This parameter determines the function of Automatic Voltage Regulation is enabled or disabled.
This parameter is set to 01: when AVR function is disabled, AC drive will calculate input voltage by DC Bus value (620VDC). Output voltage will vary by DC Bus varying and may cause output current insufficiently, over current or oscillation.
This parameter is set to 00: when AVR function is enabled, AC drive will calculate output voltage by actual voltage value of DC Bus. Output voltage won’t vary by DC Bus varying.
This parameter is set to 02: AC drive will disable AVR function during decelerate to stop. It can speed up braking in some degree.

This parameter determines software setting of the braking level.
The model VFD055~150F43A has braking chip, user could select suitable braking resistor to have the best deceleration characteristics.
The action level of the braking resistor could be set by this parameter.
