Product Description:

The CDB02.1B-ET-EC-EC-NN-S5-S5-NN-NN-AW is a plug-in control section produced by Bosch Rexroth Indramat for the CDB Control Units series. Installed on IndraDrive power modules, the unit acts as the central processor for servo drives, coordinating position, velocity, and diagnostic functions in multi-axis machinery and automated assembly lines. It is designed for IndraDrive modular inverters and serves to process command setpoints, evaluate feedback signals, and forward control data to connected motors, enabling deterministic motion sequences in industrial automation cells.

The control card can manage 2 axes, and each channel receives position triggers through 14 digital inputs plus 8 configurable I/O points that can be assigned as additional inputs or outputs. Two ±10 V signal paths accept feedback from external sensors, giving the unit 2 analog inputs. Corresponding command voltages are delivered on 2 analog outputs, each scaled in 24 mV increments and specified for a 2 kΩ minimum load to maintain linearity. Motion programs and diagnostic telegrams move over the built-in Multi-Ethernet port, while process data sampling can be synchronized with four probe inputs for edge capture.

An internal power budget of 6 W encoder supply supports two high-resolution feedback channels. These channels draw up to 500 mA at 12 V or 500 mA at 5 V, allowing dual multi-turn encoders to be powered through the board’s 2 × multi-encoder interfaces without external converters. Real-time data are forwarded to higher-level controllers through the ET-Link port that follows the 100Base-TX standard, and a Multi-Ethernet stack handles EtherNet/IP, PROFINET, and EtherCAT telegrams concurrently. Functional safety is integrated through Safe Motion monitoring on each axis. Four optional slots accommodate extra modules so the control card can adapt to application-specific fieldbus or I/O extensions.
