The parameter set the inverter protective action mode when it
is overload or overheat.
0 The inverter locks output immediately . When it is overload
or overheat, the inverter locks output and the motor coasts to
stop .
：
1 Limitative current running alarm . When it is overload
or overheat , the inverter is limitative current mode,
and the inverter might reduce the output frequency to decrease
the load current

30.0 100.0%～
The value is equal to motor rated current/inverter rated current .
When the inverter output current exceeds F8.03 multiply the
inverter rated output current for a certain time , the inverter
reports motor overload fault .
110 200%～
120 150%～
Select the protection point for the stall over current function.
When the value is exceeded , the inverter starts executing the
protection function for stall over current .
Select the protection point for the stall over voltage .
When the value is exceeded , the inverter starts executing the
protection function for stall over voltage .
function
The reference for this value is the inverter rated current .
When the inverter detects that the output current exceeds
the parameter F8.00 ,
it outputs pre-warning signal from OC or relay,
.
corresponding current of continuously
after the
delayed time of F8.01
When restart after power-off is enabled ,inverter is on the
running state before power cut. Then the inverter will start
automatically after the setup waiting time (it is set by F8.07)
when power-on .During the restart waiting time ,
even though there inputs run command, if there
inputs stop command , it will finish the restart waiting state .
the inverter
won’t start,

When the inverter selects fault automatical reset , it is used to set
the times of automatical reset .If the value is exceeded , the
inverter will stop because of failure and wait for maintenance .
The waiting time of the inverter from the fault alarm to automatical
reset .
