corresponds the number of following adjustment explanations)
I. IPM Sensoress FOC Mode Motor Parameter
1. Parameter Reset
Pr.00-02=10
2. Pr.05-33 Motor type=2 (IPM)
FOC Sensorless control
( For IPM motor)
3. Motor Parameter Setting

Pr.05-34 Full-load Current
Pr.05-35 Rated Power
Pr.05-36 Rated Rotor Speed
Pr.05-37 Motor Poles
4. Motor Parameter Auto-Tuning
Pr.05-00=5
（PM parameters dynamic measuring）
Or Pr.05-00=13
（PM parameters static measuring）
Press 'RUN’
PM FOC Sensorless
Adjustment Procedure
Motor auto-tuning
successful?
1. AUE auto-tuning error
2. Measured resistance,
inductance or back
EMF error
Check Motor Parameters
Pr.05-39 Rs stator resistance
Pr.05-40 Permanent magnet
motor Ld
Pr.05-41 Permanent magnet
motor Lq
Pr.05-43 Ke parameter
6. Re-power after Power Off
YES
7. Initial Angle Detection
Pr.10-53 angle detection
2：High frequency injection
PM FOC Sensorless Control
The initial angle is only
detected by “2” high
frequency injection, and cannot
be changed.
NO
8. No-load
Running
5. Set Control Mode
Pr.00-10=0 Speed mode
Pr.00-11=7 FOC Sensorless control
