n
E4-06: Motor 2 Leakage Inductance
Sets the voltage drop due to motor leakage inductance as a percentage of rated voltage of motor 2.
n
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.
n
E4-08: Motor 2 Motor Iron-Core Saturation Coefficient 2
Sets the motor 2 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.
n
E4-09: Motor 2 Mechanical Loss
Sets the motor mechanical loss as a percentage of motor rated power (kW).
Although E4-09 rarely needs to be changed, adjustment may be necessary 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.
n
E4-10: Motor 2 Iron Loss
Sets the motor 2 iron loss in watts.
n
E4-11: Motor 2 Rated Power
Sets the motor 2 rated power. If Auto-Tuning completes successfully, the value entered to T1-02 will automatically be
saved to E4-11.
