Product Description:

The Bosch Rexroth Indramat CDB01.1C-SE-ENS-EN2-NNN-ENS-S1-S-NN-FW is a plug-in control section from the CDB Control Units series. It mounts on an IndraDrive power module and supplies the command logic that closes position, velocity, and torque loops. Within an automation cell, it translates motion profiles from the machine PLC into synchronized drive signals while simultaneously processing encoder feedback and supervising integrated safety circuitry. This architecture separates low-voltage electronics from the high-power stage and reduces enclosure depth.

The section offers 2 analog outputs that can stream process variables to external meters. Internal electronics consume only 9 W, minimizing cabinet heat. Real-time communication with the power stage and neighboring axes is handled through SERCOS II, keeping cyclic data deterministic. When mains is applied, an inrush limiter restricts current to 6 A for 60 ms, protecting supply fuses. The primary encoder link follows the ENS format, and a dedicated EN2 port is reserved for secondary feedback. One normally open relay contact reports drive-ready status to interlocks. Safety wiring terminates on a D-Sub 9 connector, and the built-in S1 module can source a 24 V / 0.5 A signal to external contactors.

Secondary feedback electronics draw 350 mA from a regulated 5.0 V rail, while the separate ENS track is powered by 12 V to isolate reference grounds. A maximum bus speed of 16 MBaud keeps the SERCOS ring synchronized to sub-millisecond accuracy across multi-axis systems. For stop functions, the board routes a DC 24 V / 1 A safety relay output directly to motor contactors, eliminating the need for an external module. The available encoder resources support high-resolution SinCos sensors used on precision positioning axes.
