F8-00=1: no motor overload protection function, there may be a motor overheating damage risk,
suggest adding thermal relay between inverter and motor.
F8-00=1: inverter according to the motor overload protection inverse time curve detemine whether the
motor overload at this moment.
Inverse time curves of the motor overload protection are as follows: 220% X (F8-01) X rated motor
current, last 1 minute alarm motor overload fault; 150% X (F8-01) X rated motor current, last 60
minutes alarm motor overload.
User needs according to the actural overload capacity of motor, set up the F8-01 value correctly, if set
the parameter is too big easy to cause the damage of motor overheating, and inverter is not alarm.

○
This function is used to in the front of the motor overload fault protection, through the DO give a
warning signal to control system. The warning coefficient used to detemine how much to warning
before the motor overload protection. The greater the value, the smaller the warning advance.
When the inverter output current cumulants is greater than the product of overload inverse time curve
with F8-02, inverter multi-function digital DO output the “motor overload warning” ON signal.

In the process of frequency converter to slow down, when DC bus voltage more than the overvoltage
stall protection voltage, frequency converter to stop deceleration to keep on the current running
frequency, after waiting for bus voltage drops to continue to deceleration.
Overvoltage stall gain, used to adjust in the process of deceleration, inverter overvoltage control
capability. The biger the value is, the greater the inhibition of overvoltage ability is. On the premise of
not occur overvoltage, the gain settings as small as possible.
For small inertia load, the gain of the overvoltage stall is small is better, otherwise the system dynamic
