Instruction Manual

1.3 Product Overview

An adjustable frequency drive is an electronic motor
controller that converts AC line power input into a variable
AC waveform output. The frequency and voltage of the
output are regulated to control the motor speed or torque.
The adjustable frequency drive can vary the speed of the
motor in response to system feedback, such as changing
temperature or pressure for controlling fan, compressor, or
pump motors. The adjustable frequency drive can also
regulate the motor by responding to remote commands
from external controllers.
In addition, the adjustable frequency drive monitors the
system and motor status, issues warnings or alarms for
fault conditions, starts and stops the motor, optimizes
energy efficiency, and offers many more control,
monitoring, and efficiency functions. Operation and
monitoring functions are available as status indications to
an outside control system or serial communication
network.
For single phase adjustable frequency drives (S2 and S4)
installed in the EU, the following applies:
Single phase adjustable frequency drives (S2 and S4) with
an input current less than 16 A and an input of more than
1 kW are intended for use as professional equipment in
trades, professions, or industries. Designated application
areas are:
They are not intended for general public use or use in
residential areas. All other single phase adjustable
frequency drives are only intended for use in private low-
voltage systems interfacing with public supply only at a
medium or high voltage level. Operators of private systems
must ensure that the EMC environment complies with IEC
610000-3-6 and/or the contractual agreements.
