E2-03: 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.

Note:
The number of decimal places in the parameter value depends on the drive model 1. This value has two decimal places (0.01 A) if the drive
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.
Refer to Power Ratings on page 396

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.
• 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.
