Product Description:

The CDB01.1C-PB-EN2-EN2-ENS-ENS-S2-S-NN-FW is a modular control unit from Bosch Rexroth Indramat’s CDB Control Units series. It is installed in IndraDrive drive stacks and coordinates motion on two axes through integrated control loops and fieldbus interfaces. By combining feedback decoding, axis logic, and safety circuitry on one card, the unit helps reduce panel complexity in general automation, packaging lines, and material-handling cells. Its dual-axis layout allows one control platform to manage coordinated motion tasks without requiring a separate external motion card.

During operation, the controller’s base demand is only 9 W, so internal heat dissipation remains low. Command data are exchanged over PROFIBUS, allowing deterministic bus cycles that align with the current control interval of 125 µs. This rapid loop supports stable torque control on both axes during dynamic motion. The card provides a digital output stage rated at 500 mA for actuating external indicators or contactors, and one analog monitor channel supplies 5 V at 1 mA for process feedback. Two En2 encoder ports support EnDat 2.1, 1 Vpp, and 5 V TTL signals, and each port is energized from a dedicated supply of 5.0 V / 350 mA. With paired axis control and matched En2 feedback inputs, the unit can support synchronized gantry motion or other coordinated multi-axis functions without additional interface hardware.

Additional feedback is handled by two Ens inputs that accept IndraDyn S, HIPERFACE, 1 Vpp, or EnDat 2.1 formats and are powered by 11.6 V / 500 mA. For discrete control tasks, an onboard relay can switch loads up to DC 24 V / 1 A. Integrated Safe Motion technology is accessed through a D-Sub 9-pin female connector, enabling functions such as STO or SS1 without external relays. Parameter access is handled through the dedicated RS232 service port. The separate En2 and Ens feedback groups allow the unit to work with different encoder signal types on the same controller.
