E2-04: Number of Motor Poles
Set the number of motor poles to E2-04. If Auto-Tuning completes successfully, the value entered to T1-06 will automatically
be saved to E2-04.

E2-05:Motor Line-to-Line Resistance
Sets the line-to-line resistance of the motor stator winding. If Auto-Tuning completes successfully, this value is automatically
calculated. Enter this value as line-to-line and not for each motor phase.
If Auto-Tuning is not possible, contact the motor manufacturer to find out the line-to-line resistance or measure it manually.
When using the manufacturer motor test report, calculate E2-05 by one of the formulas below:
• E-type insulation: Multiply 0.92 times the resistance value (Ω) listed on the test report at 75 °C (167 °F).
• B-type insulation: Multiply 0.92 times the resistance value (Ω) listed on the test report at 75 °C (167 °F).
• F-type insulation: Multiply 0.87 times the resistance value (Ω) listed on the test report at 115 °C (239 °F).

Setting Motor Parameters Manually
Follow the instructions below when setting motor-related parameters manually instead of Auto-Tuning. Refer to the motor
test report included with the motor to ensure the correct data is entered into the drive.
Set the Motor Rated Current
Enter the motor rated current listed on the nameplate of the motor to E2-01.
Set the Motor Rated Slip
Calculate the motor rated slip using the base speed listed on the motor nameplate. Refer to the formula below, then enter that
value to E2-02.
Motor rated slip = rated frequency [Hz] – base speed [r/min] × (no. of motor poles) / 120
Set the No-Load Current
Enter the no-load current at rated frequency and rated voltage to E2-03. This information is not usually listed on the nameplate.
Contact the motor manufacturer if the data cannot be found.
The default setting of the no-load current is for performance with a 4-pole Yaskawa motor.
