How to solve above problems:

Reset the V/F curved shaped and the torque data;

Check the power source;

Adjust the working load or choose another inverter which is suitable for the
capacity of electric motor;

When low speed of motor and long working time is needed, choose the
exclusive frequency conversation electric motor.


When the electric motor is initiated, after a short stop;

V/F curved is set improperly or the torque data is too much;
How to solve above problems:

Change the inverter whose capacity is matching;

Prolong the accelerate time;
