Delta Electronics VFD-VL manual Step

Chapter 3 Operation and Start Up

NOTE 1: It doesn’t need to release the brake in this auto tuning operation. Please make sure that the electromagnetic valve is ON when it is used between the AC motor drive and motor. The warning message “Auto tuning” will be displayed on the digital keypad during tuning until it is finished. Then, the measure result will be saved into Pr.08-05 and Pr.08-07. (Pr.08-05 is Rs of Motor and Pr.08-07 is Lq of Motor)

NOTE 2: The auto tuning of the IM motor can also be dynamic measure.

NOTE 3: It doesn’t need to release the brake for the static measure.

3.3.2.3 Step 3

Encoder settings

„Selection of speed feedback cards

Please refer to appendix B.8 for details. Delta provides 4 PG cards for user to select by their application, including EMVL-PGABL, EMVL-PGABO, EMVL-PGH01 and EMVL- PGS01.

PM motor

It can execute “RUN” by keypad or digital terminals:

„Using digital keypad: setting Pr.08-00=1 and press RUN to execute “auto measure the angle between magnetic field and PG origin”.

Please notice that if the electromagnetic valve and brake is not controlled by the AC motor drive, please release it by manual.

„Using external terminals: Pr.00-14=3, Pr.00-15=1 (refer to step 1). Please use “inspection” function to execute “auto measure the angle between magnetic field and PG origin”.

For the IM motor, it doesn’t need to detect the position of the electromagnetic pole, this function (auto measure the Angle between magnetic field and PG origin) doesn’t have to be executed.

Measure the angle between magnetic field and PG origin: Pr.08-00=1 or 3

Pr.08-00

Motor Auto tuning

0:No function

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

2:For PM motor parameters

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

NOTE 1: It is recommended to set Pr.08-00 to 1 (unloaded motor) for the accurate calculation. If it needs to execute this function with loaded motor, please balance the carriage before execution.

NOTE 2: if it doesn’t allow balancing the carriage in the measured environment, it can set Pr.08-00=3 for executing this function. It can execute this function with loaded motor by setting Pr.08-00=3. It will have a difference of 15~30o by the different encoder type.

NOTE3: It will display the warning message “Auto tuning” on the digital keypad during measuring until the measure is finished. Then, the result will be saved into Pr.08-09.
