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).

E2-07: Motor Iron-Core Saturation Coefficient 1
Sets the motor iron saturation coefficient at 50% of the magnetic flux. If Rotational Auto-Tuning completes successfully, then
this value is automatically calculated and set to E2-07. This coefficient is used when operating with constant output.

E2-09: Motor Mechanical Loss
Sets the motor mechanical loss as a percentage of motor rated power (kW) capacity.
Adjust this setting in the following circumstances:
• When there is a large amount of torque loss due to motor bearing friction.
• When there is a large amount of torque loss in a fan or pump application.
The setting for the mechanical loss is added to the torque.
