5.2 F1 Group: Start and Stop Parameters
F1.00
Start mode Factory Setting 0
Setting Options
0 Start directly
1 DC braking first and then start
2 Speed tracing and start
0: Start directly: start from the frequency of start.
1: DC braking first and then start: DC braking first according to the set mode of
F1.03 and F1.04, then start from the frequency of start. This is suitable for the
occasion that the small inertial load may cause inversion at start up.
2: Speed tracing and start
The VFD will judge the rotational speed and direction of the electric motor, and then
start at relevant frequency traced from the rotational speed of the electric motor, thus
the rotating electric motor can start smoothly without surge. This is suitable for the
occasion that the large inertial load power off suddenly and start up again.
In order to ensure the performance of speed tracing and start, accurate parameters
for electric motor should be set. (See F2 group)
F1.01
Start frequency Factory Setting 1.50Hz
Setting Scope
0.00～10.00Hz
F1.02
Hold time of start frequency Factory Setting 0.0s
Setting Scope
0.0～50.0s
The VFD operates from the start frequency (F1.01), after the hold time of start
frequency (F1.02), the VFD will accelerate to the target frequency according to the
set time of acceleration. If the target frequency is lower than the start frequency,
the VFD will be in standby mode. The start frequency will not be restricted by the
lower limit frequency.
