Product Description:

The CSB02.1B-ET-EC-EM-L3-NN-NN-FW belongs to the CSB Drive Controllers series from Bosch Rexroth Indramat. As a compact multi-axis drive controller, it coordinates motor torque and position in industrial automation cells, linking servo mechanics to higher-level PLCs and motion planners. Its role is to process feedback, execute motion profiles, and switch power stages so that connected machinery follows commanded trajectories with repeatable accuracy.

For network integration, the unit uses Multi-Ethernet communication, which supports Profinet, EtherNet/IP, or EtherCAT without replacing hardware. The analog monitoring channels provide a 13-bit voltage resolution and an 11-bit current resolution, while each change on the analog output is issued in 24 mV increments to improve closed-loop response. The controller accepts 11 digital inputs at 24 V logic through the front-panel command interface. Direct EtherCAT wiring is provided by the X25 P1 inbound port and a daisy-chain connection to X24 P2, so field devices can be linked without external switches. Conformance to IEEE 802.3u means 100 Mbit half-duplex or full-duplex operation over twisted pair, and the mating connector is an RJ-45 8-pin plug. The extended-scope interface equipment adds encoder emulation, dual-channel analog conversion, and diagnostic LEDs for status indication.

Safety is handled through a hardware-based Safe Torque Off circuit that removes drive energy in less than 10 ms. Position sensors are supported by the multi-encoder interface, which offers SSI absolute emulation, incremental channels, and real-time latching. The controller supplies transducers through a 500 mA 12 V rail and a separate 5 V rail, with the 5 V output also rated at 500 mA for mixed-logic encoders. A Multi-Encoder Interface allows automatic format detection, so emulation can be enabled without jumper changes. These functions let the controller manage feedback devices and safety interlocks within the same control platform.
