A frequency converter is an electronic motor controller that converts AC mains input into
DC and then into a variable voltage, variable frequency output waveform. The following is
a list of functions of the frequency converter:
• Regulates the frequency and voltage to control the motor speed or torque.
• Varies the speed of the motor in response to system feedback, such as changing
temperature or pressure for controlling fan, compressor, or pump motors.
• Regulates the motor by responding to remote commands from external controls.
• Monitors the system and motor status.
• Issues warnings or alarms for fault conditions.
• Starts and stops the motor.
• Optimizes energy efficiency.
Operation and monitoring functions are available as status indications to an outside
control system or serial communication network.
