Description
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.

P11.09 setting range: P11.11–200.0%
P11.10 setting range: 0.1–3600.0s
Underload pre-alarm signal will be outputted if
the output current of the VFD or motor is lower
than underload pre-alarm detection level
(P11.11), and the duration exceeds underload
pre-alarm detection time (P11.12).
P11.11 setting range: 0%–P11.09
Setting range of P11.12: 0.1–3600.0s
Used to set the action of fault output terminals at
undervoltage and fault reset.
0x00–0x11
Ones place:
0: Act upon an undervoltage fault
1: Do not act upon an undervoltage fault
Tens place:
0: Act during automatic reset
1: Do not act during the automatic reset period
0.0–50.0%
Used to set the speed deviation detection value.
0.0–10.0s (No speed deviation protection for the
value=0.0)
Used to set the speed deviation detection time.
