Motor Rated Power
Sets the rated output power (kW) of the motor.
Determined by o2-04
(0.00 - 590.0 kW)
Note:
Capacities 300 kW and less are set in units of 0.01 kW. Capacities above 300 kW are set in units of 0.1 kW.

T1-03: Motor Rated Voltage
No.
(Hex.)
Name Description
Default
(Range)
T1-03
(0703)
Motor Rated Voltage
Sets the rated voltage (V) of the motor. Enter the base speed voltage for constant output motors.
Determined by o2-04
(200 V Class: 0.0 - 255.5 V,
400 V Class: 0.0 - 511.0 V)
If auto tuning is carried out with respect to a drive dedicated motor or a special motor for use with vector control,
the voltage or frequency derived as the result of the tuning will often be lower than that of a general-purpose
motor. For this reason, always compare the data from the nameplate or test report with the results measured by the
auto tuning and check for discrepancies. 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. 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. Current will increase
if the input power supply voltage is low. For this reason, confirm the main power supply capacity and molded-
case circuit breaker for the drive.

T1-04: Motor Rated Current
No.
(Hex.)
Name Description
Default
(Range)
T1-04
(0704)
Motor Rated Current
Sets the rated current (A) of the motor.
Determined by o2-04
(10% to 200% of the drive
rated current)
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.)
Name Description
Default
(Range)
T1-05
(0705)
Motor Base Frequency
Sets the base frequency (Hz) of the motor.
50.0 Hz
(0.0 - 590.0 Hz)
When Auto-Tuning is carried out, the value of T1-05 is set to E1-04 [Maximum Output Frequency] . However, E1-
04 is set to 40 Hz if T1-05 is set to a value less than 40 Hz. If you operate the drive at a speed that is higher than
the base frequency, set E1-04 ( E3-04 for motor 2, E7-04 for motor 3) to the maximum output frequency after you
complete Auto-Tuning.
