2.2 Product Overview
A frequency converter is an electronic motor controller
that converts AC mains input into a variable AC waveform
output. The frequency and voltage of the output are
regulated to control the motor speed or torque. The
frequency converter 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 frequency converter can also regulate
the motor by responding to remote commands from
external controllers.
In addition, the frequency converter 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.
