P11.09 setting range: P11.11–200% (relative
value determined by the ones place of P11.08)
Setting range of P11.10: 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
(P11.11), and the duration exceeds underload
pre-alarm detection time (P11.12).
P11.11 setting range:
determined by the ones place of P11.08)
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 at undervoltage
1: Do not act at undervoltage
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.
Setting range: 0.0–10.0s (0.0 indicates no
speed deviation protection)
Used to set the speed deviation detection time.
Note: Speed deviation protection is invalid
when P11.15=0.0.
