When analog AI1 input is greater than F7.51, or when AI1 input is less than F7.50, the
inverter multi-functional DO will output "AI1 input overrun"signal, so as to indicate whether the
AI1 input voltage is within the set range or not.

When the inverter output current reaches the set current stall protection current (F8.01), the
inverter reduces the output frequency in the acceleration or constant speed operation, while the
slow down speed, until the current is less than the current (F8.01).
Over-current stall gain is used for adjusting inhibition over-current capability during
ac/deceleration. The greater this value, the stronger inhibition over-current capability Under the
premise that the over-current does not occur, the best is the smaller gain setting.
For the small inertia load, the over-current stall gain should be small, otherwise which cause
the slower system dynamic response. For the big inertia load, the over-current stall gain should be
large, otherwise the poor inhibitory effect may cause over-current fault.
When the over-current stall gain is set to 0, the over-current stall function will be canceled.

F8.02 = 0: no motor overload protection function, there may be the risk of damage to the
motor due to overheating, it is recommended that the thermal relay is installed between the inverter
and the motor;
F8.02 = 1: the inverter will determine whether the motor is overloaded or not according to the
inverse time curve of motor overload protection. Inverse time curve of motor overload protection:
220% x (F8.03) x rated motor current, if this lasts for 1 second, the alarm of motor will be
prompted overload fault; 150% x (F8.03) × rated motor current, if this lasts for 60 seconds, the
