 Basic motor parameters adjustment
1. Parameter reset:
Reset Pr.00-02=9 (50Hz) or 10 (60Hz) to the default value.
2. Select IPM motor type:
Pr.05-33=2 (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.05-33 PM motor type (IPM or SPM)
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)
AUE3 (144) Auto-tuning error 3 (No-load current I
0
measuring error)
AUE4 (148)
Auto-tuning error 4 (Leakage inductance Lsigma measuring
error)
5. Set control mode
Control mode for the drive: Pr. 00-10 = 0: Speed mode
Control mode for the motor: Pr. 00-11 = 7: Interior PM FOC Sensorless
6. After auto-tuning, cycle the power.
7. Measure the initial magnetic pole angle of PM
When Pr.00-11=7 PM FOC Sensoreless mode, the initial magnetic pole angle detection
method is high frequency injection.
