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 has an erratic power source. 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.
