1. Set up IPM motor
Pr05-33=2
2. Set up motor parameter according to the motor Nameplate
Pr01-01 Output Frequency of Motor 1 base frequency and motor rated frequency
Pr01-02 Output Voltage of Motor 1 base frequency and motor rated frequency
Pr05-34 Full-load current of Permanent Magnet Motor
Pr05-35 Rated Power of Permanent Magnet Motor
Pr05-36 Rated speed of Permanent Magnet Motor
Pr05-37 Pole number of Permanent Magnet Motor
3. Execute Auto-tuning
Set upPr05-00=13 for IPM motor tuning and press Run(static-tuning). When the tuning
is done, the following parameters will be obtained.
Pr05-39 Stator Resistance of PM Motor
Pr05-40 Permanent Magnet Motor Ld
Pr05-41 Permanent Magnet Motor Lq
4. Set up control mode: Pr00-10=0 velocity mode, Pr00-11=7 IPM sensor-less
5. Turn OFF the power and power ON again.
6. Modify the ASR Kp and Ki according to system need.
