P11.08
Pre-alarm
selection for
VFD/motor
OL/UL
If the VFD or motor output current is larger
than the overload pre-alarm detection level
(P11.09), and the duration exceeds the
overload pre-alarm detection time (P11.10),
overload pre-alarm signal will be outputted.

P11.08 setting range: 0x000–0x131
Used to enable and define the overload
pre-alarm function of the VFD and the motor.
Ones place:
0: Motor OL/UL pre-alarm, relative to the
rated motor current.
1: VFD OL/UL pre-alarm, relative to the VFD
rated current
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 running for a UL fault.
3. The VFD stops running for an OL/UL
alarm.
Hundreds place:
0: Detect all the time.
1: Detect during constant speed running.
P11.09 setting range: P11.11–200.0%
