When fault self-recovery restart uptime over an hour later, it will restore the original
setting of automatic fault reset.

It is the waiting time from the inverter fault alarm to automatic fault reset.

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.

large speed
deviation
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.
