7-3 Description of Functions
●
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: F1401=0.0(0Hz),
F1402=50.0(50Hz)
Setting of 2nd inverter: F1401=0.0(0Hz),
F1402=100.0(100Hz)
(Adjust the acceleration/deceleration time as required.)
Note 1: In negative setting frequency field, the output frequency is 0Hz.
Note 2: For PID control, the bias and gain frequencies apply to the feedback signal.

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.
