Product Description:
The CSH02.1B-CC-EC-NN-S4-DA-NN-FW is an advanced motion-control card engineered by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive rack, it supervises multi-axis positioning, exchanges real-time data with drives, and routes encoder signals to the system CPU. By combining network communication, local I/O, and certified safety logic on one board, the product reduces the need for separate interface modules in the cabinet. This arrangement helps keep signal handling centralized while supporting coordinated motion in industrial automation cells.
At the fieldbus layer, the controller functions as a SERCOS III master, allowing synchronized telegram updates to every axis. Incoming current feedback is digitized with 12-bit granularity, while the internal digital-to-analog converter refreshes command outputs every 250 µs. Each incremental step represents 24 mV per increment, allowing fine voltage modulation for torque-mode drives. Separate voltage channels are sampled with a 14-bit resolution to monitor supply quality in parallel, and a multi-encoder interface supports EnDat, SSI, and incremental feedback formats for flexible machine integration.
The EC option draws 1.1 W, and its 12 V rail can source 500 mA while the parallel 5 V rail supplies the same current for auxiliary electronics. Analog conditioning holds linearity up to 400 kHz for sine inputs, while square-wave signals are accepted to 1000 kHz for fast edge detection. When the S4 module is fitted, resolver feedback is not supported, yet Safe Motion functions remain active because the option delivers 350 mA and dissipates 2.5 W. Dual digital and analog I/O expansion is also available, allowing additional sensors and actuator lines to be connected without placing that traffic on the main fieldbus cycle.
