1Only for the unloaded motor, auto measure the angle between magnetic field and PG origin (08-09)

2For PM motor parameters

3Auto measure the angle between magnetic field and PG origin (08-09)

For setting 1: It can auto measure the angle between magnetic field and PG origin. Please notice the following items when measuring:

1.Please unload before tuning.

2.If brake is controlled by drive, the drive will act by the normal operation to finish tuning after wiring and setting brake control parameters.

3.If brake is controlled by the host controller, it needs to make sure that brake is in release

state before tuning.

For setting 2: Starting auto tuning by pressing RUN key and it will write the measure value into Pr.08-05 to Pr.08-07 (Rs, Lq).

The steps to AUTO-Tuning are: (Dynamic measure)

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

2.Motor: Fill in Pr.08-01, Pr.08-02, Pr.08-03 and Pr.08-04 with correct values. Refer to motor capacity to set accel./decel. time.

3.When Pr.08-00 is set to 2, the AC motor drive will execute auto-tuning immediately after receiving a “RUN” command. (NOTE: the motor will run! The shaft needs to be locked with external force.)

4.After executing, please check if all values are filled in Pr.08-05 and Pr.08-07.

For setting 3: It can auto measure the angle between magnetic field and PG origin. Please notice the following items when measuring:

1.It can be loaded motor or unloaded motor before tuning.

2.If brake is controlled by drive, the drive will act by the normal operation to finish tuning after wiring and setting brake control parameters.

3.If brake is controlled by the host controller, it needs to make sure that brake is in release state before tuning.
