Product Description:

Bosch Rexroth Indramat produces the CDB01.1C-SE-EN1-EN2-NNN-NNN-S1-S-NN-FW control section for modular drive systems within the CDB Control Units series. Installed in a drive controller rack, this unit serves as the logic core that links motion axes, fieldbus channels, and integrated safety circuits. In industrial automation, it generates reference signals, conditions encoder feedback, and supervises safe torque-off chains so the associated power inverters can modulate servo or spindle motors according to machine commands. Its hardware layout accepts both primary and secondary encoder boards and a communication module.

For continuous operation, the control section draws only 9 W, and an attached communication module adds 2 W; these small figures simplify cabinet cooling and power sizing. At startup, a surge of 6 A lasts just 60 ms, so upstream breakers must tolerate the pulse without tripping. The primary encoder port supplies 8 V to feedback transducers, keeping sensor excitation independent of external rails. Two analog test channels can source 1 mA at 5 V for oscilloscope monitoring without loading the circuitry. These ratings set the electrical limits for the logic section and connected devices during dynamic machine states.

The communication slot ships with the real-time SERCOS interface, enabling deterministic telegrams between the controller and multi-axis drives. Position feedback remains flexible because the first encoder port accepts the Resolver / HSF option, while the second port supports digital formats such as EnDat, 1 Vpp, or 5 V TTL. Primary wiring terminates on a D-Sub 9 safety connector, which provides a compact connection point at the module face. Safety circuits draw from a dedicated DC 24 V rail, with group output limited to 0.5 A and inputs supervised at 3 mA.
