Product Description:

The CDB01.1C-S3-EN2-EN2-EN2-NNN-S2-S-NN-FW is a modular control unit produced by Bosch Rexroth Indramat for the CDB Control Units series. Installed in IndraDrive power sections, it supervises motion axes, handles fieldbus traffic, and links safety functions to actuators on the plant floor. By combining feedback evaluation, communication, and safe shutdown logic in one card, the device simplifies cabinet layouts for multi-axis automation lines.

This control card draws only 9 W of base power, which helps limit cabinet heat when the drive is enabled but idle. Real-time axis commands are exchanged over SERCOS III, allowing deterministic cyclic data on standard Ethernet cabling. The onboard digital output channel sources up to 500 mA, which is adequate for contactors or signal lamps driven directly from the board. Internal position evaluation uses a secondary 5-volt rail, and the En2 logic consumes 350 mA while operating at a regulated 5.0 V to maintain encoder integrity. When the unit powers up, its supply can draw a surge that lasts up to 60 ms. During that event, the typical inrush reaches 6 A, so the connected supply path must tolerate the temporary current rise.

External I/O electronics are referenced to an isolated control supply of DC 19.2 to 30 V, providing flexibility for 24-volt plant buses. A service connection is available through the RS-232 port, which operates from 9.6 to 115 kBaud for parameter access and serial diagnostics. The board supports EnDat 2.1, 1 Vpp, and 5 V TTL encoder formats, allowing mixed feedback types on adjacent axes. Integrated safety functions conform to the Safe Motion platform and are wired through a D-Sub 9-pin female connector. Two RJ-45 8-pin sockets carry the SERCOS ring for network continuity between connected drive nodes.
