value should be large. Otherwise, the suppressing result will be poor, and
over voltage fault may be caused.
Over voltage stall protection voltage: It selects the protection point for over
voltage stall function. When the value is exceeded, the inverter starts to
execute the over voltage stall protection function.

Over current stall: When the output current of the inverter reaches setup
over current stall protection current (FB-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 (FB006). Please refer to Fig.6-23 for details.
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.
