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.
PI500 provides two group of sets of parameter for Randomly Reaches Current and Detection
Width, the figure is the functional diagram.

Module temperature arrival
When the inverter radiator temperature reaches the temperature, the inverter multifunction
DO will output "Module Temperature Arrival" ON signal.
Fan running only when running
Used to select the cooling fan mode, if you select 0, the fan will run when the inverter is
running, but in the stop state of inverter, if the radiator temperature is above 40 degrees, the fan
will run, otherwise the fan will not run.If you select 1, when the fan will always running after
power-on.
Noted: The fan of PI500 will be uncontrolled.
