Chapter 4 Parameters
4-96
3 The absolute value of the bias voltage while serving as the center
4 Serve bias as the center
In a noisy environment, it is advantageous to use negative bias to provide a noise
margin. It is recommended NOT to use less than 1V to set the operation frequency.

1 AVI 2
There are two AVI analog inputs can be used when this parameter is set to 1 and the
SW2 on the control board is set to AVI2. At this moment, ACI is for voltage input.
