Product Description:

The CSH02.5B-CC-EC-ET-L3-EC-NN-FW is an automation controller manufactured by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed next to Rexroth inverter modules, it coordinates motion sequences, supervises current loops, and exchanges process data with higher-level PLCs. The controller converts application commands into synchronized axis signals, allowing assembly cells, conveyors, and packaging machines to run repeatable cycles without an external PC.

This model communicates with drives through the Sercos III Master interface, so timing between devices stays phase-aligned. For torque regulation, it refreshes the current loop every 62.5 µs, while the position loop closes at 250 µs; these fast cycles let the machine react quickly to load changes. The controller has 11 digital inputs for limit switches and sensor flags, and three analog inputs accept velocity or tension references. Two analog outputs provide status signals to external indicators, and the multi-encoder interface supports incremental, absolute, or Hiperface feedback without extra modules. A pair of probe inputs captures real-time positional latches, and three optional slots accept safety or fieldbus hardware for different machine layouts.

On the network side, the integrated Multi-Ethernet port gives access to EtherNet/IP, PROFINET, or EtherCAT without changing hardware. Up to 500 mA of encoder supply current is available for powering incremental or absolute sensors. For high-speed analog acquisition, the voltage input channel offers a bandwidth of 1.3 kHz with a resolution of 14-bit, enabling accurate tension or pressure feedback. The Safe Motion stage implements Safe Torque Off so motors can be rapidly de-energized during an emergency stop. Two probe inputs, relay contacts rated at 30 V and 1000 mA, and dual analog outputs let the controller drive brakes, lamps, or valves directly, reducing auxiliary I/O requirements.
