AVR: auto voltage adjustment. This function can keep constant output
voltage when the input voltage deviates from rated value. Therefore, the
function should be enabled all the time especially when the input voltage
is higher than the rated value.
If AVR is disabled during deceleration, the Dec time is shorter but the
current is higher, otherwise, the motor decelerates smoothly with lower
current, but the Dec time is longer.
