forward.
Indicates the inverter is running forward with output frequency.
Here output ON signal
2
Inverter is
running reverse
Indicates the inverter is running reverse with output frequency.
Here output ON signal

Fault output
Once inverter fault happens, output ON signal
4
Motor overload
pre- warning
Before motor electronic thermal protection is active, it is judged
according to predicted overload value. Once the pre-warning
time is exceeded, output ON signal. Overload parameter is set
up at PB.04-PB.06.

Inverter
overload pre-
warning
Based on inverter pre-warning point, once the pre-warning
time is exceeded, output ON signal. Overload parameter is set
up at PB.04-PB.06.
