Product Description:

The CDB01.1C-PB-ENS-EN2-EN2-MA1-S1-S-NN-FW is a plug-in control section manufactured by Bosch Rexroth Indramat for use in the CDB Control Units series. Mounted on a power module, it supplies logic processing, fieldbus access, and integrated safety for multi-axis drive assemblies on conveying, packaging, and machining lines. By combining local motion sequencing with upstream communication, the card serves as the command layer between the machine PLC and the inverter stage. This layout keeps control, communication, and safety functions on one removable module.

The board draws its primary logic from a DC 24 V control rail and distributes auxiliary energy through dedicated rails of 5 V for the EN2 encoder socket and 12 V for the ENS supply. A startup inrush of 6 A is specified, so the supply feeding the unit must tolerate that brief surge before settling to the steady-state demand of 32 W. Two analog input channels and two analog output channels are provided on the MA1 option, allowing proportional setpoint and feedback handling without external converters. The safety I/O rails accept 24 V at 3 mA for inbound signals and source 24 V at 0.5 A on the outbound side, enabling direct connection to contactors or light-curtain relays.

Network access is provided through a 100Base-TX engineering port for setup and service access, while motion commands reach the unit over a PROFIBUS interface terminated by a D-Sub 9 Female connector. Safety channels are routed on a second D-Sub 9 so dual-channel wiring stays separate from standard fieldbus lines. A maximum internal pulse width of 60 ms is allowed for time-critical control signals, helping the drive respond promptly within a PLC cycle. The analog inputs and outputs use a common 12-bit resolution, so command and feedback paths have matching conversion precision.
