AI1 Bias Setting
Sets the bias of the analog signal input to MFAI terminal AI1.
0.0%
(-999.9 - +999.9%)
This parameter sets the bias for the function set for terminal AI1 as a percentage when 0 V (4 mA or 0 mA) is
input.
Use this parameter and H3-03 [AI1 Gain Setting] to adjust the characteristics of the analog input signal to
terminal AI1.

AI3 Signal Level Select
Sets the input signal level for MFAI terminal AI3.
0
(0 - 3)
0 : 0 to 10V (Lower Limit at 0)
The voltage signal is 0 Vdc to 10 Vdc. The minimum input level limit is 0%. The drive will read a negative input
signal caused by gain and bias settings as 0%.
1 : -10 to +10V (Bipolar Reference)
The voltage signal is -10 Vdc to 10 Vdc. This setting enables positive and negative polarity signals. When the
drive uses this setting as the frequency reference, a Forward Run command will run the motor in reverse and a
Reverse Run command will run the motor forward. The gain and bias settings will cause the signal to be a
negative number.
2 : 4 to 20 mA
The current signal is 4 mA to 20 mA. The minimum input level limit is 0%. The drive will read a negative input
signal caused by gain and bias settings as 0%.
3 : 0 to 20 mA
The current signal is 0 mA to 20 mA. The minimum input level limit is 0%. The drive will read a negative input
signal caused by gain and bias settings as 0%.
Note:
When H3-05 = 0, 1, set DIP switch S1-3 to the V side (voltage). When H3-05 = 2, 3, set DIP switch S1-3 to the I side (current). The
default setting is the V side (voltage).

(0 - 32)
Note:
When terminal AI3 is the PTC input terminal:
• Set H3-06 = 16 [Mot PTC InputMotor Temperature (PTC input)]
• Set DIP switch S4 to the PTC side
• Set DIP switch S1-3 to the V side
■ H3-07 AI3 Gain Setting

RUN
AI3 Gain Setting
Sets the gain of the analog signal input to MFAI terminal AI3.
100.0%
(-999.9 - +999.9%)
When 10 V (or 20 mA) is input, this parameter sets the reference quantity for the function set for terminal AI3 as
a percentage.
Use this parameter and H3-08 [AI3 Bias Setting] to adjust the characteristics of the analog input signal to terminal
AI3.
