Control
mode
VF VFPG SVC FOCPG TQRPG
Factory setting: 0
Settings 0 Zero bias
1 Lower than bias=bias
2 Greater than bias=bias
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.
