Product Description:

The CSH02.5B-CC-EC-ET-NN-NN-NN-NW is an advanced motion and logic controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. The unit is intended to coordinate multi-axis drives, manage diverse feedback devices, and link upper-level PLCs in automated machinery. By combining integrated networking with sub-millisecond control loops, it supplies deterministic command of servo amplifiers and supports consistent positioning, speed, and torque regulation on automated factory lines and process equipment. It is suited to applications that need both axis control and centralized logic in one platform.

Its primary fieldbus is the SERCOS III master, while an auxiliary channel supports Multi-Ethernet protocols for simultaneous data exchange with supervisory systems. Electrical wiring to those networks uses 100Base-TX signaling over standard twisted-pair cabling. The controller refreshes its current loop every 62.5 µs, the velocity loop every 125 µs, and the position loop every 250 µs, allowing cascaded control layers to remain synchronized. A 500 mA digital output source drives external indicators or low-power coils, and the built-in relay contact can switch loads up to 30 V. Resolver excitation at 8 kHz maintains stable amplitude for inductive feedback devices. These functions allow the controller to handle communication and real-time motion tasks within the same housing.

The multi-encoder interface accepts EnDat, resolver, and incremental signals, and its encoder supply provides 500 mA with a power allowance of 6 W to support high-resolution feedback heads. EnDat 2.1 cabling can reach 75 m in sense-line layouts without degrading position fidelity. Signal conditioning uses a sine input cutoff of 400 kHz and a square-wave capture bandwidth of 1000 kHz, so the controller can process fine-pitch linear scales at high traverse speeds. Application programming and diagnostics are handled through an Ethernet engineering interface that shares the physical port with the service network, allowing direct access from standard laptops. This arrangement supports both rotary and linear feedback devices used on motion axes.
