12.8 H: Terminal Functions
YASKAWA SIEPC71061705H GA700 Series Technical Manual 847
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).

Terminal A1 Gain Setting
Sets the gain of the analog signal input to MFAI terminal A1.
100.0%
(-999.9 - +999.9%)
This parameter sets the quantity of reference for the function set for terminal A1 as a percentage when 10 V (or 20
mA) is input.
Use this parameter and H3-04 [Terminal A1 Bias Setting] to adjust the characteristics of the analog input signal to
terminal A1.

Terminal A1 Bias Setting
Sets the bias of the analog signal input to MFAI terminal A1.
0.0%
(-999.9 - +999.9%)
This parameter sets the bias for the function set for terminal A1 as a percentage when 0 V (4 mA or 0 mA) is
input.
Use this parameter and H3-03 [Terminal A1 Gain Setting] to adjust the characteristics of the analog input signal to
terminal A1.

Terminal A3 Signal Level
Select
Sets the input signal level for MFAI terminal A3.
0
(0 - 3)
0 : 0-10V (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. Signals of both positive and negative polarities are enabled. 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 minimum input level is limited to
0%, so that a negative input signal due to gain and bias settings will be read as 0%.
3 : 0 to 20 mA
The current signal is 0 mA to 20 mA. The minimum input level limit is 0%. The minimum input level is limited to
0%, so that a negative input signal due to gain and bias settings will be read 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).
