Over voltage stall
：
When the output voltage of the inverter reaches setup of over voltage stall
protection voltage (F9.04), if the inverter is running with acceleration speed, it will stop acceleration. When
the inverter is running with constant speed, it will reduce the output frequency. When the inverter is running
with deceleration speed, it will stop deceleration and the operating frequency will not recover normally till
the current is less than the current stall protection current (F9.04).
Over voltage stall protection voltage
：
It selects the protection point for over current stall function.
When the value is exceeded, the inverter starts to execute the over voltage stall protection function. This
value is relative to the percentage of rated voltage of the motor.
Over-voltage stall gain
：
It adjusts the inverter’s capacity in suppressing the voltage stall. The bigger
the value is, the stronger the capacity is. For the load with small inertia, the value should be small.
Otherwise, the dynamic response of the system would be slow. For the load with large inertia, the value
should be large. Otherwise, the suppressing result will be poor, and over voltage fault may be caused.
When the voltage stall gain is set to 0, the inverter starts to execute the over voltage stall protection
function.

Over current stall
：
When the output current of the inverter reaches setup of over current stall
protection current (F9.06), if the inverter is running with acceleration speed, it will stop acceleration. When
the inverter is running with constant speed, it will reduce the output frequency. When the inverter is running
with deceleration speed, it will stop deceleration and the operating frequency will not recover normally till
the current is less than the current stall protection current (F9.06).
Over current stall protection current
：
It selects the protection point for over current stall function.
When the value is exceeded, the inverter starts to execute the over current stall protection function. This
value is relative to the percentage of rated current of the motor.
Over current stall gain
：
It adjusts the inverter’s capacity in suppressing the over current stall. The
bigger the value is, the stronger the capacity is. the stronger the capacity is. For the load with small inertia,
the value should be small. Otherwise, the dynamic response of the system would be slow. For the load with
large inertia, the value should be large. Otherwise, the suppressing result will be poor, and over currentfault
may be caused.
When the current stall gain is set to 0, the inverter starts to execute the over voltage stall protection
function.
F9.07 Ground short circuit protection

1
☆
Valid
1
It determines whether the motor has ground short circuit fault upon power-on. If this function is valid,
the inverter UVW end will output voltage within the period of time after power-on.
F9.09
Fault auto reset times

0
☆
When the inverter selects fault auto reset, it is used to set the times of auto reset. If this value is
exceeded, the inverter will perform fault protection.
