Product Description:

The CDB01.1C-SE-ENS-ENS-NNN-MEM-NN-S-NN-FW is a plug-in control card from the CDB Control Units series produced by Bosch Rexroth Indramat. Installed in IndraDrive drive racks, the board acts as the motion processor that links drives with higher-level PLCs through deterministic optical networking. It supervises command generation, feedback acquisition, and safety monitoring, allowing servo axes to follow synchronized profiles in assembly stations, packaging lines, and material-handling gantries. By combining encoder emulation and fieldbus signaling on the same PCB, it reduces component count inside decentralized electrical cabinets.

At the hardware level, the module processes up to 2 axes, enabling twin-drive configurations on one card. Its internal logic draws a base load of only 9 W, while two detachable ENS safety modules add another 6 W when fitted, keeping total power use modest for passive-cooled cabinets. Motion telegrams are exchanged over the SERCOS II interface, and the link uses a fiber-optic ring that resists conducted and radiated noise. Analog monitor channels are digitized with a resolution of 12 bit, and the MEM encoder emulation lets the drive present standardized position data to legacy controls without extra transducers.

Dynamic response is supported by a cut-off frequency of 500 kHz, permitting the current controller to react within microseconds to load disturbances. The integrated encoder power rail supplies 11.6 V at 500 mA, which is sufficient for most incremental or sine-cosine sensors. During energization, the board tolerates an inrush of 6 A, and the related port uses a 120 Ohm termination to help maintain signal integrity. Additional daughterboards consume little energy, as the MEM module needs 2 W and the SE interface board needs a further 2 W, and mechanical coupling to the SERCOS connector requires only 0.6 Nm of torque.
