Product Description:

The CSH02.1B-CC-EC-PB-NN-DA-NN-FW is a motion and logic controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. The unit coordinates a single servo axis and communicates with drive power sections from the HCS02, HCS03, HCS04, HMS01, and HMS02 families. Used in industrial automation, it generates command profiles, handles encoder feedback, and passes synchronized data to downstream drives so that positioning, speed, and torque loops are closed with consistent timing on factory floors.

The controller’s analog front end accepts differential voltage or current signals. Its input bandwidth of 1.3 kHz lets fast sensors be sampled with low phase error in high-response loops. Resolution is 14 bit, so each conversion divides the full scale into 16,384 discrete steps and enables fine setpoint granularity. Analog outputs leave the module in steps of 24 mV/incr, so the drive receives small voltage changes during torque or speed reference updates. Coordination with connected inverters is carried out through a deterministic SERCOS III master interface, allowing cyclic telegram times in the sub-millisecond range. Because the device is designed for single-axis control, processing resources are focused on one motor and cross-channel latency is avoided.

The remaining electrical services are straightforward. Logic circuitry is powered from a DC 24 V control supply, isolating the controller from high-energy drive buses and allowing motion memory to be retained during mains shutdowns. Field-level communication with PLCs or cell controllers is provided by PROFIBUS, routed through a D-Sub nine-pin female connector that follows DIN EN 50170 wiring conventions. Internal consumption stays at 17 W, so the unit can be mounted beside temperature-sensitive electronics without forced ventilation. An optional digital and analog I/O extension board can be attached when sensor counts grow, and a multi-encoder interface supports resolver, incremental, and absolute feedback formats without extra gateways.
