Product Description:

The CDB01.1C-SE-ENS-EN1-EN2-NNN-L1-S-NN-FW control card comes from Bosch Rexroth Indramat and fits within the CDB Control Units series. The unit is inserted into IndraDrive power sections and supplies the command and feedback logic for two servo axes used in industrial automation. By housing axis processing, fieldbus communication, and encoder evaluation on a single board, it serves as the central coordinator between motion profiles configured by the PLC and the power electronics that energize the motors.

At the signal level, the board supports 2 axes, and each analog command channel presents an input resistance of 160 kΩ to keep sensor loading low. Communication with higher-level controllers is carried over the SERCOS interface, allowing deterministic real-time data exchange. A form-C relay is integrated for auxiliary switching tasks and is rated for DC 1 A at up to DC 30 V, enabling direct control of brakes or contactors. Motor feedback is connected through the IndraDyn/Hiperface/1 Vpp/TTL interface, and additional inputs accept HSF/RSF transducers with an 8 V feed as well as EnDat 2.1 or 1 Vpp/TTL devices with a 5 V feed, giving flexibility when mixing encoder formats.

Within the cabinet, the module occupies a footprint of 322.6 mm in height, 49.5 mm in width, and 103 mm in depth, so neighboring drive sections can be sized accordingly. The hardware complies with the Starting Lockout safety option that inhibits unintended motion until an enable signal is received. A front-panel RJ45 socket offers diagnostic access through an unbuffered RS-232 service port, while a second header carries the master SERCOS fiber. The relay’s 30 V load rating and the isolated encoder supplies reduce the need for external interface boards. Screw-clamp terminals handle 5 V, 8 V, and 12 V encoder power, and the shield rail ties feedback grounds to the chassis to lower noise.
