VFD500 high performance vector control frequency inverter user manual
02 Group Start and stop Control
Description
0：Direct start
Inverter will start from P02.01,After P02.02,It
will go to setting frequency as per S curve
1：Speed tracking/Searching
Inverter will do search for motor speed and
recognize and accelerate and decelerate to
setting frequency. See Parameter P02.16-
P02.19
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.
0.00Hz～10.00Hz
0.000s～10.000s
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.
0：Disable
