1: The inverter continues running after underload
alarm, and stops running after overload fault;
2: The inverter continues running after overload
alarm, and stops running after underload fault;
3: The inverter stops running after
overload/underload fault.
Hundreds:
0: Always detect
1: Detect during constant-speed running
Setting range of P11.09: P11.11–200%
Setting range of P11.10: 0.1–3600.0s
P11.11
Underload
pre-alarm
detection level
Underload pre-alarm signal will be outputted if the
output current of the inverter or motor is lower
than underload pre-alarm detection level
(P11.11), and the duration exceeds underload
pre-alarm detection time (P11.12).
Setting range of P11.11: 0– P11.09

This function code is used to set the action of fault
output terminals during undervoltage and fault
reset.
