Setting range: 0.0–50.0s
P01.03
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.
The setting range of P01.03: 0.0–100.0%
