Product Information
Extended Description
3AXD50000234851 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.
Integrated low harmonic line filter eliminates external filtering hardware, reducing installation footprint and field wiring while delivering compliant power quality. Feature → Business Impact → Application: Quiet operation and minimal harmonic distortion lower electrical losses and improve pump reliability, particularly in long-run water and wastewater pipelines. The ultra-low THDi < 3% enables compliant operation in networks with sensitive equipment, reducing interference with upstream systems and enabling simpler protective coordination in municipal plants. Sensorless flow calculation, multipump control, and level management empower advanced pump sequencing, reducing energy use and enabling more precise water treatment workflows in multi-pump stations. Built-in dry run protection and soft ramp functionality protect pumps from damage during startup, improving maintenance intervals and extending service life. The Hand‑Off‑Auto panel and Drive Composer PC tool simplify commissioning and remote diagnostics, while the optional Bluetooth control panel supports on-site adjustments without retraining staff. IP21 enclosure provides standard protection, with IP55 and flange mounting available for tougher environments or retrofit projects.

FAQs
Installation guidance starts with confirming supply is compatible with 400 V input and the motor rating of 4 kW. Mount the unit on a suitable wall, connect the integrated line filter, and link to the pump sensors. Use Drive Composer for configuration, enable Hand-Off-Auto control, and verify dry-run protection and soft-start ramps to prevent pump damage during commissioning.
A THDi below 3% significantly reduces harmonic distortion, improving power quality for pumps and upstream equipment. This translates to lower heating losses, reduced EMI, and potential savings on filter capacity. You gain more stable voltage supply to motors, better control of flow during variable-speed operation, and improved compliance with harmonic guidelines in municipal networks.
Yes. The ACQ580 supports multipump control and level control features, enabling coordinated operation of multiple pumps. Sensorless flow calculation helps optimize pump sequencing, while dry run protection guards against dry-running scenarios. This results in energy savings, reduced wear, and more reliable maintenance scheduling in complex pumping stations.
The standard enclosure is IP21, suitable for indoor installations, with optional IP55 and flange mounting variants for harsher environments or retrofit projects. The drive includes an integrated line filter and built‑in protections like dry run and soft ramping, enhancing pump safety and reducing external hardware needs in regulated water facilities.
Expect reduced energy consumption due to optimized pump control, fewer external filters, and simpler wiring thanks to the integrated line filter. The built-in features shorten commissioning time, decrease maintenance complexity, and extend pump life through soft ramps and dry-run protection. Overall, this drives faster payback in water and wastewater facilities through energy savings and reduced capital spend on ancillary equipment.
