Product Description:
The CSH02.1B-ET-EC-NN-NN-DA-NN-FW is a motion-logic controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Designed to sit inside a drive rack, it coordinates axis commands, feedback, and fieldbus data so servo inverters can follow deterministic references during automated manufacturing. By combining program execution with high-speed communication, the unit acts as the supervisory layer between PLC sequences and the power electronics that energize motors and actuators across packaging lines, machine tools, and material-handling stations.
Electrical service begins with a control supply of DC 24 V, from which the board draws a nominal base load of 17 W. A dedicated inrush limiter restricts the charging period to 1 ms, and the peak current during that event does not exceed <5 A, reducing stress on cabinet fuses. After energization, the processor and I/O sections share a common multi-Ethernet backplane that supports PROFINET, EtherNet/IP, and SERCOS over a single port. The ET communication daughterboard contributes 2.7 W, while the EC encoder interface adds 1.1 W. Conversion to the analog domain is handled by a digital-to-analog path with a throughput of 250 µs, enabling tight velocity loops on fast axes.
Feedback peripherals connect through the multi-encoder socket, and the controller allocates an overall budget of 6 W for sensor power. It can source 12 V or 5 V rails, each capable of 500 mA, and a separate digital output channel also delivers 500 mA to external relays or LEDs. High-resolution command values are preserved throughout the signal chain: the analog monitor output is quantized at 24 mV/incr, the D/A current path resolves to 12 bit, and the D/A voltage path reaches 14 bit. For absolute encoders running over the EC module, the internal logic requires only 1.1 W, leaving reserve power for application-specific extensions.
