This solution is UL-listed with motor overload protection and CE compliant, helping meet essential safety and performance standards across global projects. With built-in pump features, intuitive Hand-Off-Auto operation, and optional Bluetooth control, it enables engineers to reduce energy use, simplify maintenance, and accelerate commissioning in demanding plant environments. Its compact wall-mount design fits tight spaces and reduces installation costs, while sensorless control and multi-pump coordination improve reliability and extend equipment life.
Product Information
Extended Description
3AXD50000705948 ABB: The ACQ580-PC drives deliver the ACQ580 Product Series features delivering innovative pump features for the water and wastewater industry, securing energy-efficient flow of water and wastewater in your pumping solutions. This robust and compact wall-mounted packaged drive has built-in pump application functionality such as sensorless flow calculation, multi-pump 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, an optional Bluetooth=C2=AE control panel, and a UL-approved electronic motor overload. The built-in energy calculator visualizes the energy savings achieved with the use of the drive.
Integrated sensorless flow calculation optimizes pump control, reducing energy consumption and peak current while maintaining desired flow in water and wastewater systems. This directly lowers operating costs and extends motor life by minimizing thermal stress and start/stop cycles. Multi-pump control enables synchronized operation of several pumps, preventing surge, ensuring consistent head, and improving system uptime in treatment facilities and distribution networks. Dry run protection guards pumps from dry operation, reducing equipment wear and unexpected outages, which translates to lower maintenance spend and fewer repair visits. Soft pipe fill and quick ramps curb water hammer and mechanical stress during startup, safeguarding piping and valves and shortening commissioning time. The Hand-Off-Auto control panel, Drive Composer PC tool, and optional Bluetooth control panel streamline setup, parameter tuning, and remote diagnostics, accelerating project timelines and reducing on-site labor. An integrated energy calculator provides visibility into energy savings, supporting ROI justification and ongoing optimization.

FAQs
When installing the 3AXD50000705948, plan for a wall-mounted enclosure with proper ventilation and sufficient clearance for wiring and cooling. Ensure UL-listed motor overload protection is wired to the motor starter circuit, and configure the Hand-Off-Auto panel for local control. Use Drive Composer PC for commissioning and verify motor ratings align with 575 V supply and your pump load. Consider surge protection and proper grounding to minimize electrical noise affecting sensorless control.
Sensorless flow calculation estimates pump flow from drive voltage and motor parameters, enabling precise speed modulation without external flow meters. Multi-pump control coordinates several pumps to match demand, preventing head fluctuations and reducing wear from cycling. In practice, this means smoother operation, energy savings, and extended pump life in facilities with variable demand such as wastewater plants and pressure districts.
Yes. The drive is UL-listed for motor overload protection, and the product line is CE compliant, aligning with essential safety, performance, and electrical standards for industrial automation. This combination supports regulatory requirements in many regions, simplifies procurement for global projects, and reduces risk during audits and commissioning.
ROI is driven by energy savings from optimized pump speed, reduced startup current, and longer pump life due to dry run protection and smoother control. The built-in energy calculator helps quantify annual electricity reductions, while protection features minimize downtime and maintenance costs. In typical water/wastewater installations, expect faster payback when multiple pumps operate under variable demand with accurate control.
Retrofits are feasible when the existing system uses compatible 575 V motors and matches the drive’s mounting and protection requirements. Essential steps include validating motor/load compatibility, wiring to UL-rated protective devices, and updating the control scheme to the Hand-Off-Auto interface. Accessories to consider are the optional Bluetooth control panel and the Drive Composer PC tool for seamless commissioning and diagnostics.
