Analog Input Selection (AI)
D
efault: 1
S
ettings 0: No function
1:
Frequency command
4:
PID target value
5:
PID feedback signal
6:
Thermistor (PTC) input value
1
1: PT100 thermistor input value
12:
Auxiliary frequency input
13:
PID compensation value
 When you use analog input as the PID reference target input, you must set Pr.00-20 to 2
(external analog input).
Setting method 1: Pr.03-00 set 1 as frequency command.
Setting method 4: Pr.03-00 set 4 as PID reference target input.
 When you use analog input as the PID compensation value, you must set Pr.08-16 to 1 (source
of PID compensation value is analog input). You can see the compensation value with Pr.08-17.
 When you use the frequency command, the corresponding value for 0– ±10 V / 4–20 mA is 0–
maximum operation frequency (Pr.01-00).

Analog Input Bias (AVI)
Default: 0
Settings -100.0–100.0%
 Sets the corresponding AVI voltage for the external analog input 0.

03-04
Analog Input Bias (ACI)
D
efault: 0
S
ettings -100.0–100.0%
 Sets the corresponding ACI voltage for the external analog input 0.

03-07
Positive / Negative Bias Mode (AVI)

03-08
Positive / Negative Bias Mode (ACI)
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
 In a noisy environment, use negative bias to provide a noise margin. Do NOT use less than 1 V
to set the operation frequency.
