<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.

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.
Sets the motor rated voltage as specified on the motor nameplate.
Sets the motor rated current as specified on the motor nameplate.
Sets the rated frequency of the motor as specified on the motor nameplate.
Sets the number of motor poles as specified on the motor nameplate.
Sets the rated speed of the motor as specified on the motor nameplate.
Set the number of pulses per revolution for the PG being used (pulse generator or
encoder).
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.
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.
