Product Information
Extended Description
3AXD50000332069 ABB: The ACQ580-31 drives deliver innovative pump features for the water and wastewater industry, securing energy efficient flow of water and wastewater in your pumping solutions. The ultra-low harmonic variant provides ultimate harmonic performance, reaching even less than 3 % THDi, and exceeding the requirements set by low harmonic standards and recommendations. The drive includes an active supply unit and integrated low harmonic line filter, meaning there is no need for external filters, multi-pulse arrangements or special transformers.
Other features include output voltage boost and power factor correction. This robust and compact wall-mounted drive has built-in pump application functionality such as sensorless flow calculation, multipump control, level control, soft pipe fill, dry run protection, quick ramps and a solution for keeping the impeller of the pump clean. Usability is further enhanced with the intuitive Hand-Off-Auto control panel, the PC tool Drive composer and an optional Bluetooth=C2=AE control panel. The ultra-low harmonic wall-mounted variant comes in IP21 enclosure as standard. Also, IP55 and flange mounting units are available.
The ultra-low harmonic variant reduces THDi to less than 3%, delivering cleaner power and reducing the need for external harmonic mitigation—a direct business impact that lowers installation and operating costs for water and wastewater pumping. This drives energy efficiency gains and helps meet regulatory expectations while simplifying compliance checks during plant audits. The built-in active supply unit and integrated low harmonic line filter eliminate external filters or complex multi-pulse arrangements, enabling a compact, space-saving wall-mounted installation suitable for retrofit projects or new builds. Output voltage boost and power factor correction improve motor performance and overall energy intensity, translating to measurable savings on kilowatt-hour consumption in long-run pumping cycles and in high-demand hours. Pump-specific features—sensorless flow calculation, multipump control, level control, soft pipe fill, and dry run protection—enhance reliability, reduce wear, and minimize unplanned downtime in process-critical water networks. Quick ramps and impeller cleaning support smooth startup and continuous operation, while the Hand-Off-Auto control panel, Drive Composer PC tool, and optional Bluetooth panel accelerate commissioning, diagnostics, and remote supervision. The enclosure options, IP21 standard with IP55 as an upgrade, provide flexible installation in plant rooms or outdoor enclosures, improving maintenance access and protection against contaminants. Overall, the ABB drive combines robust hardware with a user-centric interface to lower total cost of ownership in water and wastewater pumping applications.

FAQs
Installation starts with selecting the IP21 enclosure base and confirming the 400 V (IEC) or 480 V (UL) input options. Mount the drive on a stable wall surface, connect the control and power cables per the wiring diagram, and enable the Hand-Off-Auto mode for safe commissioning. Take advantage of the integrated low harmonic filter to minimize external components, and use Drive Composer for alignment with your SCADA and safety interlocks.
The ultra-low harmonic variant delivers THDi below 3%, reducing electrical stress on upstream transformers and downstream equipment. This improves power quality, lowers energy losses, and minimizes the need for external harmonic mitigation measures. In water and wastewater pumping, the result is more predictable motor performance, extended pump life, and easier compliance with harmonic limits in sensitive networks.
Yes. The drive supports multipump control and level sensing features, enabling coordinated operation across several pumps and staged starts to balance demand. Sensorless flow calculation helps optimize pump speed without additional sensors, while dry-run protection reduces equipment damage during startup delays or flow interruptions. This translates to reduced maintenance costs and improved system reliability.
The drive includes UL-listed configurations for North American compliance and ships with an IP21 enclosure as standard, with IP55 options available for more demanding environments. These certifications and ratings help ensure safer operation in plant rooms and outdoor installations, while supporting industry-standard safety and performance requirements in water utilities.
By eliminating external harmonic filters, simplifying installation, and enabling quick commissioning through Drive Composer and optional Bluetooth control, the drive reduces first-install time and ongoing maintenance. Integrated pump-specific features minimize wear and downtime, while energy efficiency improvements lower operating costs over the life of the system, delivering a compelling ROI for municipal and industrial water applications.
