1: The inverter continues to work after
underload pre-alarm and the inverter stops to
run after overload fault
2: The inverter continues to work after
overload pre-alarm and the inverter stops to
run after underload fault
3. The inverter stops when overloading or
underloading.
LED hundreds :
0: Detection all the time
1: Detection in constant running
Setting range of P11.09: P11.11–200%
Setting range of P11.10: 0.1–3600.0s
P11.11
Detection
level of the
underload
pre-alarm
If the inverter current or the output current is
lower than P11.11, and its lasting time is
beyond P11.12, the inverter will output
underload pre-alarm.
Setting range of P11.11: 0–P11.09
Setting range of P11.12: 0.1–3600.0s
