Motor parameters adjustment
1. Parameter reset:
Reset Pr.00-02 = 10 to the default value.
2. Select motor type:
Pr.05-33 = 1 or 2 (SPM or IPM)
3. Motor nameplate parameter setting:
Parameter Description
Pr.01-01
Motor 1 Rated / Base Frequency (Hz)
Pr.01-02
Motor 1 Rated / Base Output 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 motor poles (poles)
Pr.05-38 System inertia for PM (kg-cm
2
)
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
AUE 1 (142) Auto-tuning error 1 (no feedback current error)
AUE 2 (143) Auto-tuning error 2 (motor phase loss error)
5. Set control mode
Set Pr.00-11 = 6 PM Sensorless FOC control mode
6. After auto-tuning, 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: Force attracting 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.
