Chapter 6 - Parameter Description [FU1]
6-16
FU1-33: Frequency Limit Selection
FU1-34: Low Limit Frequency
FU1-35: High Limit Frequency
FU1-33 selects the limits the inverter operating
frequency. If FU1-33 is set to ‘Yes’, inverter operates
within the upper and lower limit setting. The inverter
operates at the upper or the lower limit when the
frequency reference is outside the frequency limit
range.
[Freq. limit: ‘Yes’]
Note: if freq set value is below freq low limit,
inverter operates at the low limit.
Note: Normal Accel/Decel is performed for the
range below low limit during Accel/Decel.
FU1-40: Volts/Hz Pattern
This is the pattern of voltage/frequency ratio. Select
the proper V/F pattern according to the load. The
motor torque is dependent on this V/F pattern.
[Linear] pattern is used where constant torque is
required. This pattern maintains a linear
volts/frequency ratio from zero to base frequency.
This pattern is appropriate for constant torque
applications. The performance will be improved with
the help of FU2-67~69 [Torque boost].
[Square] pattern is used where variable torque is
required. This pattern maintains squared volts/hertz
ratio. This pattern is appropriate for fans, pumps, etc.
[User V/F] pattern is used for special applications.
Users can adjust the volts/frequency ratio according
to the application. This is accomplished by setting the
voltage and frequency, respectively, at four points
between starting frequency and base frequency. The
four points of voltage and frequency are set in FU1-
41 through FU1-48.
