CDB02.1B-ET-EC-EC-NN-L3-L3-NN-NN-NW

The Bosch Rexroth Indramat CDB02.1B-ET-EC-EC-NN-L3-L3-NN-NN-NW control unit from the CDB Control Units series delivers high-performance drive management in a compact double-axis platform. This extended scope control section is built to Design 1 standards and incorporates dual multi-encoder interfaces (Interface 1: Multi-encoder interface and Interface 2: Multi-encoder interface) for precision feedback on both axes. Communication is handled via native Master Communication: MultiEthernet, supporting seamless integration into modern fieldbus architectures. The module operates on a 24 V DC supply and draws only 23 W at nominal load.

Reliability and safety are at the core of the CDB02.1B design: two dedicated safety technology axes each feature a Safe Torque Off (STO) interface to prevent unintended motor activation. Inrush currents are limited to 5 A maximum, and pulse signals maintain a controlled width of up to 1 ms for crisp, deterministic command execution. Status and bus activity are displayed via integrated LED indicators, simplifying diagnostics on sercos III, EtherCAT, EtherNet/IP, or PROFINET IO networks. Classified as C3 under IEC 61800-3, this unit is optimized for industrial deployment when used with appropriate line filters.

Engineered for global distribution with a standard one-year warranty from Wake Industrial, the CDB02.1B-ET-EC-EC-NN-L3-L3-NN-NN-NW control unit streamlines integration into IndraDrive power sections and broader automation systems. Its consistent form factor across the CDB family enables rapid rack mounting and hot-swap replacement, reducing downtime. With Bosch Rexroth’s proven track record in drive technology, this control section is an ideal choice for applications demanding compact multi-axis control, robust safety integration, and high-speed Ethernet communication.
