Detailed instruction of parameters
starting.
2: Start after speed tracking 1
3: Start after speed tracking 2
The direction and speed will be tracked
automatically for the smoothing starting of
rotating motors. It suits the application with
reverse rotation when big load starting.
Note: This function is only available for the
inverters≥4kW
Starting
frequency
of direct
start-up
Starting frequency of direct start-up means the
original frequency during the inverter starting.
See P01.02 for detailed information.
Setting range: 0.00~50.00Hz
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.
Setting range: 0.0~50.0s
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.
The setting range of P01.03: 0.0~100.0%
The setting range of P01.04: 0.00~50.00s
The braking
time before
starting
The changing mode of the frequency during
start-up and running.
0:Linear type
The output frequency increases or decreases
