Chapter5.Function parameter
43
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.
Fault DO action selection
during 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
Automatic fault reset
interval
It is the waiting time from the inverter fault alarm to automatic fault reset.
Load drop protection
selection
Load drop detection
level
0.0% to 100.0% (rated motor
current)
If the load drop protection function is active, when the inverter output current is less
than the load drop detection level (F8.31)and the duration is longer than the load drop
detection time(F8.32), the inverter output frequency is automatically reduced to 7% of the
rated frequency. During the load drop protection, if the load recovers, the inverter
automatically resumes to the set frequency to run.
