12.7 H: TERMINALS
SIEPYEUOQ2A01A AC Drive Q2A Technical Manual 713
Note:
• Refer to H3-xx “MFAI Setting Values” for the analog input setting values.
• When you will not use the terminal, set H3-40 to H3-42 = 0. The through mode function is not supported.
• You cannot use H3-40 to H3-42 to set these MFAI terminals:

AI1 Signal Level Select
Sets the input signal level for MFAI terminal AI1.
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 H3-01 = 0, 1, set DIP switch S1-1 to the V side (voltage). When H3-01 = 2, 3, set DIP switch S1-1 to the I side (current). The
default setting is the V side (voltage).

RUN
AI1 Gain Setting
Sets the gain of the analog signal input to MFAI terminal AI1.
100.0%
(-999.9 - +999.9%)
This parameter sets the quantity of reference for the function set for terminal AI1 as a percentage when 10 V (or
20 mA) is input.
Use this parameter and H3-04 [AI1 Bias Setting] to adjust the characteristics of the analog input signal to terminal
AI1.
