Product Description:

The CSH02.1B-CC-EC-NN-NN-DA-NN-FW is an axis controller module from Bosch Rexroth Indramat in the CSH Advanced Controllers series. Installed inside multi-axis drive cabinets, it manages torque, velocity, and position loops for servo drives used in packaging machinery, material-handling cells, and precision machine tools. Acting as the central processing element between feedback devices and the fieldbus network, it supplies deterministic motion commands while allowing the supervisory PLC to handle higher-level logic. This arrangement supports centralized coordination of multiple axes without requiring a separate motion processor at each drive.

Real-time behavior is set by several internal cycles. The current loop closes every 62.5 µs, while the velocity loop completes in 125 µs. Both feed a position loop that refreshes every 250 µs to limit following error at high feed rates, and analog command channels are converted with a granularity of 24 mV/incr. Motor-feedback currents are digitized to 12 bit, and the encoder interface accepts multiple signal formats so sensor data can be translated directly into synchronized drive commands without external gateways. Because safety technology is not included, any STO or SS1 functions must be provided by external hardware.

Field communication relies on a Sercos III master port that distributes cycle-synchronous setpoints to connected drives. Local feedback arrives through the multi-encoder interface, and machine signals can be expanded by a digital/analog I/O extension. Two configurable lines on connector X37 supplement six fixed inputs and six fixed outputs, while connector X38 adds two further inputs and two outputs for auxiliary devices. Voltage measurements are digitized with a resolution of 14 bit, permitting fine scaling of process variables for connected sensors and analog signals.
