Beyond compliance, the solution delivers measurable business value through integrated low harmonic filtering, sensorless flow control, and easy commissioning via Drive Composer.
Product Information
Extended Description
3AXD50000429936 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.
Feature is ultra-low harmonic performance with integrated low harmonic line filter, providing THDi levels below 3 percent. Business impact is significant: improved power quality reduces electrical stress on feeders and downstream equipment, enabling smaller upstream filter requirements and smoother operation of pumps. Application: water and wastewater pumping stations that demand reliable harmonic control and simplified installation. Feature is built-in active supply unit and absence of external filters, multi-pulse arrangements or transformers. Business impact is lower installation costs, reduced space, and fewer components to maintain. Application: compact pump rooms and retrofit projects where space and maintenance budgets are tight. Feature is output voltage boost and power factor correction. Business impact: higher efficiency, better grid support, and improved pump performance under variable load. Application: municipal and industrial pumping where voltage dips are a concern. Feature is pump-aware functions including sensorless flow calculation, multipump control, level control, soft pipe fill, and dry run protection. Business impact: optimized flow, reduced risk of dry running, and improved process stability. Application: multi-pump systems and level-controlled pumping in treatment facilities. Feature is intuitive Hand-Off-Auto control panel, Drive Composer PC tool, and optional Bluetooth control panel. Business impact: faster commissioning, easier field programming, and remote diagnostics. Application: field service and remote plants requiring quick setup and ongoing tuning. Feature is compact, wall-mounted design with IP21 standard enclosure and IP55 option. Business impact: flexible installation in restricted spaces and harsh environments. Application: plant rooms, outdoor or damp environments where rugged packaging matters.

FAQs
The drive is designed for LVAC wall-mounted installations with an integrated low harmonic filter, eliminating the need for external filters. It supports sensorless flow calculation, multipump control, and level control, making it compatible with common municipal pumping architectures and retrofit projects.
THDi below 3% means significantly reduced harmonic distortion, leading to cleaner power delivery, less heat, and longer life for motors and feeders. This translates to lower maintenance costs, improved energy efficiency, and better compliance with electrical standards in pump applications.
Yes. The drive includes multipump control and level control functions, plus sensorless flow calculation, enabling coordinated operation of several pumps, reduced cycling, and improved process stability in wastewater lift stations and distribution networks.
Standard IP21 enclosure is provided, with IP55 and flange mounting variants available to suit harsher environments and different installation constraints, enabling flexible placement in plant rooms or outdoor areas.
Benefit comes from eliminating external harmonic filters, simplifying installation, reducing maintenance, and achieving energy savings through improved power factor and controlled pump operation, which collectively shorten payback in new builds or retrofit projects.
