signals.
3: Overload detection
When the inverter’s output current exceeds the overload alarm level, after the set
alarm delay time, it outputs effective signals. When the inverter’s output current
is lower than the overload alarm level, after the same delay time, it outputs void
signals.
4: Frequency reaching upper limit
When the inverter’s output frequency reaches the upper limiting frequency, this
terminal outputs effective signals; otherwise, it outputs void signals.
5: Frequency reaching lower limiting
When the inverter’s output frequency reaches the lower limiting frequency, this
