P01.02
Retention
time of the
starting
frequency
Set a proper starting frequency to increase
the torque of the inverter during starting.
During the retention time of the starting
frequency, the output frequency of the
inverter is the starting frequency. And then,
the inverter will run from the starting
frequency to the set frequency. If the set
frequency is lower than the starting
frequency, the inverter 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 inverter 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 inverter.
