<1> The availability of certain Auto-Tuning methods depends on the control mode selected for the drive.
<2> Default setting is determined by parameter A1-02, Control Method Setting.
<3> Default setting is dependent on parameter o2-04, Drive Model Selection.
<4> Values shown are specific to 200 V class drives. Double the value for 400 V class drives. Multiply the value by 2.875 for 600 V class drives.
<5> Default setting value differs depending on the motor code value and motor parameter settings.

Sets the motor rated power as specified on the motor nameplate.
Note: Use the following formula to convert horsepower into kilowatts: kW
= HP x 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.
Sets 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.
Sets the iron loss for determining the Energy Saving coefficient.
The value is set to E2-10 (motor iron loss) set when the power is cycled. If
T1-02 is changed, a default value appropriate for the motor capacity that was
entered will appear.
