0: No operation

1: The inverter restores all default parameters.

2: The inverter clears latest alarm records.

Note: after finishing this operation, the value of the function code will return to 0

automatically. Restore defaults will not reset 01-01~01-11 parameters.

AVR function equals to the output voltage auto-adjustment function. When AVR function is

unavailable, the output voltage varies with input voltage (or DC bus voltage). When AVR

function is available, the output voltage will not vary with input voltage (or DC bus voltage)

and keep basically constant output voltage within its range.

Note: When the motor is in decelerates stop, the motor will stabilize voltage

automatically and close AVR function to stop in shorter deceleration time without

over voltage.
