Leading the way in HVAC drives
Comfort. It’s something we take for granted in the buildings we live and work in. But comfort requires efficient systems to control heating, ventilation, and air conditioning (HVAC) to ensure the air we breathe is pure and the temperature is comfortable. We also need to ensure air quality and safety in the most energy-efficient and cost-effective way in both normal and mission-critical situations.
For half a century, ABB has been leading the way in optimizing HVAC systems using drive control to ensure that you can take comfort for granted. The new ACH580 series of variable-frequency drives (VFDs) provide the quality, reliability, and energy savings you expect, and are easy to use and safe to maintain. All you need to do is to set the drive up, and then focus on what counts.
The next step in HVAC drives
The new ACH580 drives come with a range of advanced features, such as a new primary settings menu that makes commissioning the drives much easier and faster. Bluetooth connectivity offers improved accessibility for drives in remote areas and increases safety by letting users stay out of arc flash zones.
Simple to select, install and use
All the essentials – such as chokes, EMC filters, cabling clamps, certified BACnet communication, and enclosures from IP21/UL (NEMA) Type 1 to IP55/UL (NEMA) Type 12 – are a standard part of the drive, simplifying selection, installation, and commissioning.
The new packaged disconnect solution provides a main disconnect switch, further increasing safety for people working on air-handling units.
Motor control options to meet your application needs
ACH580 drives can be integrated with several types of AC motors, even high-efficiency permanent magnet (PM) and synchronous reluctance (SynRM) motors. Using these motors can reduce your energy costs even more.
Additional I/O options
Take advantage of the added flexibility and accessibility – never be without back-up I/O points at the job site again.
ACH580 drives are ideal for the HVAC fans, pumps, compressors,
air-handling units, and chillers used in hospitals, data centers, shopping
centers, tunnel ventilation, factories, office buildings, and more.
Intuitive control panel
The drive’s HVAC-specific software, intuitive keypad with customizable text, and menu-driven programming simplify setup and operation of even the most complex applications. You can customize the view so that it only shows the information you need, and it automatically saves a backup of your most recent configuration so that it’s always available.
Optional Bluetooth® capability
The drive provides reduced harmonics with built-in, second-generation swinging
choke technology in a small and lightweight design.
Optional ultra-low harmonics (ULH) for a clean network
Premier air handling
We understand the complexity of air handling systems and the need to produce high levels of comfort, control, and safety. Regardless of the season or external conditions, we help make your system efficient, safe, and informative.
Effortless system startup
The ACH580 ensures a smooth, coordinated start to your HVAC system. Embedded interlock logic enables the drive to confirm that equipment such as dampers are in the right position and sensors are showing the correct status before operations begin. The Drive Composer PC tool simplifies the use of the drive, and the control panel’s primary settings menu and built-in assistants speed up commissioning, allowing basic setup to be completed in minutes.
Increased energy savings
Achieve increased energy savings by using the appropriate motor and drive combination. The ACH580 drive works with induction, PM, or SynRM motors, enabling high efficiencies.
Built-in safety functionality, such as override mode, enables your system to ignore all non-essential faults during emergencies to maintain air quality in the fire exit paths.
The keypad’s optional Bluetooth capability provides an extra level of safety for commissioning and troubleshooting.
The ACH580 reduces costs, for example by eliminating dependencies on external controllers. The drive can use its internal PID loops to maintain a pressure setpoint by checking the active pressure and adjusting the fan speed accordingly
Improved monitoring and maintenance
Leverage advanced system monitoring, giving you access to data on all aspects of the operation. Use this information to plan maintenance based on the actual needs of the application. For example, with built-in monitoring, the drive lets you know when it’s time to take action if a fan stalls, a belt breaks, a filter clogs, and more.
Precise water flow control
Controlling the flow of chilled water in HVAC systems allows you to regulate temperatures in a building. Pumps, chillers, and cooling towers all need to be coordinated. Your system benefits from motor control that operates as efficiently and simply as possible, with functions designed to keep the flow rate in line with the needs of the chiller and the building.
Motor monitoring prevents problems
Protect your investment with onboard monitoring. Monitor and show trends of key attributes for preventative maintenance.
Protect your equipment
Extend the life of your equipment (e. g. pipes, motors, check valves, and pumps) with intelligent motor control. By starting the pumping system smoothly, you protect the system from pressure surges, and can precisely manage the flow and the pressure.
Energy savings through intelligent control
Intelligent motor control replaces throttle or bypass valves, enabling better control of flow, and resulting in energy savings. In addition, fewer mechanical parts means minimal wear and tear on the system. For additional savings, pair drives with premium-efficiency motors and enable energy optimizer functions to reduce operating costs over the lifetime of the pumping system.
As demand fluctuates during the day, the system automatically adjusts. The ACH580 provides optimal pressure when needed, and goes into sleep mode when it’s not. For example, if the chiller shuts off as demand varies throughout the day, the pump can go into standby

Overcome challenges of harmonics
ACH580 ultra-low harmonic drives have excellent harmonics performance and are perfectly suited for places that cannot handle high harmonic content in the network.
The problem with harmonics
Generators in power plants rotate at constant and regulated speed, resulting in a sine-waveshaped current in an AC grid in the ideal case.
However, in the modern world, the network is not pure sine wave. Electricity networks are affected by harmonics: higher-order oscillations introduced by various types of electrical equipment.
Harmonics in the electrical system can have negative effects, such as overheating or malfunctioning network components, including transformers or other equipment in the same grid. Even with 40% THDi, there is still approximately 35 percent over-dimensioning needed for the transformer.
All-in-one concept for a clean network
ABBʼs HVAC ultra-low harmonic (ULH) drives are designed with built-in harmonic avoidance systems and help your system to meet IEEE519 and G5/4 harmonic recommendations. By equipping the drives with specific features and capabilities, the problems caused by harmonics are avoided in the first place.
There is no need for external harmonic filters or multi-pulse transformers, leading to significant savings in the footprint. Compared to other harmonic mitigation solutions, ULH drives have excellent harmonic performance, ensuring that the current harmonics in undistorted networks and at nominal load are below 3 percent.
ULH drive technology
With an integrated design that leverages drive technology as part of the harmonic solution, there is no risk of nuisance trips due to incompatible components, no need for additional hardware, and no additional cooling requirements.
Lower energy consumption at system level
ABBʼs HVAC ULH drives reach a unity power factor, indicating that electrical energy is being used efficiently. Active power factor compensation allows the ULH drive to improve the power factor of the building grid, while maintaining the unity power factor on the connected equipment.
Reliable operation under special conditions
ULH drives ensure that the motor receives the full voltage, even in low-voltage utility conditions. Thanks to the drives’ capability to provide an output voltage up to 15 percent greater than the supply voltage, applications can overcome voltage drops caused by long supply or motor cables. All this is done without costly additional equipment or oversizing of drive system components.
Other ways of mitigating harmonics
Passive filter equipment must always be sized for the maximum current, but the duration of partial-load operation is very significant. Oversizing gives poor mitigation performance and high running costs when running at partial load. It is also a waste of money, as it does not mitigate harmonics properly under partial-load conditions.
With multipulse transformers, you always need to install additional transformers, and the mitigation level isn’t at the same low level as in a ULH drive.
Of course, needs for mitigation vary and there is no one-size-fits-all solution.
