0: Start-up directly: start from the starting frequency
P01.01
1: Start-up after DC braking: start the motor from the
starting frequency after DC braking (set the
parameter P01.03 and P01.04). It is suitable in the
cases where reverse rotation may occur to the low
inertia load during starting.
2: Start-up after speed tracing: start the rotating
motor smoothly after tracking the rotation speed and
direction automatically. It is suitable in the cases
where reverse rotation may occur to the big inertia
load during starting.

P01.01
Starting
frequency of
direct start
Starting frequency of direct start-up means the
original frequency during the VFD starting. See
P01.02 for detailed information.
Setting range: 0.00

P01.02
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
