This parameter automatically measures the motor’s characteristics and enters the values
into Pr.05-02, Pr.05-06~09, Pr.05-12, Pr.05-16~19, respectively.
Note 1. The Torque/Vector control mode is not intended for use with multiple motors connected
to one AC drive.
Note 2. If two motors will be connected to one drive and both must be auto tuned, it is
necessary to set a multi-function input terminal to switch between Motors 1 and 2.
This will enable the drive to enter the calculated values into the correct parameter
positions.
Note 3. When using the Auto tune feature with a loaded motor, please set Pr05-00 = 2 or 3. A
setting of 2 or 3 is a “Static tune” and no movement of the motor is necessary to
calculate the motor characteristics. If a Static tune is desired, please make sure to
input the correct No-Load and Full-Load current before conducting the Auto Tuning
feature.
Motor Auto Tuning Procedure:
1. Make sure all the parameter settings are at the factory settings and all power wiring is
correct.
2. Remove any load on the motor before proceeding with the auto tuning (Nothing should be
connected to the motor shaft).
3. Enter the motor rated voltage in Pr. 01-02 and motor rated frequency in Pr. 01-01.
4. Set Pr. 05-00 = 1, 2, or 3, then press the “RUN” key on the keypad to execute the motor
auto-tuning operation (Caution: the motor will begin to turn if Pr.05-00 is set to 1). The
execution time is about 2 minutes. (The greater the horsepower of the motor, the longer the
acceleration/deceleration time should be set).
5. After the auto tuning procedure is complete, verify the parameters (Pr.05-02, Pr.05-06~09,
Pr.05-12 and Pr.05-16~19) have been updated. If not, set Pr.05-00 = 1 to 3 and press the
“RUN” key again.
