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.

Note: The motor behave as generator during deceleration and the energy is regenerated to
the drive. As a result, the DC voltage in the inverter increases and cause over-voltage
trip when exceeding the OV level. When the voltage is set high, deceleration time can
be set shorter thanks to the energy consumption due to the incensement of loss in
inverter. In order to set deceleration time shorter without over-voltage trip, please try
to set AVR off during deceleration or to tune the AR filter time constant and AVR
deceleration gain.
