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
P01.03
Braking current
before start
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.

P01.05 ACC/DEC mode
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.

Note: If mode 1 is selected, set P01.06 , P01.07 ,
P01.27 , and P01.28 accordingly.
