Product Description:
The CSB02.1A-ET-EC-NN-L3-NN-NN-FW drive controller belongs to the CSB Drive Controllers series produced by Bosch Rexroth Indramat. Installed inside the control cabinet, it links the machine PLC to servo amplifiers and feedback devices while handling trajectory processing, fieldbus traffic, and functional safety for automated production cells. By integrating communication, local I/O scanning, and encoder evaluation in one module, the device shortens wiring runs and simplifies setup of multi-axis systems. This arrangement also keeps motion control and signal handling within the same platform, which helps maintain coordinated machine operation.
Its single analog input accepts a bipolar range of ±10 V, and the value is digitized with 14-bit granularity for high-resolution process signals such as force or tension references. The controller has 7 digital inputs, allowing it to react to limit switches, sensors, or program flags during machine operation. Network traffic moves through the Multi-Ethernet interface, and two ports arranged in line topology terminate on an 8-pin RJ-45 connector that follows the 100Base-TX standard for 100 Mb/s data exchange with PLCs or higher-level IPCs. A multi-encoder interface supports EnDat, SSI, and incremental formats so position data from each axis reaches the motion kernel without separate interface cards.
The module draws only 17 W from its DC 24 V control supply, which helps limit heat buildup inside densely populated cabinets. Its integrated safety channel implements Safe Torque Off; when activated, it removes gate signals from the power stage and can source up to 350 mA on the STO output to feed external relays. Two probe inputs with a minimum pulse width of 4 µs capture encoder marker positions during high-speed processes such as press stamping. The multi-encoder port can source up to 500 mA to power resolvers or optical feedback heads, while the second probe input and the remaining digital lines support time-aligned latching of product or tool positions during fast machine cycles.
