CDB02.1B-ET-EC-EC-NN-S5-S5-NN-NN-AW

The Bosch Rexroth Indramat CDB02.1B-ET-EC-EC-NN-S5-S5-NN-NN-AW from the CDB Control Units series features Master Communication: MultiEthernet for high-speed data exchange and precision synchronization. This control unit supports a Multi-encoder interface on both Interface 1 and Interface 2, enabling dual-axis feedback and flexible encoder combinations. Designed for demanding production environments, the unit provides deterministic communication cycles and robust handling of feedback signals. Its double-axis architecture simplifies integration with two HMD01 power sections for simultaneous control of dual motor axes without additional hardware changes.

The module’s Interface 3: Not Equipped status highlights its streamlined functionality, focusing resources on the primary encoder channels and minimizing configuration complexity. Thanks to the integrated MultiEthernet backbone, the CDB02.1B-ET-EC-EC-NN-S5-S5-NN-NN-AW maintains real-time control loops with jitter well below microsecond thresholds. The redundant encoder ports can host a range of Sin/Cos, TTL, or EnDat devices, supporting advanced interpolation and position error correction. Certified safety options for each axis (Safe Motion) ensure deterministic torque shutdown in emergency scenarios, meeting stringent machine safety standards.

Installation and commissioning of the CDB02.1B-ET-EC-EC-NN-S5-S5-NN-NN-AW rely on version-controlled firmware (FWA-INDRV*-MPx-18VRS or higher) loaded via the same MultiEthernet channel, facilitating rapid updates and field diagnostics. The absence of a tertiary encoder port (Interface 3) and the focused dual-encoder design reduce potential failure modes, improving uptime and easing preventive maintenance. This control unit’s robust construction and conductive shipping wrap ensure safe transport and storage, with commissioning reserved for certified personnel to protect the sensitive multi-encoder communication interfaces.
