limit level
during running, and compares it with the current-limit
level defined by P11.06, if it exceeds the current-limit
level, the VFD will run at stable frequency during
accelerated running, or run in decreased frequency
during constant-speed running; if it exceeds the current-
limit level continuously, the VFD output frequency will
drop continuously until reaching lower limit frequency.
When the output current is detected to be lower than the
current-limit level again, it will continue accelerated
running.

Ones place:
0: Motor overload/underload pre-alarm, relative to rated
motor current
1: VFD overload/underload pre-alarm, relative to rated
VFD output current
2: VFD output torque overload/underload pre-alarm,
relative to rated motor torque
3: Motor overload/underload pre-alarm. The overload is
relative to the motor rated current; while the underload
is relative to the motor rated power.
4: VFD overload/underload pre-alarm. The overload is
relative to the VFD rated current; while the underload is
relative to the VFD rated power.
Tens place:
0: The VFD continues running after overload/underload
alarm.
1: The VFD continues running after underload alarm,
and stops running after overload fault.
2: The VFD continues running after overload alarm, and
stops running after underload fault.
3: The VFD stops running after overload/underload
fault.
Hundreds place:
0: Always detect
1: Detect during constant-speed running
