Basic Motor Parameters Adjustment
1. Parameter reset:
Reset Pr.00-02=10 (60 Hz) to the default value.
2. Select PM motor type:
Pr.05-33=1 (SPM) or 2 (IPM)
3. Motor nameplate parameter setting:
Parameter Description
Pr.01-01 Rated frequency (Hz)
Pr.01-02 Rated voltage (V
AC
)
Pr.05-34 Rated current (A)
Pr.05-35 Rated power (kW)
Pr.05-36 Rated rotor speed (rpm)
Pr.05-37 Number of poles for the motor (poles)
4. PM parameter auto-tuning:
5. Set Pr.05-00=5 (Rolling auto-tuning for PM) or 13 (Static auto-tuning for PM) and press “RUN”
key to finish motor 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)
6. Set control mode
Control mode for the drive: Pr.00-10 = 0: Speed mode
Control mode for the motor: Pr.00-11 = 2: PM SVC mode
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.)
