Product Description:

The CDB01.1C-SE-EN2-EN2-ENS-ENS-S2-S-NN-FW is a modular drive control card produced by Bosch Rexroth Indramat for the CDB Control Units series. When fitted into an IndraDrive power section, the card supplies command processing and fieldbus communication for servo axes in automated machinery. By generating setpoints, evaluating feedback, and forwarding safety signals, it coordinates torque, speed, and position loops so motion tasks can be integrated into PLC-based production workflows.

It manages 2 axes on a single board, enabling compact dual-channel drive arrangements without an external controller. Motion commands travel through SERCOS II, a deterministic fiber-optic ring, and the card sustains a data rate of 16 MBaud, permitting short cycle times for tightly synchronized profiles. For analog signaling, one voltage output delivers 5 V at its reference terminal, while the corresponding current output is limited to 1 mA; these low-level channels are typically used for sensor excitation, analog diagnostics, or legacy drive enable lines. Each axis also receives dedicated En2 and Ens encoder supplies and digital outputs, which are separated from the analog section to minimize noise.

Electrical loading remains moderate; the board draws 9 W during normal operation and withstands an initial inrush of 6 A when the supply bus is energized. Integrated Safe Motion circuitry monitors encoder feedback and drive status so certified shutdown paths can be executed without an external safety relay. For service tasks, the front panel exposes an RS232 port, allowing parameter access with standard serial tools even when the fieldbus ring is unavailable. Additional transistor outputs supply up to 1 A combined for contactor coils or status lamps, and pulse-width timing is fixed at 60 ms to support reliable actuation.
