Goodrive3000 series medium voltage VFD
Function
code
Starting frequency
P01.02
Setting a proper starting frequency can increase the torque during VFD start. During the hold time of the starting frequency,
the output frequency of the VFD is the starting frequency. And then, the VFD runs from the starting frequency to the set
frequency. If the set frequency is lower than the starting frequency, the VFD stops running and keeps in the standby state.
The starting frequency is not limited in the lower limit frequency.
Function
code
P01.03
Braking time before
P01.04
The VFD performs DC braking with the braking current before start and it speeds up after the DC braking time. If the set
DC braking time is 0, DC braking is invalid.
Stronger braking current indicates larger braking power. The DC braking current before start is a percentage of the VFD
rated current.
Function
code
P01.05
The function code is used to indicate the changing mode of the frequency during start and running.
0: Linear type. The output frequency increases or decreases linearly.
1: S curve. The output frequency increases or decreases according to the S curve.
The S curve is generally applied to elevators, conveyors, and other application scenarios where smoother start or stop is
required.
