Product Information
Extended Description
3AXD50000428960 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.

FAQs
This drive is designed for 480 V supply and 44 A applications with a 30 HP rating. It comes in an IP21 enclosure as standard and can be upgraded to IP55 or flange-mounted configurations. Plan for proper ventilation and vibration isolation, as well as correct wiring of the integrated line filter and control wiring to the Hand-Off-Auto panel or Drive Composer tool for straightforward commissioning.
A THDi below 3% significantly reduces harmonic distortion on the electrical network, improving power quality, reducing overheating and wear on pumps and transformers, and potentially lowering energy costs. The integrated low harmonic line filter eliminates the need for external filters or multi-pulse arrangements, simplifying installation and maintenance.
Yes. The drive supports built-in pump application functionality such as multipump control, sensorless flow calculation, and level control, enabling coordinated operation of multiple pumps. This reduces peak demand, improves process reliability, and simplifies control logic for complex pumping schemes in water and wastewater facilities.
The drive is UL-listed for safety and ships with an IP21 enclosure as standard, with IP55 and flange-mount options available. It is designed to meet low-harmonic standards and is compatible with ABB’s Drive Composer PC tool for configuration and monitoring, supporting reliable field deployments in wet environments.
Benefits include energy savings from improved efficiency and reduced motor losses, lower maintenance due to integrated line filtering and protective features like dry run protection, and faster commissioning via intuitive interfaces and software. The result is shorter project timelines, fewer external components, and predictable operating costs in water and wastewater pumping systems.
