Terminal A3 Signal
Level Select
Sets the input signal level for MFAI terminal A3.
0
(0, 1)
0 : 0 to 10 V (Lower Limit at 0)
Inputs the voltage signal of 0 V to 10 V. The signal is reset to 0% when it becomes a negative number due to gain
and bias adjustment.
1 : -10 to +10V (Bipolar Reference)
Inputs the voltage signal of -10 V to 10 V. This setting enables positive and negative polarity signals. 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 the gain and bias
adjustment.

Note:
When using terminal A3 as the PTC input terminal, set
H3-06 = E [Motor Temperature (PTC Input)]
, and set DIP switch S4 to the PTC
side.

RUN
Terminal A3 Gain
Setting
Sets the gain of the analog signal input to MFAI terminal A3.
100.0%
(-999.9 - +999.9%)
This parameter sets the command reference amount for the function set for terminal A3 as a percentage when 10
V is input.
Use
H3-07 and H3-08 [Terminal A3 Bias Setting]
to adjust the characteristics of the analog input signal to
terminal A3.

RUN
Terminal A3 Bias
Setting
Sets the bias of the analog signal input to MFAI terminal A3.
0.0%
(-999.9 - +999.9%)
This parameter sets the bias for the function set for terminal A3 as a percentage when 0 V is input.
Use
H3-07 [Terminal A3 Gain Setting] and H3-08
to adjust the characteristics of the analog input signal to
terminal A3.

(0 - 3)
0 : 0 to 10 V (Lower Limit at 0)
Inputs the voltage signal of 0 V to 10 V. The signal is reset to 0% when it becomes a negative number due to gain
