f007 Maximum frequency 30.0 ~ 400.0 Hz 50.0
f008 Upper limit frequency 0.5 Hz ~f007 50.0
f009 Lower limit frequency 0.0 Hz ~f008 0.0
f007 sets the range of frequencies output by the inverter (maximum output values). This
frequency is used as the reference for acceleration/deceleration time.
f008 and f009 set the upper and lower limit frequency that determines motor rotation
speed range.
Figure 2.2 Relation of f007, f008, f009and running speed
Note1:Set f007、f008、f009 carefully. The motor output frequency is affected not only by
these three parameters, but also by start frequency, DC braking initial frequency
and skip frequency.
Note 2: The following condition must be true when setting up these parameters: f009≤
f008 ≤ f007.
NO. Parameter Name Setting Range Default
f010 Acceleration time 1 0.0 ~ 3200 s varies by model
f011 Deceleration time 1 0.0 ~ 3200 s varies by model
f010 sets the time that it takes for the inverter output frequency to go from 0Hz to
maximum frequency f007.
f011 programs the time that it takes for the inverter output frequency to got from
maximum frequency f007 to 0.0Hz.
