overload/underload alarm;
1: The VFD continues running after underload
alarm, and stops running after overload fault;
2: The VFD continues running after overload alarm,
and stops running after underload fault;
3: The VFD 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 VFD 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
Setting range of P11.12: 0.1–3600.0s
