Display Setting Description Setting Setting
*F_35 0.00 GAIN FOR FREQUENCY SETTING SIGNAL 100.0%
to This sets the size (gradient) of the output frequency
250 corresponding to the analog frequency setting as a
percentage of the maximum frequency.
[Example: for 70% gain] [Example for 200% gain]
*The gain setting is only active when F_01 = 1
Example:
If the bias frequency function (F_34) and the gain for
frequency setting signal function (F_35) are used together,
the gain for frequency setting signal has priority, and the
bias is applied to the frequency with gain already applied.
The bias frequency f
bias and setting frequency gain at
this time can be calculated by the following formulas.
f

– f

f bias = f 1 – x V 1
V 1 – V 2
1000 x (f 1 – f 2 )
Gain =
100 x (V

Example:
If the analog frequency setting voltage is 1 to 5Vdc
and the output frequency is weighted to 0 to 100% then:
(V 1 , f 1 ) = ( 1, 0) , (V2, f2) = ( 5,100), so that
