GD200A series VFD Function parameters
-41-
cases where reverse rotation may occur to the big
inertia load during starting.
Note: This function is available for the 004G/5R5P
and higher models.
Starting
frequency of
direct start
Starting frequency of direct start means the
original frequency during the VFD starting. See
P01.02 for detailed information.
Setting range: 0.00–50.00Hz
Retention time
of the starting
frequency
Set a proper starting frequency to increase the
torque of the VFD during starting. During the
retention time of the starting frequency, the output
frequency of the VFD is the starting frequency.
And then, the VFD will run from the starting
frequency to the set frequency. If the set
frequency is lower than the starting frequency, the
VFD will stop running and keep in the stand-by
state. The starting frequency is not limited in the
lower limit frequency.

The braking
current before
starting
The VFD will carry out DC braking at the braking
current set before starting and it will speed up after
the DC braking time. If the DC braking time is set
to 0, the DC braking is invalid.
The stronger the braking current, the bigger the
braking power. The DC braking current before
starting means the percentage of the rated current
of the VFD.
Setting range of P01.03: 0.0–100.0%
Setting range of P01.04: 0.00–50.00s
The braking
time before
starting
The changing mode of the frequency during start
and running.
0: Linear type
The output frequency increases or decreases
linearly.
