12.1-03-3
 The wiring of KTY-84 as shown below

03-03
AVI Analog Input Bias
Default: 0.0
Settings -100.0–100.0%
 Set the corresponding AVI voltage for the external analog input 0.

03-04
ACI Analog Input Bias
Default: 0.0
Settings -100.0–100.0%
 Set the corresponding ACI current for the external analog input 0.

03-05
AUI Analog Input Bias
Default: 0.0
Settings -100.0–100.0%
 Set the corresponding AUI voltage for the external analog input 0.
 The corresponding external input voltage / current signal and the set frequency is 0–10 V (4–20
mA) corresponds to 0–maximum frequency.

03-07
AVI Positive / Negative Bias Mode

03-08
ACI Positive / Negative Bias Mode

03-09
AUI Positive / Negative Bias Mode
Default: 0
Settings 0: No 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: Bias serves as the center
 Using negative bias to set the frequency greatly reduces the noise interference. In a noisy
environment, do NOT use signals less than 1 V to set the drive’s operation frequency.
