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.
Timing function selection
Timing run time selection
Analog input range 100% corresponds to F7.44
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.
Current running arrival time.
When current running time reaches this time, the inverter multi-function digital DO will
output"Current Running Time Arrival "ON signal.

lower limit
AI1 input voltage
protection upper limit
When analog AI1 input is greater than F7.51, or when AI1 input is less than F7.50, the
inverter multi-functional DO will output "AI1 input overrun"signal, so as to indicate whether the
AI1 input voltage is within the set range or not.
