Terminal A3 Function
Selection
Sets the function for MFAI terminal A3.
2
(0 - 32)
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
■ H3-07: Terminal A3 Gain Setting

Terminal A3 Gain Setting
Sets the gain of the analog signal input to MFAI terminal A3.
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 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

RUN
Terminal A3 Bias Setting
Sets the bias of the analog signal input to MFAI terminal A3.
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 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

Terminal A2 Signal Level
Select
Sets the input signal level for MFAI terminal A2.
2
(0 - 3)
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).
