Product Description:

The CDB01.1C-SE-ENS-EN2-NNN-NNN-S1-S-NN-FW is a plug-in control section manufactured by Bosch Rexroth Indramat for the CDB Control Units series. Installed on a compatible power module, it manages command processing, encoder evaluation, and integrated safety channels for multiple servo axes. It serves as the communication and logic core between the drive hardware and supervisory PLCs, enabling deterministic motion sequences and coordinated fault handling across conveyor, packaging, and machining stations. In a control cabinet, it occupies the dedicated control slot, which allows the heavier power electronics to be serviced or replaced separately from the logic section. That arrangement helps preserve the installed power stage and field wiring when only the control electronics need attention or a configuration change.

During power-up, the board draws a base inrush current of 6 A for 60 ms, so feeder protection must tolerate this brief surge before the load settles. After startup, continuous demand is only 9 W, which helps limit heat generation inside the enclosure. All cyclic drive data moves over SERCOS II fiber optics, providing fixed telegram timing for precise velocity and position loops across linked axes. The control section also handles local signal exchange for machine operation, while primary position feedback reaches the unit through a 15-pin D-Sub female connector that carries incremental or absolute encoder signals and a stabilized 12 V sensor supply.

Secondary feedback is handled by the ENS socket, which supports a cable length of 75 m with sense leads; the line is powered from a 5.0 V rail capable of 350 mA. Programmable status relays are rated at 24 V / 1 A DC for driving contactors or indicator lamps, giving the control section a direct interface to external status circuits. The collective digital outputs may deliver up to 500 mA, and input channels latch once 15 V is present. Safety Technology I/O uses a D-Sub 9 female connector, and its circuits accept 24 V at 3 mA for inputs while sourcing 24 V at 0.5 A for outputs to connect light curtains, emergency stops, and gate interlocks.
