T1-03: Motor Rated Voltage (T1-01 = 0 or 3)
Used to set the motor rated voltage according to the motor nameplate value. If the motor is used above its base speed, enter
the voltage at base speed here.
For higher tuning precision and better control performance, enter the motor no-load voltage here if known. The motor no-load
voltage is referred as to the voltage needed to operate the motor under no-load condition at its rated speed. Refer to the motor
data sheet.

T1-04: Motor Rated Current
Used to set the motor rated current according to the motor nameplate value. For optimal performance in OLV, the motor rated

T1-05: Motor Rated Frequency (T1-01 = 0 or 3)
Used to set the motor rated frequency according to the motor nameplate value. If a motor with an extended speed range is used
or the motor is used in the field weakening area, enter the base frequency here.
For higher tuning precision and better control performance, enter the motor no-load frequency here if known. The “no-load

T1-11: Motor Iron Loss (T1-01 = 3)
Provides iron loss information for determining the Energy Saving coefficient. If E2-10 has been changed and the power has
been cycled, the value set to E2-10 will appear as the default in T1-11. If the value of T1-02 is not changed during Auto-
Tuning data input, the drive will select a value that is typical for the motor power entered to T1-02.
