It addresses common pain points like harmonic distortion, energy waste, and complex integration with legacy pumping systems. The unit ships with an IP21 enclosure by default, with IP55 and flange-mount variants available, and delivers ultra-low THDi by design, exceeding typical low-harmonic standards. This combination supports energy efficiency, reliability, and easier installation while integrating with ABB's Drive Composer tool and sensorless flow calculation features, enabling operators to optimize pump performance and reduce total cost of ownership. For engineers and procurement teams, the solution aligns with reliability requirements, maintenance predictability, and scalable control across multi-pump installations.
Product Information
Extended Description
3AXD50000429967 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.
Ultra-low harmonic performance with THDi <3% and built-in low harmonic line filter reduces electrical stress and eliminates the need for external filters, delivering smoother power quality and lower installation costs. Business impact: lower energy waste, fewer harmonics-related outages, easier compliance with harmonic standards. Application: municipal water or wastewater pumping where power quality is critical and space is limited. Sensorless flow calculation and multipump control improve process visibility and enable precise head and flow management, increasing system efficiency and reducing pump wear. Business impact: longer pump life, reduced maintenance, and lower total cost of ownership. Level control, soft pipe fill, and dry run protection safeguard equipment and ensure consistent system performance, supporting steady operations in variable demand scenarios. Application: lift stations and treatment facilities where reliability is non-negotiable. Output voltage boost and power factor correction boost motor performance, reducing current draw and improving overall plant efficiency. Business impact: energy cost savings and better electrical system balance, especially in facilities with variable-speed pumping. Usability features such as Hand-Off-Auto, Drive Composer PC tool, and optional Bluetooth control panel shorten commissioning time and enable remote diagnostics. Application: rapid deployment in new builds or retrofits, with streamlined maintenance workflows. Enclosure flexibility with IP21 by default and IP55 option provides installation versatility in compact spaces and harsher environments. Business impact: faster installation, fewer enclosure reworks, and adaptable mounting across plant layouts.

FAQs
The 3AXD50000429967 is designed for seamless integration with standard PLCs and ABB Drive Composer software. It supports sensorless flow calculation and multipump control, enabling straightforward parameter synchronization with existing control logic. During installation, verify supply voltage, motor rating, and network baud rates, then commission using Drive Composer for automated tune, peak current checks, and diagnostic logging to ensure reliable interoperability with your plant PLC.
THDi measures input current distortion; the 3AXD50000429967 targets ultra-low harmonic performance with THDi under 3%. This is achieved through an integrated low harmonic line filter and advanced control algorithms, reducing electrical stress on transformers and downstream equipment while improving overall power quality in water/wastewater applications.
Yes. The drive is designed for LV AC wall-mounted pump applications in water and wastewater systems, including surface pump installations and lift stations. Its compact form factor, integrated filter, and pump-specific features (sensorless flow, level control, dry run protection) make it suitable for new builds and retrofits where space and power quality are critical.
The unit ships with an IP21 enclosure by default, with IP55 and flange-mount variants available for enhanced protection in tougher environments. While CE compliance is typical for ABB products in Europe, this data sheet highlights IP ratings and low-harmonic performance as key compliance indicators, along with protection features like dry run and quick ramps that support regulatory and safety expectations in water facilities.
Expect reduced maintenance due to sensorless control, dry run protection, and robust pump protection features, which extend bearing life and minimize unplanned downtime. Energy savings stem from improved power factor and reduced harmonic losses. ROI improves further with simplified installation (no external filters needed) and faster commissioning via Drive Composer, enabling faster project completion and lower total cost of ownership.
