4.5 Auto-Tuning
◆ Parameter Settings during Induction Motor Auto-Tuning: T1
The T1-
parameters are used to set the Auto-Tuning input data for induction motor tuning.
Note: For motors operating in the field weakening range, first perform the Auto-Tuning with the base data. After Auto-Tuning is
complete, change E1-04, Maximum Output Frequency, to the desired value.

■
T1-03: Motor Rated Voltage
Sets the motor rated voltage according to the motor nameplate value. Enter the voltage base speed here if the motor is
operating above base speed.
Enter the voltage needed to operate the motor under no-load conditions at rated speed to T1-03 for better control precision
around rated speed when using a vector control mode. The no-load voltage can usually be found in the motor test report
available from the manufacturer. If the motor test report is not available, enter approximately 90% of the rated voltage
printed on the motor nameplate. This may increase the output current and reduce the overload margin.

<1> Values shown are specific to 200 V class drives. Double value for 400 V class drives.
■
T1-04: Motor Rated Current
Sets the motor rated current according to the motor nameplate value. Set the motor rated current between 50% and 100%
of the drive rated current for optimal performance in OLV or CLV. Enter the current at the motor base speed.
