaging machinery, assembly robots, and web-handling lines maintain precise position and velocity relationships during production and during coordinated start-stop transitions.

Two analog output channels deliver a span of ±10 V, and each increment of the converter is 24 mV/incr, allowing fine-grained reference signals for external amplifiers. The outputs can drive loads down to 2 kΩ without distortion, supporting common drive and sensor interfaces, including reference inputs on drives and process devices. Current regulation is refreshed every 62.5 µs, while field traffic on the SERCOS-compatible bus follows a 250 µs communication cycle. The controller also provides three differential analog inputs, five configurable digital I/O points, and two probe inputs for high-speed edge capture.

The velocity loop closes every 125 µs, supporting rapid response to changing load conditions. Up to 500 mA is available on each digital sourcing output, enabling direct actuation of contactors or hydraulic valves without relays. Machine signals are accepted through 11 dedicated digital inputs, and deterministic network routing is handled by 2 Ethernet ports that support a daisy-chain or redundant ring topology. Two encoder interfaces and three option slots allow resolver feedback, safety I/O, or additional fieldbuses to be added as needed to match machine feedback and communication requirements.
