Product Description:
The CDB01.1C-ET-EN1-EN1-EN2-EN2-NN-S-NN-FW is a plug-in control unit produced by Bosch Rexroth Indramat for the CDB Control Units series. Inserted into an IndraDrive power section, it handles command processing, feedback evaluation, and fieldbus exchange so the drive can position or regulate a connected axis. In an automation line, this board supplies encoder power, issues analog setpoints, and provides relay signaling, allowing coordinated motion without adding a standalone PLC communication card.
The board draws a base power of 9 W from the DC bus, a value that stays constant while logic tasks run. Two analog outputs deliver 1 mA at a nominal 5 V, giving a simple voltage or current reference for external actuators. A combined 1000 mA low-voltage rail supports sensors and status LEDs. Control communication is handled through a Multi-Ethernet interface, so it can support protocols such as EtherNet/IP or PROFINET. Option slots 1-2 carry the EN1 module; its resolver supply is 18.2 Vpp with a sine carrier frequency of 4 kHz, matching standard brushless motor resolvers. Slots 3-4 hold the EN2 module that powers digital encoders, and the dedicated EN2 rail can source 350 mA for high-resolution feedback devices without external power taps.
The second encoder path includes a sensed supply of 5.0 VDC so line losses can be detected and compensated. Real-time data to higher networks is passed through an ET port that meets the 100Base-TX standard. During power-up, the capacitors admit energy for a maximum of 60 ms, and the resulting inrush peaks are limited by design to a typical 6 A. A form-C relay contact on the front edge can switch up to 1 A for error chains or motor contactors. The unit carries no integrated safety technology, so any required safe torque-off function must be provided externally.
