Product Description:

The CDB02.1B-ET-EC-EC-NN-SB-SB-NN-NN-AW belongs to the CDB Control Units series produced by Bosch Rexroth Indramat. This dual-axis control card plugs into an IndraDrive power section and supervises torque, speed, and position loops for two servo axes. By combining encoder evaluation, analog acquisition, and network communication on one board, the unit serves as a compact motion processor that links field devices to upper-level automation platforms in packaging, handling, or machining lines. Its dual-axis layout allows one control unit to coordinate paired motion tasks such as synchronized feeders, transfer axes, or matched servo movements within the same machine section.

Communication to supervisory equipment is handled over Multi-Ethernet, so the card can operate on several industrial Ethernet dialects without additional gateways. Two differential analog input channels accept signals in the ±10 V range, allowing direct feedback from strain gauges or pressure sensors. For discrete state monitoring, the controller provides 14 digital inputs that capture limit switch or proximity data every cycle. System tailoring is simplified because 4 optional slots accept expansion modules for fieldbus, encoder, or memory functions. Each ±10 V analog output is refreshed in 750 µs, which supports fast closed-loop velocity or force regulation. This combination of network access, analog handling, and configurable expansion helps the control unit fit machines that mix motion control with external sensing and status signals.

Further customization is available through 8 configurable digital I/O points that can be mapped to enable, brake release, or cam latch tasks. Four probe inputs capture position latches with microsecond timing, which is useful for punch or registration marks. The dual multi-encoder ports deliver 500 mA at 12 V, eliminating the need for an external sensor supply while powering absolute or incremental feedback devices through the Multi-Encoder Interface. Functional safety is integrated on both axes via the Safe Motion Bus, permitting certified stop, speed, and direction functions to be executed over the same real-time channel that carries standard motion data. This arrangement supports compact cabinet design by reducing the number of separate interface modules needed for feedback, signal handling, and safety-related motion functions.
