5.5 E: Motor Parameters

■ E2-11: Motor Rated Power
This parameter sets the motor rated power in kW. If Auto-Tuning completes successfully, the value entered to T1-02 will
automatically be saved to E2-11.
■
Setting Motor Parameters Manually
Follow the instructions below when setting motor-related parameters manually instead of using the Auto-Tuning feature.
Refer to the motor test report included with the motor to make sure the correct data is entered into the drive.
Setting the Motor Rated Current
Enter the motor rated current listed on the nameplate of the motor to E2-01.
Setting the Motor Rated Slip
Use the base speed listed on the motor nameplate to calculate the rated slip. 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
Setting the No-Load Current
Enter the no-load current at rated frequency and rated voltage to E2-03. The no-load current 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.
Setting the Line-to-Line Resistance
E2-05 is normally set during Auto-Tuning. If Auto-Tuning cannot be performed, contact the manufacturer of the motor to
find out what the correct resistance is between motor lines. The motor test report can also be used to calculate this value:
• E-type insulation: Multiply 0.92 times the resistance value (
Ω) listed on the test report at 75°C.
• B-type insulation: Multiply 0.92 times the resistance value (
Ω) listed on the test report at 75°C.
• F-type insulation: Multiply 0.87 times the resistance value (
Ω) listed on the test report at 115°C.
Setting the Motor Leakage Inductance
The motor leakage inductance set to E2-06 determines the amount of voltage drop relative to the motor rated voltage.
This value should be entered particularly for motors with a low degree of inductance, such as high-speed motors. As this
information is not listed on the motor nameplate, contact the motor manufacturer to find out the correct value for the
motor leakage inductance.
Setting the Motor Iron Loss for Torque Compensation
This value only needs to be set when using V/f Control. Enter this value in watts to E2-10. The drive uses this setting to
improve the precision of torque compensation.
◆ E5: PM Motor Settings
These parameters set the motor data of a PM motor.
When Yaskawa motors are used, entering the motor code written on the motor nameplate will set up the E5-
parameters.
For all other PM motors, Auto-Tuning can be performed. If motor data is known, it can also be entered manually.
Note: 1. E5- parameters are visible only when a PM motor control mode is selected (A1-02 = 5).
2. E5- parameters are not reset when the drive is initialized using parameter A1-03.
No.
<1> The display resolution depends on the motor rated power. Drive models 2A0004 to 2A0415 and 4A0002 to 4A0515 will display this value in
units of 0.01 kW (two decimal places). Models 4A0675 to 4A1200 will display this value in units of 0.1 kW (one decimal place). Refer to
Model Number and Nameplate Check on page 29 for details.
