Product Description:
The CDB01.1C-S3-ENS-ENS-NNN-MA1-S2-S-NN-FW control section is produced by Bosch Rexroth Indramat within the CDB Control Units series. It is installed in modular drive systems to coordinate axis functions, route feedback, and deliver fieldbus connectivity between servo inverters and the higher-level PLC in industrial automation. A single-line display provides local operator feedback and shows status codes during startup and runtime.
This version uses a RJ-45 (8-pin) connector to join the drive ring, and the interface carries the deterministic Sercos III protocol so cycle times stay consistent. For cabling, the manufacturer specifies CAT5e ITP twisted pair to maintain signal integrity over the Ethernet-based bus. The control section powers sensors and optocouplers through a field supply of DC 19-30 V with a ceiling of 1.1 A, eliminating the need for an external auxiliary supply. Encoder position data enters through a D-Sub 15 female socket, and two identical channels accept IndraDyn, HIPERFACE, 1Vss, or TTL formats so redundant feedback devices can be wired without additional interface cards.
Axis-specific analog processing is handled by the MA1 option card. It offers 2 differential ±10 V inputs for torque or speed commands and two ±10 V outputs with 12-bit resolution for feedback to legacy controllers. The encoder rails are energized at 12 V to match the requirements of incremental and absolute transducers connected on either feedback channel. Network monitoring over standard Ethernet is possible through the built-in 100Base-TX port, allowing service laptops to access diagnostic pages without disturbing the real-time fieldbus. Functional safety is integrated, and the unit supports the Safe Motion feature set so certified stop and limited-speed modes can be executed directly in the drive, reducing external wiring.
