- Cnes Capombiability of AC/DC Power Conversion with Redundant Power Support
- Operates in Conjunction with ABB Variable Frequency Drives and Automation Control Modules
The ABB NDCU-11CK 64053868B operates as a central drive control unit within ABB motor drive and automation systems, providing reliable control logic and signal processing to all connected drive modules. It continuously interprets incoming commands, executes vector‑based motor control algorithms, and distributes control signals to associated I/O modules to support precise speed, torque, and position regulation. Seamless integration with connected drive components is standard with the NDCU‑11CK; however, using optional redundant control or auxiliary monitoring configurations allows continuous operation in the event of a primary module fault. The NDCU-11CK 64053868B has made improvements in several areas over previous NDCU designs, including enhanced signal interfacing, industrial connectivity, and robust operation under harsh environmental conditions.
The ABB NDCU-11CK 64053868B provides essential control and signal-processing functions for the connected drive modules, and is a critical component of the motor control path, directly affecting the precise and reliable operation of the overall drive system. One NDCU‑11CK control unit is required per drive cabinet, with additional units used when redundant or auxiliary control configurations are implemented. The NDCU‑11CK occupies a compact slot within the drive cabinet and is typically positioned according to the manufacturer's recommended layout for optimal connectivity and accessibility.
For dual redundant control applications, the ABB drive system can utilize a second NDCU-11CK 64053868B installed in a redundant slot. In addition to standard single‑unit operation, the redundant configuration also performs automatic control switchover. The dual NDCU configuration executes failover using the internal logic and monitoring circuits built into the control units. Using this method, the redundant control system continually monitors the status and health of both units. If the system detects that the primary NDCU‑11CK is no longer providing stable control outputs (outside configured voltage, current, or command tolerances), it will automatically transfer control to the secondary unit and log an event in the system's control record for troubleshooting and maintenance purposes.
The NDCU-11CK 64053868B ABB Drive Control Unit may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
