(27) VCG IN Terminal
This is input terminal used to extemally control the frequency of the output from terminals
(9)and(12).
A
negative
voltage
applied
to
this
terminal
decreases
the
frequency,
and
a
positive
voltage
increases
it.
With
the
FREQ.
dial
set
to
"1
O”,
negative
voltage
is
applied
to
decrease
the
frequency
to
111000
(maximum
frequency
ratio).
The
maximum
input
voltage
is
+
10V
(AC
+
DC).
