Product Description:

The CDB01.1C-S3-EN2-EN2-EN2-EN2-S2-S-NN-FW is a control section produced by Bosch Rexroth Indramat and belongs to the CDB Control Units series. Installed in drive cabinets, it serves as the command layer for multi-axis motion platforms in industrial automation. The unit converts network commands into drive signals while accepting encoder feedback, enabling machinery to follow motion profiles and trigger safety functions when operating limits are reached. This role allows one module to coordinate motion behavior, feedback handling, and communication tasks without requiring separate control hardware for each connected axis.

The device supervises 2 coordinated drive axes and exchanges real-time data over SERCOS III, giving deterministic cycle times for position and velocity loops. Each axis can be issued an analog reference, and the analog channel delivers 1 mA of source current at a programmable span centered on 5 V, allowing external meters or controllers to read actual values. Encoder data enter through the EnDat 2.1, 1 Vpp, or 5 V TTL interface, and the En2 feedback port is routed to a D-Sub 15-pin receptacle. That port tolerates a minimum load of 35 Ω and supplies the sensor with 350 mA. The regulated En2 rail is 5.0 V when sense lines are used and 5.1 V when they are not, which helps maintain stable feedback operation across different cable arrangements.

The control card draws its logic power from an external 24 V DC source, and the internal distribution requires up to 1.1 A, so cabinet supplies must accommodate that continuous load. Integrated Safe Motion functionality supervises limit switches, velocity windows, and encoder plausibility without requiring separate safety relays for those monitoring tasks. For setup or service access, a built-in RS232 serial port provides parameter communication when a fieldbus connection is unavailable. The combination of local sensor supply, discrete I/O support, and high-speed network communication on one board helps reduce panel wiring and keeps the control layout easier to organize inside the cabinet.
