Product Description:

Bosch Rexroth Indramat manufactures the CDB01.1C-SE-EN2-EN2-NNN-NNN-L1-S-NN-FW, a control card from the CDB Control Units series. The card plugs into IndraDrive power sections and coordinates servo axes, acting as the logic layer that links fieldbus commands to current loops, encoder feedback, and integrated safety functions within industrial automation cells. As a modular component, it governs velocity, position, and torque loops for drives used in packaging lines, material handling systems, and process machinery.

The board supports 2-axis operation, and each axis is commanded over the SERCOS II fiber-optic ring. A current loop period of 125 µs keeps torque control tight during rapid transitions. Feedback arrives through 2 × EnDat 2.1 / 1 Vpp / 5 V TTL interfaces, and the board supplies 350 mA at a regulated 5.0 V for external encoders. Two analog outputs can feed proportional valves or external drives. Cabinet heating stays low because the base board draws only 9 W. One normally open relay contact handles ready signaling, and the drive can be enabled once the 24 V, 3 mA safety line is closed. This arrangement lets the card supervise coordinated motion channels within the same drive platform.

At the network level, the minimum SERCOS telegram period is 1000 µs, which supports deterministic update timing in multi-drive topologies. Initial energization draws 6 A during a 60 ms inrush window before settling to nominal power consumption. A D-Sub 9 female connector routes the safe torque off circuit, and the integrated safety function uses Starting Lockout to inhibit gate firing until the external chain is cleared. For diagnostic access, the board retains a legacy RS232 port that streams parameter data without occupying the real-time bus. The dedicated safety connector keeps the interlock circuit separate from the motion network, which helps keep cabinet wiring organized.
