Description
0: Direct start: start from the starting
frequency P01.01.
1: Start 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: Speed tracking restart: The direction and
speed will be tracked automatically for the
smoothing starting of rotating motors. It is
suitable in the cases where reverse rotation
may occur to the high inertia load during
starting.
Note: The function is available only for 4kW
and higher models.
The function code indicates the initial
frequency during VFD start. See P01.02
(Starting frequency hold time) for detailed
information.

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.
Setting range: 0.0–50.0s
