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.
No.
E2-04
n
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.
No.
E2-05
n
E2-06: Motor Leakage Inductance
Sets the voltage drop due to motor leakage inductance as a percentage of motor rated voltage. This value is automatically
set during Auto-Tuning (Rotational Auto-Tuning, Stationary Auto-Tuning).
No.
E2-06
n
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.
No.
E2-07
n
E2-08: Motor Iron-Core Saturation Coefficient 2
Sets the motor iron saturation coefficient at 75% of the magnetic flux. If Rotational Auto-Tuning completes successfully,
then this value is automatically and set to E2-08. This coefficient is used when operating with constant output.
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.
Adjust this setting when there is a large amount of torque loss due to motor bearing friction.
The setting for the mechanical loss is added to the torque.
No.
E2-09
n
E2-10: Motor Iron Loss for Torque Compensation
Sets the motor iron loss in watts.
No.
