ABB 69068472 ACS800-38-0320-3 Low Harmonic Drive 320 A Industrial Variable Frequency Drive

The ACS800-38 is part of ABB’s low harmonic drive offering and is intended to provide a practical alternative to conventional drive configurations when the electrical network requires improved harmonic performance. The drive combines an active line-side converter with a motor-side inverter so that the motor can be controlled while the input current waveform is managed more effectively. This architecture makes the ACS800-38 suitable for industrial installations where power quality and motor control must be considered together.

ABB ACS800-38-0320-3 Drive Configuration

The ACS800-38-0320-3 is identified for three-phase supply systems in the 380 V, 400 V and 415 V range. The 0320 designation represents the drive rating class within the ACS800-38 product family. Technical documentation for the ACS800 family places the -0320-3 configuration within the R8 frame class, providing a high-power platform for industrial motor applications.

The drive is designed for demanding applications in which a conventional six-pulse frequency converter may introduce significant current harmonics into the electrical supply. By using an active line-side converter, the ACS800-38 can control the input current and support a lower-harmonic operating concept. This characteristic is particularly relevant in facilities with sensitive electrical equipment, limited transformer capacity or strict requirements for power quality.

Low Harmonic Drive Technology

Harmonic currents are generated when nonlinear electrical loads draw current from an alternating-current network. Variable frequency drives are one example of equipment that can influence the harmonic profile of an electrical installation. Excessive harmonic distortion may increase losses in transformers and cables, create additional heating and affect other equipment connected to the same electrical network.

The ABB ACS800-38 addresses this issue through its low harmonic drive architecture. Instead of relying solely on passive filtering, the drive uses an active supply-side converter to influence the shape of the input current. This provides a more integrated approach to motor control and power quality, allowing the drive to operate as part of an electrical system where harmonic performance is an important design consideration.

Motor Control and Power Conversion

The ACS800 platform is designed for variable speed control of industrial motors. The drive converts incoming electrical power into a controlled output suitable for the connected motor, allowing operating speed and torque to be adjusted according to process requirements. This capability can improve process control while allowing motor operation to be matched more closely to the actual mechanical load.

The ACS800-38-0320-3 uses a motor-side inverter to control the output supplied to the motor. Depending on the selected control configuration and application, the ACS800 family can provide advanced motor-control functions suitable for applications ranging from pumps and fans to conveyors, compressors, extruders and other industrial machinery.

The combination of controlled motor-side conversion and active line-side operation distinguishes the ACS800-38 from many conventional variable frequency drive arrangements. It allows system designers to consider motor performance and electrical network behavior as related aspects of the same drive installation.

Industrial Application Areas

ABB ACS800-38 low harmonic drives can be applied in industrial systems where motor speed control and electrical power quality are both significant. Typical application areas include pumps, fans, compressors, conveyors, material handling equipment, process machinery and other continuous-duty industrial systems.

Pumping systems can use variable speed control to adjust motor operation according to changing process demand. Fan applications can similarly benefit from controlled motor speed when airflow requirements vary. In conveyor systems, controlled acceleration, deceleration and operating speed can help coordinate material movement with the overall production process.

Compressor and process equipment applications may also benefit from variable frequency control because motor operation can be adjusted to process conditions instead of maintaining a fixed operating point. The low harmonic characteristics of the ACS800-38 become particularly relevant in installations where several large electrical loads operate from the same power distribution system.

Electrical System and Harmonic Considerations

When a high-power variable frequency drive is installed, the characteristics of the surrounding electrical network must be considered. Transformer impedance, cable arrangement, supply voltage, motor characteristics, installation environment and other loads can influence the final performance of the complete system. A low harmonic drive can reduce the contribution of the drive to supply-side harmonic distortion, but the complete electrical installation still needs to be evaluated according to the applicable engineering requirements.

The ACS800-38 architecture is therefore useful in projects where harmonic mitigation needs to be incorporated into the drive itself. This can simplify system-level planning compared with applications that require separate external harmonic mitigation equipment. The exact harmonic performance depends on the operating point and installation conditions and should be verified using the applicable ABB technical documentation.

Control and Integration in Industrial Automation

The ACS800 family was developed as an industrial drive platform rather than as a basic standalone frequency converter. Its control architecture allows the drive to form part of a larger automation system. In a production environment, drive operation may need to be coordinated with programmable logic controllers, process controllers, sensors and other automation equipment.

The ACS800-38-0320-3 can therefore be considered as a component within a complete motor control system. Engineering teams should evaluate the required control interface, motor data, acceleration and deceleration requirements, protection functions and application-specific parameters during system configuration. Correct parameterization is essential for achieving the intended motor-control characteristics.

ABB 69068472 Identification

ABB 69068472 is particularly useful when identifying the exact drive associated with this ordering reference. Industrial equipment may contain multiple identification numbers, including product model codes, ordering numbers, serial numbers and configuration references. For procurement, maintenance and replacement work, the relationship between 69068472 and ACS800-38-0320-3 provides an important identification reference.

When replacing or specifying the drive, the complete type designation should be compared with the original equipment documentation. Supply voltage, drive rating, frame size, options, control configuration and installation requirements should be checked before selecting a corresponding unit. This is especially important for ACS800 installations because different suffixes can represent different voltage classes or product configurations.
