YASKAWA GA700 Technical Manual page 805

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%.
Note:
When H3-09 = 0, 1, set DIP switch S1-2 to the V side (voltage). When H3-09 = 2, 3, set DIP switch S1-2 to the I side (current). The
default setting is the I side (current).

Parameter H3-03 sets the reference amount for the function set for terminal A2 as a percentage when 10 V (or 20
mA) is input.
AUse H3-11 and H3-12 [Terminal A2 Bias Setting] to adjust the characteristics of the analog input signal to
terminal A2.

H3-12 Terminal A2 Bias
Setting
(041A)
RUN
This parameter sets the bias for the function set for terminal A2 as a percentage when 0 V (4 mA or 0 mA) is
input.
Use H3-11 [Terminal A2 Gain Setting] and H3-12 to adjust the characteristics of the analog input signal to
terminal A2.

H3-13 Analog Input
FilterTime Constant
(041B)
Applying the primary delay filter to the analog input enables an analog input signal without high-frequency noise
components to be obtained. An analog input filter prevents erratic drive control. Drive operation becomes more
stable as the programmed time becomes longer, but it also becomes less responsive to rapidly changing analog
signals.

V/f CL-V/f OLV CLV AOLV
Selects a function set to the MFAI terminal A2.
V/f CL-V/f OLV CLV AOLV
Sets the gain of the analog signal to be input to the MFAI terminal A2.
V/f CL-V/f OLV CLV AOLV
Sets the bias of the analog signal to be input to the MFAI terminal A2.
V/f CL-V/f OLV CLV AOLV
Sets the time constant when applying a primary delay filter to the MFAI
terminal.
V/f CL-V/f OLV CLV AOLV
Selects the enabled terminal Sx when H1-xx = C [Terminal Sx Function
Selection = Analog Terminal Enable Selection] is ON. Also selects the
disabled terminal Sx when the input is OFF.
