Example: When you set frequency gain for terminal A2
•
H3-10 = 1 [Terminal A2 Function Selection = Frequency Gain]
•
A 50% frequency gain is input to terminal A2
•
A frequency reference of 80% is input from terminal A1
The calculated frequency reference is 40% of the maximum output frequency.

2: Auxiliary Frequency Reference 1
Setting Value
Function
Description
2
Auxiliary Frequency
Reference 1
Sets Reference 2 through multi-step speed reference to enable the command reference (Auxiliary Frequency Reference 1) from the
analog input terminal set here. This value is a percentage where the Maximum Output Frequency setting is a setting value of 100%.
■
3: Auxiliary Frequency Reference 2
Setting Value
Function
Description
3
Auxiliary Frequency
Reference 2
Sets Reference 3 through multi-step speed reference to enable the command reference (Auxiliary Frequency Reference 2) from the
analog input terminal set here. This value is a percentage where the Maximum Output Frequency setting is a setting value of 100%.
■
4: Output Voltage Bias
Setting Value
Function
Description
4
Output Voltage Bias
Set this parameter to input a bias signal and amplify the output voltage.
The gain (%) for the MFAI terminals A1 and A2 is 100% of the voltage class standard, which is 208 V for 208/240 V
and 480 V for 480 V. The bias (%) for MFAI terminals A1 and A2 is 100% of the voltage configured for
E1-05
[Maximum Output Voltage]
.
Note:
Parameters
H3-03 [Terminal A1 Gain Setting]
and
H3-11 [Terminal A2 Gain Setting]
independently set the gain for each terminal A1 and
A2. Parameters
H3-04 [Terminal A1 Bias Setting]
and
H3-12 [Terminal A2 Bias Setting]
independently set the bias for each terminal A1 and
A2.

5: Accel/Decel Time Gain
Setting Value
Function
Description
5
Accel/Decel Time Gain
Enters a signal to adjust the gain used for
C1-01 to C1-04 [Acceleration/Deceleration Times 1 and 2]
and
C1-09 [Fast Stop Time]
when the full scale analog signal (10 V or 20 mA) is 100%.
When you enable
C1-01 [Acceleration Time 1]
, the acceleration time is:
Acceleration Time 1 = Setting value of
C1-01
× acceleration and deceleration time gain / 100
