Automatic Voltage Regulation (AVR) Function
The automatic voltage regulation (AVR) feature keeps the inverter output waveform at a
relatively constant amplitude during power input fluctuations. This can be useful if the
installation is subject to input voltage fluctuations. However, the inverter cannot boost its
motor output to a voltage higher than the power input voltage. If you enable this feature,
be sure to select the proper voltage class setting for your motor.
