Chapter 3 Operation and Start Up

„Motor Auto-tuning: When the Source of the Operation Command is set to digital keypad (Pr.00-15=2, refer to step 1) and setting Pr.05-00=2

Pr.05-00

Motor Auto tuning

0:No function

1:Rolling test (Rs, Rr, Lm, Lx, no-load current)

2:Static Test

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. When Pr.05-00 is set to 2, no-load current of motor must be entered into Pr.05-05. 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.05-06~Pr.05-09.

NOTE 2: It needs to finish motor auto tuning before measuring the angle between magnetic field and PG origin.
