Product Description:

The Bosch Rexroth Indramat CSH02.1B-CC-EC-ET-NN-DA-NN-FW belongs to the CSH Advanced Controllers series. This unit is a motion-logic controller that supervises servo drives, acquires feedback from several encoder formats, and exchanges data with higher-level PLCs. By combining trajectory generation, I/O processing, and network routing inside one module, it shortens cabinet wiring and supports synchronized operation of packaging, printing, and material-handling equipment. It installs on a DIN rail beside IndraDrive power sections and supplies regulated encoder power for compact automation cells. This arrangement lets one controller coordinate axis movement and peripheral signals from a single location.

The controller draws a base load of 17 W, a figure useful when sizing control-cabinet supplies and UPS buffers. Two differential analog outputs are refreshed every 250 µs, allowing smooth velocity or pressure commands. Each channel is generated with a 14-bit resolution, so signal steps remain well below one percent of full scale. The internal encoder regulator can deliver up to 500 mA at 12 V for closed-loop sensors and mirrors the same current on its 5 V rail for TTL feedback devices. The DA option card provides 2 analog inputs so external transducers, such as load cells or temperature probes, can be read directly without an extra interface. This allows the controller to issue command signals and read process values without separate analog hardware.

The DA board also handles six digital inputs and 6 digital outputs, plus two configurable lines that can act as triggers or status flags. Total encoder power available to all feedback channels is limited to 6 W, keeping heat rise predictable inside sealed enclosures. The multi-encoder module adds 1.1 W to the load, while the multi-Ethernet interface contributes another 2.7 W. Cross-communication between multiple controllers is coordinated by the integrated SERCOS III master, providing deterministic data exchange across drive chains. Those additional loads help account for cabinet heat buildup when communication and feedback functions are active at the same time. Because the unit includes no built-in safety technology, emergency-stop and guard-locking devices must be handled with external safety relays.
