05 Motor Parameters This parameter can be set during operation.
Motor Auto Tuning
Factory Setting: 0
Settings 0: No function
1: Rolling test for induction motor(IM) (Rs, Rr, Lm, Lx, no-load current)
[motor running]
2: Static test for induction motor [motor not running]
5: Dynamic test for PM (SPM) motor [motor running]
13: Static test for PM(IPM) motor
Induction Motor
This parameter can conduct motor parameters auto test. When setting as 1, motor will roll for
more than one round.
Press 【Run】to begin auto tuning when the setting is done. The measured value will be written
into motor 1 (Pr.05-05 ~05-09, Rs, Rr, Lm, Lx, no-load current) and motor 2 (Pr.05-17 to Pr.05-21)
automatically.
To begin AUTO-Tuning in rolling test:
1. Make sure that all the parameters are set to factory settings (Pr00-02=9 or 10) 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. Please set motor related parameters according to motor nameplate.

4. Set Pr.05-00=1 and press【Run】, the drive will begin auto-tuning. Please be aware of the
motor that it starts spinning as【Run】 is pressed.
5. When auto-tuning is completed, please check if the measured values are written into motor
1 (Pr.05-05 ~05-09) and motor 2 (Pr.05-17 ~05-21) automatically.

※ If Pr.05-00 is set to 2 (static test), user needs to input the no-load current value of motor
into Pr.05-05 for motor 1/Pr.05-17 for motor 2.
