2: inverter output torque overload/underload
pre-alarm, relative to rated motor torque
Tens place:
0: The inverter continues running after
overload/underload alarm.
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 place:
0: Always detect
1: Detect during constant-speed running
Thousands place: inverter overload current
reference selection
0: Related to current calibration coefficient
1: Irrelated to current calibration coefficient

level
If the inverter 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.

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 ).
