T1: Induction Motor Auto-Tuning
No. Name Description Setting
T1-01
<4> Default setting value varies by the drive model (o2-04).
<5> Default setting is determined by the control mode (A1-02).
<9> Values shown here are for 200 V class drives. Double the value when using a 400 V class drive. Multiply value by 2.875 for 600 V class drives.
<10> The display resolution depends on the rated output power of the drive. Models CIMR-LU20008 to 20033, 40005 to 40018, and
50003 to 50013 display values in 0.01 A units, while models CIMR-LU20047 to 20415, 40024 to 40605, and 50017 to 50200
display values in 0.1 A units.
<18> The variety of Auto-Tuning methods depends on the control mode setting. V/f Control allows T1-01 to be set to 2 or 3, while vector control
modes (OLV and CLV) allow T1-01 to be set to 0 through 4.

Default: 0
<5>
Min: 0
Max: 4 <18>
T1-02 Motor Rated Power
Sets the motor rated power as specified on the motor nameplate.
Note: Use the following formula to convert horsepower into kilowatts: kW = HP ×
0.746.
Default: <4>
Min: 0.00 kW
Max: 650.00 kW
T1-03 Motor Rated Voltage Sets the motor rated voltage as specified on the motor nameplate.
Default: 200.0
V
<9>
Min: 0.0 V
Max: 255.0 V <9>
T1-04 Motor Rated Current Sets the motor rated current as specified on the motor nameplate.
Default:
<4>
Min: 10% of drive
rated current
Max: 200% of
drive rated
current
<10>

Default: 50.0 Hz
Min: 0.0 Hz
Max: 200.0 Hz
T1-06 Number of Motor Poles Sets the number of motor poles as specified on the motor nameplate.
Default: 4
Min: 2
Max: 48
T1-07 Motor Base Speed Sets the rated speed of the motor as specified on the motor nameplate.
Default: 1450 r/
min

Min: 0 ppr
Max: 60000 ppr
T1-09
Motor No-Load Current
(Stationary Auto-Tuning 1
and 2)
Sets the no-load current for the motor.
After setting the motor capacity to T1-02 and the motor rated current to T1-04, this
parameter will automatically display the no-load current for a standard 4 pole
Yaskawa motor. Enter the no-load current as indicated on the motor test report.
Default: –
Min: 0 A
Max: Up to
T1-04
<10>
T1-10
Motor Rated Slip
(Stationary Auto-Tuning 2)
Sets the motor rated slip.
After setting the motor capacity to T1-02, this parameter will automatically display
the motor slip for a standard 4 pole Yaskawa motor. Enter the motor slip as indicated
on the motor test report.
Default: –
Min: 0.00 Hz
Max: 20.00 Hz
