Analog Input Examples
Use the equations below when calculating the values for the Maximum Output
Frequency, Analog Input Offset, Analog Input Gain, and the Mid-point Frequency.
A)
Note: The Maximum Output Frequency is not a parameter setting but is needed in order
to calculate the Analog Gain. The default Maximum Output Frequency for the GS1 drive
is 60Hz. If parameters 0-02, 0-03, or 0-04 are changed, then the Maximum Output
Frequency will change.
B)
C)
D)
Note: The Mid-point Frequency calculation shows the frequency reference of the drive
when the potentiometer or other analog device is at its mid-point.
