F20.02 defines the time during which the inverter output current exceeds overload pre-alarm detection
threshold (F20.01). If the status remains after overload pre-alarm detection time (F20.02), the inverter
will output pre-alarm signal.

0: Disabled. It does not detect inverter output load-loss.
1: It is detecting all the time in running process, and then continues operation after detecting (alarm).
2: It detectes only at the same speed, and then continues operation after detecting (alarm).
3: It is detecting all the time in running process, and then cut off the output after detecting (fault).
4: It is detectes only at the same speed, and then cut off the output after detecting (fault).

F20.04 defines the current threshold of load-loss. It is a percentage of the inverter’s rated current.

If the inverter’s output current is smaller than the load-loss detection threshold (F20.04) beyond the
time defined by load-loss detection time (F20.05), the inverter will alarm inverter load-loss fault
(E0018).
• When F20.04 or F20.05 is set to 0, the inverter will not detect load loss fault.

F20.08 value is a percentage of the inverter’s rated voltage.
• When F20.08 is set to 0, the inverter will not detect input phase loss fault.
When the inverter detects certain input voltage not hit the preset detection reference (F20.08) and
exceed the preset detection time (F20.09), the inverter will perform input phase loss alarm (E0015).

F20.10 value is a percentage of the inverter’s rated current.
When the inverter detects certain output current not hit the preset detection reference (F20.10) and
exceed the preset detection time (F20.11), the inverter will perform output phase loss alarm (E0016).
• When F20.10 or F20.11 is set to 0, the inverter will not detect output phase loss fault.
