should be large, otherwise the poor inhibitory effect may cause overvoltage fault.
When the overvoltage stall gain is set to 0, the overvoltage stall function will be canceled.
Output phase loss
protection selection
Select whether the output phase loss protection is done or not.
Power-on short circuit to ground
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.
Number of automatic fault reset
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.
