again and it lasts for the time set by P01.20,
the inverter will come back to the running
state automatically.
This function code determines the hibernation
delay time. When the running frequency of
the inverter is lower than the lower limit one,
the inverter will stop 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 inverter will run automatically.
Set frequency
t1<t3, so the inverter does not work
t1+t2=t3, so the inverter works
t3=P01.20
Running
Setting range: 0.0–3600.0s (valid when
P01.19=2)
This function can enable the inverter start or
not after the power off and then power on.
0: Disabled
1: Enabled, if the starting need is met, the
inverter will run automatically after waiting for
the time defined by P01.22.
The function determines the waiting time
before the automatic running of the inverter
when powering off and then powering on.
