■
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.
■
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.
■
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.
■
E2-10: Motor Iron Loss for Torque Compensation
This parameter sets the motor iron loss in watts.
■
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.
■
E2-12: Motor Iron-Core Saturation Coefficient 3
This parameter sets the motor iron saturation coefficient at 130% of the magnetic flux.
