Product Description:
The CDB01.1C-S3-ENS-EN2-EN1-NNN-NN-S-NN-FW control section is produced by Bosch Rexroth Indramat as part of the CDB Control Units series. It forms the logic core inside an IndraDrive power module, where it handles sensor feedback, fieldbus messaging, and drive diagnostics for multi-axis automation. By accepting high-speed communication and generating precision analog references, the unit directs inverter stages that move motors, actuators, and machine tools in industrial production lines. Its compact card format mounts directly on a power section, reducing wiring inside the cabinet. This arrangement keeps signal processing close to the power stage and helps simplify internal connections within the drive assembly.
At idle, the board draws a base power consumption of 9 W, minimizing cabinet heat while keeping the internal processor and I/O active. Two configurable analog outputs are available; each can deliver up to 1 mA or a maximum swing of 5 V, allowing proportional speed or pressure commands to external devices. Network traffic is carried through a shielded RJ-45 8-pin connector that complies with the IEEE 802.3 physical layer, while cyclic real-time motion data is exchanged over SERCOS III. This dual-port topology lets the control unit handle standard Ethernet diagnostics alongside deterministic drive communication without additional hardware. The layout also supports integration with surrounding automation components that rely on both service access and time-critical motion exchange.
The remaining interfaces supply transducers and encoders directly from the board. For the first encoder channel, the HSF line can source 250 mA at 8.0 VDC, and its resolver carrier operates at 4 kHz with an amplitude of 18.2 Vpp for noise-immune position feedback. The second encoder port offers 5.0 VDC at 350 mA and tolerates a load of 35 Ω, matching low-impedance incremental sensors. The ENS safety channel furnishes 11.6 V at 500 mA for redundant monitoring devices. During power-up, the control unit briefly draws an inrush of 6 A, so input fusing and wiring must accommodate that surge. Separate onboard supplies let connected feedback devices operate without requiring an additional auxiliary interface board.
