Valid 1
You can detect whether the motor is shorted to ground when the inverter is powered on.
If this function is active, the inverter's UVW terminal will output voltage after power-on for a
while.
F8.10 Number of automatic fault reset 0~32767 0
☆
When the inverter selects automatic fault reset, it is used to set the number of times of
automatic fault reset. If the set number of times is exceeded, the inverter remains a failed state.
When set F8.10 (number of automatic fault reset) ≥ 1, inverter will run automatically when
repower after instantaneous power-off.
When fault self-recovery restart uptime over an hour later, it will restore the original setting
of automatic fault reset.

If the inverter automatic fault reset function is set, F8.10 can be used to set whether DO
action is active or not during the automatic fault reset
F8.12 Automatic fault reset interval 0.1s~100.0s 1.0s
☆
It is the waiting time from the inverter fault alarm to automatic fault reset.

%
☆
F8.14 Overspeed detection time 0.0s~60.0s 1.0s
☆
This feature is only available when the inverter runs with speed sensor vector control.
When the inverter detects that the actual motor speed exceeds the set frequency, and the excess is
greater than the overspeed detection value(F8.13), and the duration is greater than the overspeed
detection time(F8.14) the inverter will alarm fault ID Err.43, and troubleshoots according to the
protection action.
F8.15
Detection value for too large speed
deviation
0.0%~50.0%(maximum frequency) 20.0%
☆
F8.16
Detection time for too large speed
deviation
0.0s~60.0s 5.0s
☆
This feature is only available when the inverter runs with speed sensor vector control.
When the inverter detects that the actual motor speed is different from the set frequency, and
the deviation is greater than the detection value for too large speed deviation(F8.15), and the
duration is greater than the detection time for too large speed deviation(F8.16), the inverter will
alarm fault ID Err.42, and troubleshoots according to the protection action.
If the detection time for too large speed deviation is 0.0s, the detection for too large speed
deviation is canceled.
