6.5.2 Setting frequency command characteristics
 : Analog/logic input selection (VI terminal)
 : VI Input point 1 setting
 : VI Input point 1 frequency
 : VI Input point 2 setting
 : VI Input point 2 frequency
 : Analog input filter
 Function
Output frequency is adjusted in relation to frequency command according to external analog signals.
Analog signal is  set to 0: 0 to 10Vdc, 1: 4 to 20mAdc, 3: 0 to 5Vdc.
 analog input filter is effective for eliminating noise from frequency setting circuit. Increase if
operation cannot be done because noise effects stability.
 To fine adjust the frequency command characteristics for VI input, use the parameters f470 and f471.
(Refer to section 6.5.4)
