When the inverter's output current is more than or overrun the detection point and lasts for
longer than the delay time of software over-current point detection, the inverter's multi-function
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 multi-function DO will output ON signal.
PI500-E provides two group of sets of parameter for Randomly Reaches Current and
Detection Width, the figure is the functional diagram.

When the inverter radiator temperature reaches the temperature, the inverter multi-function
DO will output "Module Temperature Arrival" ON signal.

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. When select 1, when the fan will always running after
power-on.

The group of parameters are used to complete the inverter timing run function.
If F7.42 timing function is active, the inverter starts as the timer starts, when the set timing
run time is reached, the inverter automatically shut down, at the same time the multi-function DO
will output ON signal.
Every time the inverter starts, the timer will time from 0, the remaining time can be viewed
by d0.20. The timing run time is set by F7.43, F7.44 in minute.

When current running time reaches this time, the inverter multi-function digital DO will
output"Current Running Time Arrival "ON signal.
