Product Description:

The CSH02.1B-CC-EC-EC-L3-EM-NN-FW controller card is produced by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. It plugs into IndraDrive power sections to supervise axis motion, safety, and network timing in industrial automation equipment. By combining PLC logic with real-time encoder processing, the card coordinates torque, speed, and position loops across multiple drives, making it the central command element for packaging lines, machine tools, and material-handling cells where deterministic synchronization is required.

At idle, the module draws a base load of 17 W, which is useful when sizing control cabinet power and ventilation. Motion commands and diagnostics travel over the SERCOS III master interface, which maintains fixed cycle times for synchronized axes. Feedback accuracy is supported by an 11-bit resolution on current inputs and a 13-bit resolution on voltage inputs, while outgoing setpoints leave the DAC in steps of 24 mV per increment. One encoder-emulation port reproduces incremental signals for legacy hardware, while two separate evaluation channels accept absolute or incremental encoders, allowing mixed-sensor architectures without additional interface cards.

The board powers external sensors through 5 V and 12 V rails rated at 500 mA each, eliminating separate field supplies. Shielded encoder and motor leads may extend up to 40 m, with signal integrity supported by a distributed capacitance of 60 pF/m, while unshielded runs are limited to 30 m. Resolver feedback is driven by an 8 kHz carrier delivered at 60 mA peak and 40 mA rms, enabling precise angle decoding during rapid acceleration. All motion outputs can be silenced instantly through the STO (Safe Torque Off) channel, which supports functional safety without external contactors.
