Product Information
Extended Description
3AXD50000429981 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 is achieved with an integrated low harmonic filter, delivering THDi under 3% and reducing the need for external filters or multi-pulse arrangements. Business impact: simplified installation, lower BOM, and improved power quality for water and wastewater pumps. Application: retrofits and new builds where compliance with low-harmonic standards is essential. Sensorless flow calculation, multipump control, level control, and dry-run protection enable precise process control, prevent pump damage, and reduce energy waste in variable demand scenarios. Business impact: extended pump life, reduced downtime, and energy savings across duty cycles. Output voltage boost and power factor correction enhance motor performance and grid efficiency, lowering electrical stress and improving overall plant efficiency. Application: large-scale pumping stations and treatment facilities seeking reliable operation with fewer control components. The Hand-Off-Auto control panel, Drive Composer PC tool, and optional Bluetooth control panel streamline commissioning, diagnostics, and remote maintenance. Business impact: faster deployment, easier troubleshooting, and lower on-site labor costs. IP21 enclosure is standard for typical indoor installations, with IP55 and flange-mount options available for harsher environments. These installation advantages translate to flexible siting and reduced enclosure penalties. Additional integrated features, including an active supply unit and built-in low harmonic line filter, simplify system integration and compliance with harmonic standards, reducing overall project risk and lifecycle cost.

FAQs
The 3AXD50000429981 is a low-harmonic, wall-mounted drive designed for LV motors in water and wastewater applications. It supports typical LV motor sizes used in pumps and can be installed on walls with the standard IP21 enclosure; IP55 is available for harsher environments. Use Drive Composer for commissioning and verify motor rating compatibility with the drive’s output range. No external low-harmonic filters are required thanks to the built-in filter.
This drive delivers ultra-low harmonic performance with THDi under 3%, thanks to an integrated low harmonic filter. This substantially reduces harmonic distortion without external filters, aiding compliance with utility standards and enabling simpler electrical design. It also decreases EMI concerns and can improve power quality metrics across the plant’s drive trains.
Yes, the drive is designed for water and wastewater pumping. Features such as sensorless flow calculation, multipump control, level control, and dry-run protection support reliable operation in variable demand conditions. Quick ramps and soft pipe fill reduce water hammer, while an integrated controller simplifies multi-pump configurations and safeguard routines, improving uptime and process stability.
The drive ships with a standard IP21 enclosure and offers IP55 as an option, enabling installation in more demanding environments. While the data does not specify CE or SIL ratings, ABB drives typically align with regional electrical standards. For projects with strict certification needs, confirm local compliance requirements with ABB or your distributor prior to procurement.
Expect reduced maintenance through features like dry-run protection and sensorless control that minimize pump wear and fault events. Energy savings arise from improved power factor, voltage boosting, and efficient motor operation under varying loads, plus a simplified install that lowers initial capital cost. Long-term ROI improves with reduced downtime, fewer external filters, and streamlined diagnostics via Drive Composer and optional Bluetooth monitoring.
