Analog Input Bias (ACI)
Factory Setting: 0
Settings -100.0~100.0%
It is used to set the corresponding ACI voltage of the external analog input 0.
Analog Voltage Input Bias (AUI)
Factory Setting: 0
Settings -100.0~100.0%
It is used to set the corresponding AUI voltage of the external analog input 0.
The relation between external input voltage/current and setting frequency: 0~10V (4-20mA)
corresponds to 0-60Hz.

Positive/negative Bias Mode (AVI)
Positive/negative Bias Mode (ACI)
Positive/negative Bias Mode (AUI)
Factory Setting: 0
Settings 0: Zero bias
1: Lower than or equal to bias
2: Greater than or equal to 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.

0: Negative frequency is not valid.
Forward and reverse run is controlled
by digital keypad or external terminal.
1: Neagtive frequency is valid. Positive
frequency = forward run; negative
frequency = reverse run. Direction
can not be switched by digital keypad or
external teriminal control.

2: Greater than or equal to bias
3: The absolute value of the bias voltage

4: Serve bias as the center
Lower than or equal to bias
