5.5 E: Motor Parameters
If Auto-Tuning is not possible, then 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 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.

E2-06: Motor Leakage Inductance
Sets the voltage drop due to motor leakage inductance as a percentage of motor rated voltage.
No.
E2-06
n E2-07: Motor Iron-Core Saturation Coefficient 1
This parameter sets the motor iron saturation coefficient at 50% of the magnetic flux. If Rotational Auto-Tuning completes
successfully, then this value is automatically calculated.
No.
E2-07
n E2-08: Motor Iron-Core Saturation Coefficient 2
This parameter sets the motor iron saturation coefficient at 75% of the magnetic flux. If Rotational Auto-Tuning completes
successfully, then this value is automatically calculated.
No.
E2-08
n E2-09: Motor Mechanical Loss
This parameter sets to the motor mechanical loss as a percentage of motor rated power (kW) capacity.
No.
E2-09
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.
n E2-10: Motor Iron Loss for Torque Compensation
This parameter sets the motor iron loss in watts.
No.
E2-10
n E2-11: Motor Rated Power
This parameter sets the motor rated power in kW. During Auto-Tuning the value must entered to parameter T1-02. If Auto-
Tuning completes successfully, the value entered will automatically be saved to E2-11.
No.
E2-11
n E2-12: Motor Iron-Core Saturation Coefficient 3
This parameter sets the motor iron saturation coefficient at 130% of the magnetic flux.
No.
E2-12
