E ffortless energy efficiency is the best way to describe the new ACS580, ABB’s new all-compatible general purpose drive.Through drive selection, set up, operation andmaintenance, theACS580 simpli- fies control processes efficiently. “The drive is virtually plug-in-ready to control pumps, fans, conveyors, mixers and many other variable and basic constant-torque applications, while requiring very little time for set up and commissioning”, says Riaan van Jaarsveld, Vari- able Speed Drives Sales Manager for South Africa. “Furthermore all essential features are built-in, making drive selection and use easy, and giving users better management and savings of precious energy”. The ACS580 power range is 0,75 to 250 kW and voltage range is 208 to 480 V. A wall-mounted drive is available with IP21 enclosure or IP55 enclosure optional. The drive becomes an energy-saving tool The drive controls the process more energy efficiently based on actual need, rather than fixed-speed and mechanical flow control often used in applications like pumps and fans. An energy optimiser feature ensures maximum torque per ampere and reducing energy drawn from the supply. The kWh counters monitor hourly, daily and cumulative energy consumption of the drive.The energy saving cal- culators show savings for energy, CO 2 emissions and money when the drive replaces other control methods.

All features built-in All the essential features are built into the drive as standard, reducing the need to deal with external components, extra cabling and space restrictions. The drive provides reduced harmonicswith built-in second- generation swinging choke technology in a smaller and lighter design. Other built-in features include EMC filter, brake chopper up to frame R3, Modbus RTU fieldbus interface and safe torque off. The drive’s capability can be extended with optional plug-in modules. A wide range of fieldbus adapters can easily be mounted inside the drive al- lowing connectivity to all the major industrial fieldbus protocols.The standard I/O can be extended by using optional analogue and digital extension modules. Standard software with versatile features The drive’s advanced software improves process control. A built-in, stand-alone process PID controller makes the ACS580 a self-governing unit requiring only an external process measurement. For pumping applications the sleepmodemomentarily elevates levels or pressures, thus extending the sleepmode to save energy.The flying start catches a runningmotor with long freewheeling times, as in fan applications.The drive reducesmotor noise by spreading the switching frequencies over a user-specified range.The higher used switching frequency reduces motor noise at low load without limiting full current at maximum load. All-compatible drives architecture for scalability with- out adding complexity The ACS580 general purpose drives are part of ABB’s all-compatible drives portfolio, offering customers scalability without adding com- plexity. The ABB all-compatible drives share the same user interfaces and options, meaning once a user has experienced one all-compatible drive, they will be able to quickly adopt and use others.

Easy and intuitive user interfaces The control panel and PC tool simplify the use of the drive. The control panel’s settings menu and built-in assistants speed up commissioning. Each menu is clearly named by function, such as motor, ramp and limit set- tings. The basic set up is done in minutes. The I/O menu shows how the electrical terminals are configured, and gives quick ac- cess to related terminal settings like filtering, scaling, delay or function selections.
