Product Description:

The CDB01.1C-S3-ENS-ENS-EN2-MA1-S2-S-NN-FW control card is produced by Bosch Rexroth Indramat for the CDB Control Units series. The module inserts into an IndraDrive power section and supplies the logic that coordinates position, velocity, and torque loops for two synchronized axes in industrial automation machines. By processing encoder returns, fieldbus commands, and local analog references, it closes the feedback loop between higher-level PLCs and inverter electronics so that drives execute deterministic motion profiles required in conveyors, packaging equipment, material-handling stations, and other synchronized machine sections.

Each motion channel is configurable because the card supports 2 axes and presents 2 x ENS encoder inputs powered from a dedicated 12 V source. For auxiliary feedback, a combined EnDat 2.1 / 1 Vpp / 5 V TTL socket is available, allowing mixed absolute or incremental sensors to be attached. Command data reach the unit over the real-time SERCOS III interface, while a Standard control panel on the front edge offers local parameter access. Analog scaling tasks are handled by the MA1 option; it furnishes two input and two output channels with 12-bit resolution, letting the drive process velocity potentiometers or transmit torque references to external devices. The En2 encoder supply delivers 5 V for secondary measuring systems and keeps the reference electronics isolated from the main power layer.

The RS232 port transfers parameter sets at up to 115 kBaud and maintains signal integrity across a cable length of 15 m. A front-mounted MultiMediaCard slot stores axis parameters locally, allowing the card to retain application data on removable media instead of relying only on internal memory. Functional safety is implemented at drive level by the Safe Motion package, which links to external emergency circuitry through a 9-pin female D-Sub connector. This front-access arrangement keeps communication, storage, and safety connections easy to reach within the drive assembly.
