Product Description

The NDCU-12K (Network Drive Control Unit) is an integrated assembly that typically combines the NIOC-01 I/O and Control board with a powerful processor. It is responsible for executing the drive software, processing analog and digital I/O, and facilitating communication between the drive and external PLC systems or fieldbus networks. It is engineered to provide precise torque and speed control for AC motors.

Product Parameters

The technical specifications define its capability to handle complex motor control tasks:

• Model Number: NDCU-12K

• Compatibility: Exclusively for ABB ACS800 series high-power drives.

• Supply Voltage: Powered internally via the drive’s power supply board (typically 24V DC).

• Processor Type: High-speed digital signal processor (DSP).

• Control Interface: Supports fiber optic links for communication with power modules (Inverter Units).

• I/O Capability: Includes multiple digital inputs/outputs and analog inputs/outputs via the integrated board.

• Memory: Flash memory for firmware and parameter storage.

Product Advantages

• Advanced Direct Torque Control (DTC): Enables extremely fast and accurate motor control without the need for pulse encoders in many applications.

• Modular Design: Its compact and pluggable design allows for easy maintenance and hardware upgrades within the ACS800 ecosystem.

• High Reliability: Built to withstand the electrical noise and thermal demands of heavy industrial environments.

• Extensive Connectivity: Supports a wide range of fieldbus adapters (such as PROFIBUS, Modbus, or ControlNet) through dedicated slots.

Important Considerations

• Firmware Loading: When replacing an NDCU-12K, the correct firmware and application software must be downloaded to the unit before it can control the motor.

• Electrostatic Discharge (ESD): As a sensitive electronic control board, it must be handled using proper ESD protection to prevent permanent internal damage.

• Fiber Optic Handling: The fiber optic connectors are fragile; ensure they are clean and not bent beyond their minimum radius during installation.

• Parameter Backup: Always backup the drive parameters before replacing the control unit to ensure the new unit can be configured identically.

Product Applications

The NDCU-12K is found in heavy-duty applications where the ACS800 drive is utilized:

• Metals and Mining: Controlling large conveyor belts, crushers, and mill drives.

• Pulp and Paper: Managing the precise speed synchronization of rollers in paper machines.

• Oil and Gas: Driving high-capacity pumps, compressors, and fans.

• Marine: Used in propulsion systems and thruster controls for large vessels.
