Product Description:

The CSB02.1B-ET-EC-PB-S5-EC-NN-AW is a modular drive controller manufactured by Bosch Rexroth Indramat for the CSB Drive Controllers series. In industrial automation, it supervises servo torque, position, and velocity while passing real-time status data to higher-level PLCs, unifying motion execution with plant sequencing. Integrated encoder supplies, fieldbus ports, and safety logic are combined in a single housing so cabinet space is conserved and wiring paths are shortened. This layout helps the controller fit packaging, material-handling, and assembly machines where coordinated motion and compact panel design are both important.

The controller’s standby logic draws 17 W of base power, keeping parameter memory and diagnostics active without engaging the main power stage. Two differential analog inputs accept command signals across a ±10 V range, and the input is processed at 13-bit resolution for fine setpoint scaling. For actuator feedback or process reference, the device provides 2 analog outputs. Motion and sequence events are triggered through 11 digital inputs, and an extra bank of 5 configurable I/O lines can be assigned as needed. Encoder supply rails deliver power for incremental or absolute transducers, and two dedicated S5 encoder evaluation channels handle position data without external breakout boards. This arrangement allows signal acquisition, command handling, and feedback processing to remain inside the controller rather than relying on separate interface hardware.

Multi-Ethernet communication is presented through an RJ-45, 8-pin jack that supports the IEEE 802.3u 100Base-TX standard, allowing deterministic exchange of control frames with motion coordinators. Three optional card slots, totaling 3, accommodate additional feedback, I/O, or trending modules, while legacy cells can still be integrated through the Profibus D-Sub, 9-pin female connector. Safe Motion functions are executed under the certified Safe Motion (S5) technology package, enabling safety-related stop, limited speed, or position monitoring without separate relay logic. The combination of Ethernet networking, optional expansion capacity, and integrated safety functions makes the unit suitable for control architectures that mix newer communication methods with installed fieldbus equipment.
