Adjustment procedure
1. Parameter reset
Pr00-02=10 or 9
(By doing this, avoid other parameters which are not related to influence motor)
2. Set up motor parameter according to the nameplate on the motor
Pr01-01 Output Frequency of Motor 1
（
base frequency and motor rated frequency
）
Pr01-02 Output Voltage of Motor 1
（
base frequency and motor rated frequency
）
Pr05-01 Full-lad current
Pr05-02 Rated power
Pr05-03 Rated speed
Pr05-04 Poles
3. Press “RUN” to start auto tuning of IM magnetic flux curve dynamic test for Pr05-00=1 or 6
(motor is running). Make sure the motor executes auto tuning under break-away load
condition. And check if there are motor parameters after auto tuning.
Pr05-06 Rs Stator resistance
Pr05-07 Rr Rotor resistance
Pr05-08 Lm Magnetizing inductance
Pr05-09 Lx Stator inductance
4. Execute motor inertia estimation (optional). Press “RUN” to start it after finishing the setting
of the parameters mentioned below.
Pr00-10=2 Torque mode
Pr00-13=2 TQC sensorless
Pr05-00=12 FOC sensorless inertia estimation (motor is running)
 After inertia estimation is finished, check Pr11-01 whether the value is reasonable or not
according to the base value table below. (Unit: 0.001kg-m^2)

5. Execute running with IM sensorless FOC mode, set up the following parameter,
Pr00-10 = 0, set as speed mode
Pr00-11 = 5, set as FOC sensorless mode
Pr11-00-bit0 =1, ASR gain auto tuning
Press “RUN” and start the
test with no-load
. Speed up the motor to the rated speed,
and then lower the speed to stop, check the motor runs smoothly or not.
