Product Description:

The CDB01.1C-S3-ENS-ENS-EN2-NNN-S2-S-NN-FW control section is manufactured by Bosch Rexroth Indramat for the CDB Control Units series. This plug-in board acts as the motion-processing core inside modular IndraDrive servo amplifiers, coordinating multiple drive axes and interfacing with field networks, encoders, and I/O resources. In industrial automation, it generates real-time current, speed, and position commands so that connected inverters can execute precise and synchronized motor movements on production machinery.

At the network level, the board communicates with higher-level PLCs over SERCOS III, allowing deterministic cyclic data exchange for both axes. Torque loops are refreshed every 125 µs, a current-control period that supports tight velocity regulation. Two differential encoder ports rated 2 x Rexroth/HIPERFACE/1Vpp handle primary feedback, while a secondary channel accepts EnDat or 1 Vpp sine/TTL signals for redundant position tracking. One analog input and two analog outputs permit external reference scaling or drive status reporting. The module draws only 9 W during steady operation, yet the supply must tolerate an inrush of 6 A that can last up to 60 ms. The internal logic supervises both axes simultaneously.

The local interface set is completed by a 1 N/O relay contact for fault signaling, one RS232 maintenance port, and a standard Control Panel that provides parameter access without additional accessories. Functional safety is implemented through Safe Motion, and two safety slots allow compatible option modules to extend this feature set. Because the Axis 2 secondary slot is not equipped, the second channel can be customized later with bus or encoder hardware if needed. The board also uses an uninterruptible low-power logic supply and fits directly into IndraDrive power sections.
