Product Description:

The CDB01.1C-SE-EN1-EN1-EN2-EN2-L1-S-NN-FW control section is produced by Bosch Rexroth Indramat for the CDB Control Units series. It installs on an IndraDrive power module and coordinates drive, feedback, and fieldbus data within multi-axis automation. By combining encoder evaluation, digital I/O processing, and fast communication in a single plug-in card, the unit simplifies cabinet wiring and streamlines motion sequencing in production machinery.

The control card exchanges bus data over a 16 MBaud fiber-optic SERCOS interface, so cycle times remain short even when multiple axes are synchronized. Up to 22 digital inputs are accepted through optically isolated channels with an input resistance of 160 kΩ. Analog monitoring signals leave the card after a 10 µs digital-to-analog conversion, and each step is quantized at 19.5 mV/inc to support fine torque or speed trimming. During power-up, the module can draw a peak of 6 A as inrush before stabilizing. When all processing, encoder supply, and I/O loads are active, electrical demand reaches 37 W, a value used for cabinet thermal calculations. A pulse-train output with a 60 ms minimum width is available for time-critical actuator control, while two resolver/HSF channels permit non-incremental feedback monitoring.

The card supports two 5 V encoder channels for incremental feedback, and the dedicated EN2 interface delivers 350 mA at 5 V while tolerating a 35 Ω load, so high-density linear scales can be powered directly. Logic sections idle at 9 W, reducing dissipation when motion is disabled. A built-in reference generator provides 5 V, 1 mA on the analog output, suitable for biasing drive amplifiers or sensor bridges. Digital input evaluation asserts once the lines exceed 15 V, a level that improves noise immunity in electrically harsh environments.
