An AC drive is an electronic device that is used to adjust the
rotating speed or torque of a standard, electric AC motor. The
electric motor, in turn, drives a load such as a fan, pump or
conveyor.
AC drives are also referred to as frequency converters,
variable frequency drives (VFD), variable speed drives (VSD),
adjustable frequency drives (AFD), adjustable speed drives
(ASD) or inverters.
ABB - global market and technology leader in AC drives
ABB (www.abb.com) is a leader in power and automation
technologies that enable utility and industry customers to
improve their performance while lowering environmental
impact. ABB is the world’s largest drives manufacturer. The
ABB Group of companies operates in around 100 countries
and employs more than 140,000 people.

ABB in North America
Our roots within North America begin with the Westinghouse
Electric Corporation, founded by George Westinghouse in 1886.
A tireless inventor and businessman, Westinghouse’s promotion
of an alternating current (AC) system revolutionized the power
industry.
Continuing to embrace the spirit of American industrialism, mining
pioneer Henry Harnischfeger joined the ABB family tree in 1981,
opening a new controls manufacturing facility in the heart of the
Midwest. Today, a cornerstone of ABB Automation Products’
business area resides within a state of the art production facility
in New Berlin, Wisconsin. The Drives and Controls operations are
responsible for the product development, applications design,
manufacture and servicing of AC and DC drives, engineered drives
and control systems, motors, generators, and power conditioning
and power quality systems.
Electric motors consume about 65% of all electricity
used throughout industry. Yet, less than 10% of those
motors are tted with a variable speed drive.
Benets of using
AC drives
Substantial energy savings
Rather than running an electric motor
continuously at full speed regardless
of the process, an electric drive allows
the user to slow down or speed up the
motor based on current demands.
Optimal process control
An electric drive enables the process
to achieve the right speed and torque
while maintaining its accuracy. This
contributes to more consistent quality
and throughput of the end product.
ABB drives common
features
Easy to select
Selecting a drive can be as simple as
choosing the power rating, voltage and
current through to more complex and
detailed dimensioning and the addition
of various options. See our guide on
page 5 to get started.
Easy to purchase
ABB drives are available from a large
network of approved ABB partners.
Please contact ABB for more details.
Reduced need for maintenance
Controlling the speed or torque of an
electric motor means there is less wear
and tear on the motor and the driven
machine.
Efficient system upgrade
An AC drive allows for the removal of
valves, gears and belts. It also ensures
network dimensioning based on a lower
starting current.
Easy to install
The drives are simple to install, featuring
a variety of mounting options from wallmounted to cabinet mounted.
Easy to operate
Once installed and commissioned, the
drives are incredibly easy to operate.
The user interface allows instant
adjustments to speed or other more
advanced parameters.

Choosing the right drive for your application
StepProcessAction
Identify the application
1
Identify the type of application and the likely demands of the drive.
Understand the load.
System inertia, required acceleration and deceleration rates, minimum and maximum speeds, overload requirements, etc.
2
This information can often be determined by the performance of the existing motor.
Gather the motor nameplate data.
3
Power, Voltage, Current, Frequency(Hz), RPM, Insulation Class, etc.
Choose a drive
Match the data gathered in Steps 1 to 3 against the table of drive features on page 6 and 7. Select a drive that meets the
4
motor requirements and has all the software features needed for the application.
Is the drive offered in the correct hp/amp rating?
The drive you choose must be able to supply the necessary current to the motor to produce the torque required. This
5
includes normal and overload conditions.
See selection table on page 6 and 7.
Is the drive offered in the correct enclosure and environmental ratings?
The drive you choose must be available in an enclosure style that will withstand the application’s environment. It also must
6
produce the required current at the application’s altitude and ambient temperature.
See selection table on page 6 and 7.
Continue to step 2.
Continue to step 3.
Continue to step 4.
Continue to step 5.
If yes, continue to
step 6.
If no, go to step 4.
If yes, continue to
step 7.
If no, go to step 4.
Does this drive have the features needed to meet the application’s demands?
The drive you choose must have a feature set that matches the application. It also must have sufficient hardware (inputs and
7
outputs, feedback, communications, etc.) to perform the application.
See selection table on page 6 and 7.
Does this drive have the motor control performance to meet the application’s demands?
The drive you choose must be able to produce the needed torque at the necessary speeds. It must also be able to control
8
speed and torque depending on the application requirements.
