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.

RUN
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.

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%.
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 H3-05 = 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).

Note:
When terminal A3 is the PTC input terminal:
• Set H3-06 = E [Motor Temperature (PTC input)]
• Set DIP switch S4 to the PTC side
• Set DIP switch S1-3 to the V side
