Product Description:

The CSH02.1B-CC-EC-NN-S5-DA-NN-FW motion and safety controller is produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. The unit coordinates multiple drive axes, process sensors, and machine-level safety through its built-in Sercos III master interface, while the physical network follows the IEEE 802.3 Ethernet standard. Inside an automation cell, it serves as the central command layer, issuing deterministic setpoints, collecting high-speed feedback, and managing safety zones for packaging, handling, or machining lines. This arrangement reduces the need for separate coordination hardware in multi-axis systems.

The analog section delivers an output granularity of 24 mV/incr, and each channel updates within 250 µs, providing tight control of proportional valves or torque references. Incoming 4–20 mA loops encounter a 300 ohm input path and are digitized with 12-bit resolution, while voltage inputs are sampled at 14-bit depth. The latter channel maintains a flat response up to 1.3 kHz, so high-frequency vibration data can be captured without aliasing. Two independent encoder evaluation circuits handle incremental or absolute feedback and can source 500 mA to external transducers. An EC expansion draws only 1.1 W, and the S5 safety option adds 2.5 W, allowing fanless cabinet operation even in compact enclosures.

The integrated safe motion block sources 350 mA on each safety output and can dissipate 400 mJ during rapid shutdown, helping protect field devices from contact damage. One controller can supervise a protective perimeter up to 2500 m long and manage 35 distributed safe I/O nodes, which supports large conveyor systems without additional relays. Safety handling, drive communication, and encoder processing are therefore combined within the same control platform, which simplifies system layout and keeps response handling centralized.
