Product Description:

The CDB01.1C-PB-ENS-ENS-EN2-MEM-NN-S-NN-FW is a plug-in control section from the CDB Control Units series manufactured by Bosch Rexroth Indramat. Designed for modular drive systems, it mounts on power sections of the IndraDrive platform and manages real-time motion, feedback processing, and fieldbus communication for two synchronous or induction axes. By coordinating command processing, feedback evaluation, and network exchange, the unit serves as the central logic layer that links servo drives with higher-level PLC controllers in industrial automation cells.

The unit supports 2 coordinated drive axes, each monitored through the ±10 V differential analog input that presents a 160 kOhm input impedance to limit source loading. Command voltages are regenerated by a 5 V, 1 mA analog output for external reference loops. For discrete signaling, it furnishes 22 optically isolated digital inputs and 4 transistor outputs, enabling position latching, limit detection, and status annunciation. Two ENS ports, one EN2 port, and one MEM port form the feedback cluster, allowing mixed encoder protocols to be processed without additional interface cards. A 24 V relay channel rated at DC 24 V, 1 A provides drive-ready or fault signaling to upstream safety relays.

System power for the logic and I/O stage is delivered by the DC 19–30 V, 1.1 A auxiliary supply, while incremental encoder electronics are fed with ENS 12 V; EN2 5 V rails internally derived from the board. Host networking is handled over PROFIBUS-DP, accessed through a DIN-style 9-pin female D-Sub connector; a repeater header sources +5 V (±10%) at 75 mA for line extenders. The card occupies 103 mm of cabinet depth and rises to 322.6 mm in height when seated in the power section. No integrated safety option is fitted, so external safe-torque-off devices must be used.
