Product Description:

The CDB01.1C-SE-ENS-ENS-NNN-NN-S1-S-NN-FW is a plug-in control board built by Bosch Rexroth Indramat for the CDB Control Units series. Installed inside a compatible drive controller, the board supervises signal processing, axis coordination, and network exchange so that servo inverters can be integrated into automated machinery with minimal wiring. By translating fieldbus commands into real-time drive signals, it enables precise position, velocity, and torque control on factory lines, packaging cells, and material-handling stations.

This board governs 2 axes, allowing one control unit to manage paired motion channels in a compatible drive system. Command data reach the unit through the SERCOS II fiber-optic interface, while a legacy serial port supports service communication. Each analog command input is terminated by 160 kΩ; the high resistance prevents loading of upstream transducers, and 1.23 mV per increment provides fine input resolution. On the output side, the controller delivers a regulated 5 V reference with 19.5 mV incremental steps across a 5 kΩ load, allowing proportional speed or torque setpoints to be sent to external devices. Digital status lines draw only 3 mA per input, preserving sensor life, whereas discrete outputs can source up to 500 mA for actuators such as contactors or indicator lamps. The encoder interface accepts 120 Ω differential signals and filters feedback up to 400 kHz TTL so closed-loop calculations remain accurate at high motor speeds.

Additional feedback resources are supported by a 120 Ω input resistance for EnDat and Hiperface encoders and a supply rail of 11.6 V that can deliver 500 mA to transducers without external power packs. The RS-232 port communicates at a peak rate of 115 kBaud, allowing quick parameter transfers. The same logic section can capture 400 kHz incremental inputs, while safety circuits receive 1.6 A to drive force-guided relays.
