Adjustment Procedure
（Ver.2.04 and above)
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
