2.8 H: Terminal Function Selection
YASKAWA TOEPYAIGA5002A GA500 Programming 335
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 A2 Signal Level
Select
Sets the input signal level for MFAI terminal A2.
2
(0, 2 - 4)
0 : 0-10V (LowLim=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%.
2 : 4 to 20 mA
The current signal is 4 mA to 20 mA. 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 is limited to 0%, so that a negative input signal due to
gain and bias settings will be read as 0%.
4 : -10 to +10V (Bipolar Reference)
The voltage signal is -10 Vdc to 10 Vdc. Signals of both positive and negative polarities are enabled. When this
setting is used as the frequency reference, the motor runs reverse when the Forward run command is input, or runs
forward when the Reverse run signal is input, while the signal is a negative number due to gain and bias.
Note:
When H3-09 = 0, 4, set DIP switch S1 to the V side (voltage). When H3-09 = 2, 3, set DIP switch S1 to the I side (current). The default
setting is the I side (current).

Terminal A2 Gain Setting
Sets the gain of the analog signal input to MFAI terminal A2.
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 A2 as a
percentage.
Use this parameter and H3-12 [Terminal A2 Bias Setting] to adjust the characteristics of the analog input signal to
terminal A2.

Terminal A2 Bias Setting
Sets the bias of the analog signal input to MFAI terminal A2.
0.0%
(-999.9 - +999.9%)
When 0 V (4 mA or 0 mA) is input, this parameter sets the bias for the function set for terminal A2 as a percentage.
