H3-08 AI3 Bias Setting
No.

H3-08
(0416)
RUN
AI3 Bias Setting
Sets the bias of the analog signal input to MFAI terminal AI3.
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 AI3 as a
percentage.
Use this parameter and H3-07 [AI3 Gain Setting] to adjust the characteristics of the analog input signal to
terminal AI3.

AI2 Signal Level Select
Sets the input signal level for MFAI terminal AI2.
2
(0 - 3)
0 : 0 to 10V (Lower Limit at 0) (Q2V: 0 to 10 V with zero limit)
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) (Q2V: 0 to 10 V without zero limit)
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 (Q2A Only)
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 (Q2A Only)
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).

AI2 Gain Setting
Sets the gain of the analog signal input to MFAI terminal AI2.
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 AI2 as
a percentage.
Use this parameter and H3-12 [AI2 Gain Setting] to adjust the characteristics of the analog input signal to
terminal AI2.
