Starting auto tuning by pressing RUN key and it will write the measure value into Pr.05-05 to

Pr.05-09 (Rs, Rr, Lm, Lx, no-load current).

The steps to AUTO-Tuning are: (when setting to 1)

1.Make sure that all the parameters are set to factory settings and the motor wiring is correct.

2.Make sure the motor has no-load before executing auto-tuning and the shaft is not connected to any belt or gear motor. It is recommended to set to 2 if the motor can’t separate from the load.

3.Fill in Pr.01-02, Pr.01-01, Pr.05-01, Pr.05-02, Pr.05-03 and Pr.05-04 with correct values. Refer to motor capacity to set accel./decel. time.

4.When Pr.05-00 is set to 1, the AC motor drive will execute auto-tuning immediately after receiving a “RUN” command. (NOTE: the motor will run!)

5.After executing, please check if all values are filled in Pr.05-05 to Pr.05-09.

Equivalent circuit for VFD -VL ser ie s

 

If Pr.05-00 is set to 2, it needs to input Pr.05-05.

NOTE

1.In torque/vector control mode, it is not recommended to have motors run in parallel.

2.It is not recommended to use torque/vector control mode if motor rated power exceeds the rated power of the AC motor drive.

3.The no-load current is usually 20~50% X rated current.
