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 current should be between 50 and 100% of the drive rating. Enter the current at the motor base speed.
■
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.
■
T1-06: Number of Motor Poles (T1-01 = 0 or 3)
Used to set the number of motor poles according to the motor nameplate value.
■
T1-07: Motor Rated Speed (T1-01 = 0 or 3)
Used to set the motor rated speed 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 speed at base frequency here.
■
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.
