Product Description:

The CDB02.1B-ET-EC-EC-NN-S4-S4-NN-NN-AW control unit is produced by Bosch Rexroth Indramat and belongs to the CDB Control Units series. Designed as the core electronics for two servo axes, it houses processing, safety, and feedback resources that synchronize motors with host controllers. The module sits inside a power section of an IndraDrive drive stack where it manages encoder information, converts process variables, and transfers motion commands over industrial Ethernet, providing deterministic positioning for assembly lines, packaging equipment, and material-handling stations.

It interfaces with plant networks through a Multi-Ethernet port that supports 100Base-TX signaling and is wired via an RJ-45 8-pin connector. For discrete sensing, the unit carries 14 digital inputs. It monitors process variables with 2 analog inputs, and it can drive actuators through 2 analog outputs whose granularity reaches 6 mV/Incr. Four probe inputs capture edge-triggered position events for synchronization tasks. Each axis reads position data by means of a Multi-Encoder Interface, allowing different encoder formats to coexist on the same board. Four optional slots accept add-on cards for further communication or storage.

The board also handles output timing and local operator interaction. Each analog channel updates in 750 µs, supporting fast torque or pressure loops. The front-mounted Advanced Control Panel supplies parameter access, diagnostics, and local jogging without external tools. Machine flexibility is increased by 8 configurable digital I/O that can be programmed as status bits, drive enables, or fault resets. Functional safety is integrated; both axes are protected by Safe Motion, enabling certified stop and limited-speed functions without additional relays. The unit mounts as a pluggable module within multi-axis drive systems and fits into the power section of the drive stack.
