Adjustment procedure
1. Sep up PM motor control
Pr05-33=1 or 2
2. Set up motor parameter according to the nameplate on the motor
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
PM motor inertia (E-4 kg-m2) Pr05-38 (power, current and speed of motor auto calculates
to get this value)
PM motor Ke (V/1000rpm) Pr05-43 (power, current and speed of motor auto calculates to
get this value)
