Product Description:

The CDB01.1C-SE-ENS-ENS-EN2-MEM-S2-S-NN-FW is a modular control card in the CDB Control Units series from Bosch Rexroth Indramat. Serving as the central command layer inside IndraDrive systems, the card coordinates drive functions and exchanges real-time data between the drive and higher-level automation controllers. Within a multi-axis drive assembly, it links the power electronics, feedback channels, and control logic so coordinated motion can be handled from one module. Operators interact through a single-line control panel that shows status and diagnostic codes without requiring an external HMI.

The unit manages motion for 2 independent drive axes, so one board can control two axes in compact machines. Command traffic moves over the SERCOS II fiber-optic link, giving deterministic cycle times for position, velocity, and torque commands. This arrangement supports synchronized updates during closed-loop operation and helps the drive respond consistently to changing motion demands. During startup, the converter draws a typical inrush of 6 A, and the surge is limited to a 60 ms pulse so upstream fuses are not overstressed. Once energized, the control electronics draw only 9 W of base power, which helps keep cabinet heat low. The board incorporates Safe Motion, allowing certified speed and position monitoring directly on the drive. Encoder slots 1 and 2 accept ENS feedback signals for incremental or absolute transducers, letting both axes report precise position to the control loop.

A dedicated MEM emulation slot reproduces encoder data for external devices. The channel can stream position words at up to 1 MHz in either SSI or incremental format, and it operates entirely from the card's internal supply so no external MEM power is required. This output is useful when another device needs copied position data without a separate encoder splitter. For auxiliary feedback, input 3 supports the EN2 protocol and is powered from a stable 5 V rail, while the ENS inputs rely on a separate 12 V source to isolate them from logic circuitry. This separation of supply domains helps simplify wiring when different feedback formats are used on the same drive platform.
