Product Description:

The CDB01.1C-SE-EN1-EN1-EN2-MEM-NN-S-NN-FW belongs to the CDB Control Units series produced by Bosch Rexroth Indramat. As a modular motion controller, this device interfaces with drives and higher-level PLCs to coordinate axis positioning in packaging lines, printing presses, and assembly machinery. It forms part of the drive stack, handling setpoint calculation, feedback evaluation, and diagnostic reporting so that mechanical axes follow commanded trajectories with tight synchronization. This arrangement allows the control unit to manage coordinated motion and react to changing feedback conditions without requiring a separate standalone motion processor.

During power-up the unit draws a maximum inrush of 6 A, after which the base consumption stabilizes at 9 W. Internal timing tasks are referenced to a base pulse width of 60 ms, allowing deterministic scheduling of control loops. Communication with the drive bus occurs over the SERCOS fiber-optic channel, providing high-speed cyclic data exchange without electrical noise coupling. The hardware supports 2 axes, each with its own current and position controller. A standard front-mounted control panel provides local access to status and parameter sets, while two analog outputs and four digital outputs can be used for process signals, status indication, or trigger functions.

For sensor integration, the first encoder port delivers a Hall or servo feedback supply of 8 V at up to 250 mA. It also provides a 4 kHz resolver carrier and an 18.2 Vpp resolver excitation for legacy transducers. The second encoder channel provides a regulated 5.0 V source with 350 mA capacity for TTL or RS-422 encoders. The MEM interface can output frequencies up to 1 MHz, supporting fine-grained pulse generation for fast position latches. This layout lets the unit process feedback from different encoder types while also supplying pulse data to connected motion hardware.
