1 Only for the unloaded motor, auto measure the angle between magnetic

pole and PG origin (Pr. 08-09)

2 For PM parameters

3 Auto measure the angle between magnetic pole and PG origin (Pr. 08-09)

 For setting=1: It can auto measure the angle between magnetic pole 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, 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 brushless DC 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 pole 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.

4. Please ensure Encoder Input Type Setting (Pr.10-02) is accurate. A false setting would

affect the position detection of magnetic pole and cause inaccurate angle between

Magnetic Pole and PG Origin (Pr.08-09).
