■ E4-04: Motor 2 Motor Poles
Set the pole number of motor 2 to E4-04. If Auto-Tuning completes successfully, the entered value to T1-06 will be
automatically saved to E4-04.
■
E4-05: Motor 2 Line-to-Line Resistance
Sets the line-to-line resistance for the motor 2 stator winding. If Auto-Tuning completes successfully, this value is
automatically calculated. Remember this value must be entered as line-to-line and not for each motor phase. Refer to E2-
05: Motor Line-to-Line Resistance on page 199 to manually enter this parameter setting.
■
E4-06: Motor 2 Leakage Inductance
Sets the voltage drop due to motor leakage inductance as a percentage of rated voltage of motor 2. This value is
automatically set during Auto-Tuning (Rotational Auto-Tuning and Stationary Auto-Tuning 1, 2).
■
E4-07: Motor 2 Motor Iron-Core Saturation Coefficient 1
Sets the motor 2 iron saturation coefficient at 50% of magnetic flux. This value is automatically set during Rotational
Auto-Tuning. Adjust this parameter when operating in the constant output range.
■
E4-08: Motor 2 Motor Iron-Core Saturation Coefficient 2
Sets the motor iron saturation coefficient at 75% of magnetic flux. This value is automatically set during Rotational
Auto-Tuning. Adjust this parameter when operating in the constant output range.
■
E4-09: Motor 2 Mechanical Loss
Sets the motor mechanical loss as a percentage of motor rated power (kW).
This parameter seldom needs to be changed, but may need to be adjusted 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.
■
E4-10: Motor 2 Iron Loss
Sets the motor 2 iron loss in watts.
