E2 Motor No Load Current
Set the no-load current for the motor in amperes when operating at the rated frequency and the no-load voltage. The drive sets
E2-03 during the Auto-Tuning process (Rotational Auto-Tuning and Stationary Auto-Tuning 1, 2). The motor no-load current
listed in the motor test report can also be entered to E2-03 manually. Contact the motor manufacturer to receive a copy of the
motor test report.
No
E2-03
The number of decimal places in the parameter value depends on the drive model. This value has two decimal places (0.01 A) if the drive
Note:
is set for a maximum applicable motor capacity up to and including 11 kW, and one decimal place (0.1 A) if the maximum applicable motor
capacity is higher than 11 kW.
E2 Number o 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.
No
E2-04
E2 Motor Line to Line esistance
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).
No
E2-05
E2 1 Motor Iron Loss or or ue Compensation
Sets the motor iron loss in watts.
No
E2-10
E2 11 Motor ated Po er
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.
No
E2-11
Settin 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.
