It is used to set the corresponding AUI2 voltage of the external analog input 0.

The relation between external input voltage/current and setting frequency is equal to -10~+10V (4-20mA) corresponds to 0-60Hz.

03-06	Positive/negative Bias Mode (AUI1)

03-08	Positive/negative Bias Mode (AUI2)
Control	VF	VFPG	SVC	FOCPG TQCPG FOCPM	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 operating frequency.
