T1-03 Motor Rated Voltage
(0703)
If you do Auto-Tuning on a drive-dedicated motor or a specialized motor for vector control, the voltage or frequency
can be lower than that of a general-purpose motor. Always compare the data from the nameplate or test report with
the Auto-Tuning results and check for differences. Enter the voltage necessary to operate the motor in no-load
conditions at rated speed for better control precision around rated speed. If the motor test report or the motor
nameplate is not available, enter approximately 90% of the motor rated voltage.
If the drive input power supply voltage is low, enter approximately 90% of the input voltage. When the input power
supply voltage is low, the current will increase. Make sure that the main power supply capacity is correct and use a
molded-case circuit breaker for the drive.

T1-04 Motor Rated Current
(0704)
Set the motor rated current between 50% and 100% of the drive rated current for the best performance. Enter the
current at the motor base speed.

T1-05: Motor Base Frequency
No.

(Hex.)
T1-05 Motor Base Frequency
(0705)
When Auto-Tuning is carried out, the value of T1-05 is set to E1-04 [Maximum Output Frequency]. If T1-05 < 40 Hz,
E1-04 = 40 Hz. If you operate the drive at a speed that is higher than the base frequency, or if you operate in the field
weakening range, set E1-04 (E3-04 for motor 2) to the maximum output frequency after you complete Auto-Tuning.
