Chapter 4: AC Drive Parameters
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) Max. Output Frequency =
Motor Max. RPM (P0-04)
x Base Frequency (P0-02)
( Motor
Base RPM (P0-03) )
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
GS2 drive is 60Hz. If parameters P0.02, P0.03, or P0.04 are changed, then the
Maximum Output Frequency will change.
B) Analog Offset % =
C)
Analog Gain % =
D) Mid-point Freq. =
Min. Frequency Reference
x 100
( Max.
Frequency Reference )
Reference – Min. Frequency Reference
( Max. FrequencyMaximum
) x 100
Output Frequency
( Max. Freq. Reference 2– Min. Freq. Reference ) + Min. Freq. Reference
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.
