powering on. If the running command is detected to
be valid during powering on, the system will start the
VFD automatically after the initialization.
Note: this function should be selected with cautions,
or serious result may follow.
This function code determines the running state of
the VFD when the set frequency is lower than the
lower-limit one.
0: Run at the lower-limit frequency
1: Stop
2: Hibernation
3: Run at zero frequency
The VFD will coast to stop when the set frequency is
lower than the lower-limit one. If the set frequency is
above the lower limit one again and it lasts for the
time set by P01.20, the VFD will come back to the
running state automatically.
This function code determines the hibernation delay
time. When the running frequency of the VFD is
lower than the lower limit one, the VFD will pause to
stand by.
When the set frequency is above the lower limit one
again and it lasts for the time set by P01.20, the VFD
will run automatically.

This function can enable the VFD start or not after
the power off and then power on.
