Product Description:
The CDB02.1B-ET-EC-EC-EM-NN-NN-EM-NN-FW control unit is produced by Bosch Rexroth Indramat and belongs to the CDB Control Units series. Intended for cabinet-mounted IndraDrive assemblies, the device supervises dual servo motion and forwards position, velocity, and torque commands to matched inverter stages. By unifying feedback, I/O, and network communication on a single board, it streamlines the integration of multi-axis machinery used in packaging, machining, and material-handling cells.
Control power is supplied at 24 VDC, so the card can share a low-voltage rail with sensors, brakes, and relays. It manages 2 axes, each driven by an independent current loop inside the connected power module. Discrete machine states arrive on 14 digital inputs, while process variables such as tension or flow are captured through 2 analog inputs sampled by the drive. Eight terminals designated as 8 configurable digital I/O can be parameterized per application as outputs for solenoids or as additional inputs, reducing cabinet rewiring. Two analog outputs reproduce scaled speed or torque references to a supervisory PLC. Four probe inputs latch axis position on external edge triggers for cut-to-length or print-mark registration. Encoder connectivity is versatile because two emulation ports generate incremental or SSI signals for legacy controllers, and two multi-encoder interfaces accept absolute, resolver, or EnDat feedback devices. The unit has no integrated safety functions, so any STO or SS1 logic must be implemented externally.
All traffic passes through a Multi-Ethernet interface that conforms to IEEE 802.3. Firmware exposes logical channels for sercos III, EtherCAT, EtherNet/IP, and PROFINET IO, allowing one control unit to fit diverse fieldbus topologies through parameter changes. The unit’s unpacked mass is 0.480 kg, which helps when space is limited in dense control cabinets. Minimum drive firmware level MPx-18VRS is required for diagnostic trace and autotune features. Coupling with the HMD01 power section supplies the PWM output stage, and the lack of onboard safety circuitry keeps the control card compact.
