Product Description:

The CDB01.1C-SE-ENS-EN2-EN2-NNN-S1-S-NN-FW is a drive controller sub-module produced by Bosch Rexroth Indramat for the CDB Control Units series. Installed in an IndraDrive cabinet, the board handles command processing, feedback evaluation, and fieldbus exchange for multi-axis servo systems used in automated handling, packaging, and machining equipment. It occupies one slot on a power section yet provides the intelligence needed for closed-loop motion, diagnostic reporting, and integrated safety handling within the overall automation architecture.

The unit’s electronics are energized from a DC 24 V control supply, and its quiescent draw of 9 W contributes to cabinet thermal loading. Real-time control data is exchanged over SERCOS II, giving deterministic cycle timing for velocity and torque commands. A 100Base-TX service port terminates on an RJ-45, 8-pin connector for access without interrupting the main fieldbus. The analog monitor channel presents a full-scale span of 5 V, suitable for plotting internal variables on an oscilloscope. Position feedback flexibility is delivered by the factory-installed encoder set, identified as ENS + 2×EN2; these modules accept EnDat and incremental signals so one control board can work with several motor types.

The analog channel can source up to 1 mA, preventing loading errors when it drives high-impedance measurement equipment. Digital outputs can deliver 500 mA per point, while the combined group is limited to 1000 mA, which helps protect PCB traces and connected sensors. A secondary RS-232 port supports service communication at rates up to 115 kBaud for legacy tools. Integrated Safety Technology I/O supervises STO or SS1 chains, and an external 1.6 A feed powers its relay logic independently of the main supply. The board exchanges control, feedback, and safety signals with adjacent drives and plant-level controllers through these connections.
