By taking advantage of bias and gain frequencies, a common analog signal for frequency commands can be input to more than one
inverter for proportional operation.
Example) Input 0 - 10V analog signals to two inverters, so that 1st and 2nd inverters deliver output frequencies with a ratio of 1:2
for the purpose of proportional operation.
Setting of 1st inverter:
Setting of 2nd inverter:
(Adjust the acceleration/deceleration time as required.)
Note 1: In negative setting frequency field, the output frequency is 0 Hz.
Note 2: For PID control, the bias and gain frequencies apply to the feedback signal.
F1407
External analog input filter time constant
F1408
External analog input filter time constant
（VRF/IRF）
Functions for setting the filter time constant of external analog signal input.
Code No. Function Name
F1407 External analog input filter time
constant
（VRF1）
F1408
External analog input filter time
constant
（VRF/IRF）
If interference is detected in external analog signals, adjust the external analog input filter time constant.
Set the time constant to N × 10 ms (N = 1 to 500), the setting range is 10 to 5,000 ms.
Filters can be assigned to VIF1, VIF2 and VIF3 independently.
Set frequency gain
F1410
Analog input switching for set
F1411
frequency gain
Using an external analog input terminal, the gain is adjustable when setting frequency.
Code No. Function Name
F1410 Set frequency gain
F1411 Analog input switching for set
frequency gain
● When several inverters are used for proportional operation, this function is useful for fine adjustment of the command frequencies
of the inverters from the master to the slave.
● The external analog input terminal is switched with F1411 (Analog input switching for set frequency gain).
● Use F1410 as the set frequency value for proportional operation.
Example 2) When the set frequency is 50Hz, F1410 = 50%, if the external analog input is 0 - 10V
F1401=0.0（0 Hz）,
F1402=50.0（50 Hz）
F1401=0.0（0 Hz）,
F1402=100.0（100 Hz）
