Product Description:

The CSH02.1B-CC-EC-CN-NN-EC-NN-FW is a motion-logic controller from Bosch Rexroth Indramat in the CSH Advanced Controllers series. The device coordinates drive axes, handles fieldbus communication, and closes motion loops for servo systems used in industrial automation cells. By combining communication management, encoder handling, and local digital I/O in one module, it links higher-level PLCs with drive amplifiers and sensors while keeping control tasks centralized. This layout reduces the need for separate interface hardware and helps keep machine wiring more organized.

Primary axis-control traffic is exchanged over a Sercos III master interface, allowing deterministic telegrams to and from connected drives. Current commands are refreshed every 62.5 µs, and the short update interval helps the controller respond quickly to changing load conditions during synchronized motion. Local I/O resources include 11 digital inputs, five configurable digital outputs, and two probe inputs for edge-aligned capture tasks. The module also provides two ±10 V analog outputs for direct actuator or reference-signal generation without extra converters. For service access, it includes an Ethernet port compliant with 100Base-TX, which supports straightforward connection to setup and diagnostic tools.

The integrated CANopen fieldbus can manage up to 127 nodes, allowing the controller to serve distributed devices across a larger machine network. Position feedback is processed every 250 µs, which supports stable closed-loop behavior when encoder data must be evaluated at regular intervals. Three rear expansion slots allow extra encoder or I/O cards to be added when a machine requires more local connectivity. Each of the two encoder interfaces can supply either 5 V or 12 V, with a current capacity of 500 mA on each rail for external feedback devices. The controller has no integrated safety option, so safety-related stopping or muting must be handled by external devices.
