Description
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
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.
Setting range of P01.03: 0.0–100.0%
Setting range of P01.04: 0.00–50.00s
The function code indicates the changing
mode of the frequency during start and
running.
