Product Description:

The CSB02.1B-ET-EC-CN-NN-NN-NN-AW is a compact drive controller from Bosch Rexroth Indramat in the CSB Drive Controllers series. As a central node, it conditions feedback, manages fieldbus traffic, and issues torque or velocity commands to the connected power section of a servo axis during closed-loop motion. Within an automated cell, the unit merges sensor information with motion profiles so that conveyors, pick-and-place arms, or machine tools can run deterministic cycles, maintain repeatable positioning, and respond quickly to command changes.

The controller has 2 analog outputs, and each output uses a step size of 24 mV/Incr. Three buffered analog input channels accommodate process signals such as tension or pressure, and digital signaling capacity includes 11 digital inputs plus five configurable digital I/O points for edge-triggered events and status exchange with nearby devices. The EC analog-to-digital converter uses 12 Bit resolution, and the encoder interface can process square-wave feedback up to 1000 kHz. The primary network side supports Multi-Ethernet protocols, so a single board may switch between EtherNet/IP, PROFINET, or SERCOS III. Local motion buses rely on a D-Sub 9-pin connector for the CANopen secondary interface, allowing daisy-chain cabling to smart actuators or remote I/O blocks on the same machine.

High-speed host communication passes through an ET link that conforms to 100Base-TX. The encoder supply rail can deliver 500 mA to power sine-cosine or incremental transducers without an external source, which helps simplify wiring around the feedback device and keeps the transducer supply local to the controller. The unit provides 3 optional slots for safety or encoder expansion cards, allowing the controller to be configured for different feedback or safety requirements. For precise trigger capture, the front panel includes 2 probe inputs that latch position counters on fast signal edges during synchronized motion and event-based measurements.
