In the case of too large difference between the actual power ofthe motor and that of adaptable motor for inverter, the inverter’s control performance willdecrease remarkably.F800=0, parameter tuning is invalid. But it is still necessary to set the parametersF801~F803,F805 and F810 correctly according to those indicated on the nameplate of themotor.After being powered on, it will use default parameters of the motor (see the values of F806-F809) according to the motor power set in F801. This value is only a reference value in view ofY series 4-pole asynchronous motor.F800=1, rotating tuning.In order to ensure dynamic control performance of the inverter, select “rotating tuning” afterensuring that the motor is disconnected from the load. Set F801-805 and F810 correctly prior torunning the rotating autotune.Press the “I” key on the keypad to display “TEST”, and the inverter will tune the motor’sparameter in two stages. After that, the motor will accelerate according to acceleration time setat F114 and maintain it for a certain period. The motor will then decelerate to 0 according tothe time set at F115. After auto-checking is completed, relevant parameters of the motor will bestored in function codes F806~F809, and F800 will be automatically set back to 0.F800=2, stationary tuning.In some cases it may be impossible to disconnect the motor from the load.Press the “I” key, and the inverter will display “TEST”, and the inverter will tune the motor‘sparameter in two stages. The motor’s stator resistance, rotor resistance and leakageinductance will be stored in F806-F809 automatically (the motor’s mutual inductance usesdefault value generated according to the power), and F800 will be automatically set back to 0.The user may also calculate and input the motor’s mutual inductance value manuallyaccording to actual motor data.
