Basic motor parameters adjustment
1. Parameter reset:
Reset Pr.00-02 = 9 (50 Hz) or 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:
Set Pr.05-00 = 5 (rolling auto-tuning for PM, with no load) 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 Chapter 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. 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
6. Re-power ON after power OFF.
7. Measure the initial magnetic pole angle of PM
Set Pr.10-53 PM initial rotor position detection method
0: Disabled
1: Using I/F current command (Pr.10-31) to attract the rotor to zero degrees
2: High frequency injection
3: Pulse injection
* For IPM, the setting value is suggested to be 2; for SPM, the setting value is suggested to
be 3. You can choose the setting 1 if the result is not good of setting as 2 or 3.
