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)
