4.5 Auto-Tuning
■ T1-03: Motor Rated Voltage
Sets the motor rated voltage according to the motor nameplate value. Enter the motor voltage at 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% o f the rated
voltage printed on the motor nameplate. This may increase the output current and reduce the overload margin.

■ 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%

■ T1-05: Motor Base Frequency
Sets the motor rated frequency according to the motor nameplate value. If a motor with an extended speed range is used
or if the motor is used in the field weakening area, enter the maximum frequency to E1-04 (E3-04 for motor 2) after
Auto-Tuning is complete.
