Section V. Parameter Function Table
arrival setup
When the accumulated running time (P7.09) reaches this set running time, the digital output terminal
DO outputs the ON signal of running time arrival.
P8.18
Start protection selection
Invalid 0
0
☆
Valid
1
This parameter is used to improve the safety protection coefficient.
If it is set to 1, it has two functions
：
1.If running command is valid upon power on (E.g
：
Closed-state before terminal running command
power on), inverter will not respond to the running command. Users should first cancel running command,
after running command coming into valid again, the inverter then responds.
2.If running command is valid upon inverter fault reset, inverter will not respond to the running
command. Running protection status can be eliminated after cancelling the running command.
This can prevent the dangers caused by the automatic running of the motor under unexpected
condition.

When the running frequency is higher than the frequency detection value,multi-function terminal DO
output ON signal.On the contrary,ON signal is canceled if running frequency is less than a certain value of
the detection valule.
It is used to set the detection value of the output frequency and the hysteresis value upon release of
the output action.P8.20 is the hysteresis frequency percentage relativing to P8.19 frequency detection
value.
