When the inverter's output current is more than or overrun the detection point and lasts
for longer than the delay time of software overcurrent point detection, the inverter's
multifunction DO will output ON signal.

When the inverter's output current randomly reaches the range of the current detection
width(positive or negative), the inverter multifunction DO will output ON signal.
PI9000 provides two group of sets of parameter for Randomly Reaches Current and
Detection Width, the figure is the functional diagram.
