Tens place:
0: The VFD continues to work for an OL/UL
alarm.
1: The VFD continues to work for a UL alarm but
stops running for an OL fault.
2: The VFD continues to work for an OL alarm
but stops r

Overload pre-
alarm
detection level
If the VFD or motor output current is larger than
the overload pre
-alarm detection level (P11.09),
and the duration exceeds the overlo
ad pre-
alarm
detection time (
P11.10), overload pre-alarm
signal will be outputted.
