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 frequency” refers to the frequency needed to operate the motor under no-load condition at its rated speed. Refer to
the motor data sheet.

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.
