CDB02.1B-ET-EC-EC-EM-S5-S5-EM-NN-FW

The CDB02.1B-ET-EC-EC-EM-S5-S5-EM-NN-FW, Bosch Rexroth Indramat, CDB Control Units form a versatile double-axis control section within the Rexroth IndraDrive ecosystem. This specific CDB02 module leverages MultiEthernet as its Master Communication backbone and seamlessly integrates into SERCOS III or EtherNet/IP networks. Designed as a BASIC control section, it is optimized for precise motion tasks and features a compact, rail-mount design that eases installation in confined cabinets. With two dedicated multi-encoder ports and an encoder emulator interface, the unit addresses both absolute and incremental feedback requirements with high fidelity.

At the heart of its interface suite are Interface 1: Multi-encoder interface and Interface 2: Multi-encoder interface, each supporting dual-channel feedback, plus Interface 3: Encoder Emulator for flexibly simulating absolute or incremental encoders. The unit offers Safe Motion Axes on both safety technology channels, delivering functional safety up to SIL 3 or PL e when paired with appropriate safety bus modules. Its electrical profile includes a Maximum Inrush Current: 5 A spike limitation and a Maximum Pulse Width: 1 ms timing resolution to protect downstream power electronics. Rated for category C3 per IEC 61800-3, the CDB02.1B module demands external line filters and industrial-grade environments to prevent EMI. In addition, the unit tolerates up to Mounting Cycles: 20 rail insertions and removals before mechanical wear may impact performance.

Engineered for seamless integration, this CDB Control Unit slots directly into standard Rexroth IndraDrive power sections, unlocking synchronized multi-axis topologies in handling, machine tool, and printing applications. Its robust safety features and precise encoder handling ensure reliable operation in high-precision environments. The compact footprint and standardized interfaces reduce commissioning time and spare parts inventory, making the CDB02.1B-ET-EC-EC-EM-S5-S5-EM-NN-FW an ideal choice for OEMs demanding both flexibility and certified safety in motion control systems.
