(Hex.)
H3-07 Terminal A3 Gain Setting
(0415)
RUN
When 10 V (or 20 mA) is input, this parameter sets the reference quantity for the function set for terminal A3 as a
percentage.
Use this parameter and H3-08 [Terminal A3 Bias Setting] to adjust the characteristics of the analog input signal to
terminal A3.

H3-08: Terminal A3 Bias Setting
No.
Name
(Hex.)
H3-08 Terminal A3 Bias Setting
(0416)
RUN
When 0 V (4 mA or 0 mA) is input, this parameter sets the bias for the function set for terminal A3 as a percentage.
Use this parameter and H3-07 [Terminal A3 Gain Setting] to adjust the characteristics of the analog input signal to
terminal A3.

H3-09 Terminal A2 Signal Level
Select
(0417)
0 : 0-10V (Lower Limit at 0)
The voltage signal is 0 Vdc to 10 Vdc. 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%.
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 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.
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%.
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).
