1.4 Product Overview
1.4.1 Intended Use
The adjustable frequency drive is an electronic motor
controller intended for:
•The regulation of motor speed in response to
system feedback or to remote commands from
external controllers. A power drive system
consists of the adjustable frequency drive, the
motor and equipment driven by the motor.
•System and motor status surveillance.
The adjustable frequency drive can also be used for motor
protection.
Depending on conguration, the adjustable frequency
drive can be used in standalone applications or form part
of a larger appliance or installation.
The adjustable frequency drive is allowed for use in
residential, industrial and commercial environments in
accordance with local laws and standards.
NOTICE!
In a residential environment, this product can cause
radio interference, in which case supplementary
mitigation measures can be required.
Foreseeable misuse
Do not use the adjustable frequency drive in applications
which are non-compliant with specied operating
conditions and environments. Ensure compliance with the
conditions specied in chapter 8 Specications.
