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).
Overcurrent stall gain is used for adjusting inhibition overcurrent capability during
ac/deceleration. The greater this value, the stronger inhibition overcurrent capability Under the
premise that the overcurrent does not occur, the best is the smaller gain setting.
For the small inertia load, the overcurrent stall gain should be small, otherwise which cause
the slower system dynamic response. For the big inertia load, the overcurrent stall gain should be
large, otherwise the poor inhibitory effect may cause overcurrent fault.
When the overcurrent stall gain is set to 0, the overcurrent 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
alarm of motor overload will be prompted.
User shall correctly set the value of F8.03 according to the Actual motor overload capacity, if
the value is set to too large , which may easily lead to motor overheating and damage while the
inverter will not alarm!

Motor overload pre-alarm coefficient

☆
This function is used in the front of motor overload fault protection, and sends a pre-alarm
signal to the control system by DO. The warning coefficient is used to determine the extent of pre-
alarm prior to motor overload protection. The higher the value, the smaller the extent of pre-alarm
