Product Description:

The CSB02.1B-ET-EC-EP-NN-EC-NN-FW drive controller is produced by Bosch Rexroth Indramat and belongs to the CSB Drive Controllers series. Designed for multi-axis automation, the unit supplies command processing, local I/O handling, and feedback evaluation for servo inverters on a common power rail. Within a machine cell it functions as the supervisory node that links motion sequences to higher-level PLC or industrial Ethernet networks while coordinating safety interlocks and diagnostic reporting. It is targeted at packaging, printing, and material-handling stations where compact control hardware reduces panel depth.

I/O capacity is sized for moderate machine footprints. Three differential analog channels are sampled at a resolution of 13 bit, allowing temperature, pressure, or position sensors to be read without a separate converter. Motion commands or process variables can be issued through 2 analog outputs, and the controller offers 5 configurable I/O points that can be switched between sourcing or sinking logic as the application demands. Dedicated fast reactions are handled by 11 digital inputs with debounce filtering. Two probe inputs latch encoder position on external events, and the internal encoder supply can deliver up to 6 W, enough for high-resolution optical feedback devices. A relay contact rated at 1000 mA provides field power switching, while an 8 kHz resolver channel is present for analog feedback options.

Real-time communication is selectable among EtherCAT, EtherNet/IP, PROFINET IO, sercos III, all routed through a shielded RJ-45, 8-pin connector that complies with IEEE 802.3u. Frames are exchanged at 100Base-TX speeds over twisted-pair runs up to 100 m without repeaters, enabling cabinet-to-cabinet links. During operation the electronics draw only 17 W, so heat dissipation is low and cabinet ventilation requirements remain minimal.
