 Basic Motor Parameters Adjustment
1. Parameter reset
Reset Pr.00-02=10 to the default value.
2. Select PM motor type
Pr.05-33 = 1 or 2 (SPM or IPM)
3. Motor nameplate parameter setting
Parameter Description
Pr.01-01 Output frequency of motor 1 (Hz)
Pr.01-02 Output voltage of motor 1 (V
AC
)
Pr.05-34 Full-load current for PM (A)
Pr.05-35 Rated power for PM (kW)
Pr.05-36 Rated speed for PM (rpm)
Pr.05-37 Pole number for PM (poles)
Pr.05-38 System inertia for PM (kg-cm
2
)
4. Motor parameter auto-tuning:
Set Pr.05-00=5 (rolling auto-tuning for PM) or 13 (static auto-tuning for PM), press RUN to
finish the motor parameter auto-tuning, then you will get the following parameters:
Parameter Description
Pr.05-39
Stator resistance for a permanent magnet motor (Ω)
Pr.05-40 Permanent magnet motor Ld (mH)
Pr.05-41 Permanent magnet motor Lq (mH)
Pr.05-43
Ke parameter of a permanent magnet motor (V
phase
，
rms
/ krpm)
(When Pr.05-00=5, the Ke parameter is measured based on the actual
motor rotation.)
(When Pr.05-00=13, the Ke parameter is automatically calculated based
on the motor power, current and rotor speed.)
If an auto-tuning error (AUE) occurs, refer to Section 14 “Fault Codes and Descriptions” for
further treatment.
AUE Error (code) Description
AUE (40) Auto-tuning error
AUE1 (142) Auto-tuning error 1 (No feedback current error)
AUE2 (143) Auto-tuning error 2 (Motor phase loss error)
5. Control mode setting
Pr.00-10=0, speed mode
Pr.00-11=6, PM Sensorless control mode
6. After motor auto-tuning, cycle the power.
7. Measure the initial magnetic pole angle of PM
Set Pr.10-53 PM initial rotor position detection method
0: Disable
1: Internal 1/4 rated current attracting the rotor to zero degrees
2: High frequency injection
3: Pulse injection
(Set to 2 for IPM; set to 3 for SPM. If these settings cause problems, then set the parameter to
1.)
