Product Description:
The CSB02.1B-ET-EC-PB-S4-DA-NN-AW is a drive controller from Bosch Rexroth Indramat’s CSB Drive Controllers series. It governs servo or induction axes, supplies encoder power, and exchanges real-time data with higher-level PLCs. In a centralized automation system, it serves as the link between the motion hardware, connected feedback devices, and the plant controller. This combination lets one module handle motion control, safety functions, and fieldbus communication in industrial automation cells.
Its communication section is led by a Multi-Ethernet port set that can run several deterministic Ethernet protocols concurrently. Data moves across a copper medium conforming to 100Base-TX, enabling standard CAT-5e wiring and straightforward integration into existing network layouts. For legacy installations, a secondary channel offers PROFIBUS connectivity, and telegrams travel on the EIA-RS485 physical layer while the internal repeater draws just 75 mA. Safety is addressed through 2 In / 2 Out dedicated safe I/O points that support Safe Motion functions such as STO or SS1 without external safety relays. Additional digital and analog extension terminals, an analog output resolution of 24 mV per increment, and a current input resistance of 300 Ω allow direct connection of sensors or actuators without interface converters.
The analog section is optimized for quick response, and each channel completes a conversion in 250 µs. Voltage inputs are digitized with 14 bit granularity for precise position or pressure feedback, which helps the controller react quickly to changing process signals during closed-loop operation. Encoders can be powered directly, as the drive provides a 6 W budget and up to 500 mA on the 5 V line, preventing dropout of high-resolution feedback devices during rapid moves. A fault relay rated at 30 V is included for brake control or status signaling, removing the need for separate interface hardware. This arrangement allows feedback devices and status circuits to connect directly to the controller.
