Analog Input Bias 1 (AUI1)
Control Mode VF VFPG SVC FOCPG FOCPM Default: 0.0
Settings -100.0–100.0%
 Sets the corresponding AUI1 voltage for the external analog input 0.
Reserved

Analog Input Bias 1 (AUI2)
Control Mode VF VFPG SVC FOCPG FOCPM Default:0.0
Settings -100.0–100.0%
 Sets the corresponding AUI2 voltage for the external analog input 0.
 The relation between external input voltage/current and setting frequency is equal to -10–10 V (4–20 mA)
corresponding to 0–60 Hz.

AUI1 Positive/negative Bias Mode
Control Mode VF VFPG SVC FOCPG FOCPM Default: 0

AUI2 Positive/negative Bias Mode
Control Mode VF VFPG SVC FOCPG FOCPM Default: 0
Settings 0: Zero bias
1: Lower than or equal to bias
2: Higher than or equal to bias
3: Use bias as the base to get the absolute value of bias voltage (unipolar)
4: Using bias as the base (unipolar)
 In a noisy environment, you can use a negative bias to provide a noise margin. It is recommended that
you NOT use less than 1 V to set the operating frequency.
