E2-08 Motor Iron-core Saturation Coefficient 2
Setting Range: 0.50 to 0.75
Factory Default: 0.75
This parameter sets the motor iron saturation coefficient at 75% of the magnetic flux. If the rotational Auto-tuning operation
completes successfully (T1-02 = 0), this value is automatically calculated.
E2-09 Motor Mechanical Loss
Setting Range: 0.0 to 10.0 %
Factory Default: 0.0 %
This parameter sets to the motor mechanical loss as a percentage of motor rated power (kW) capacity. Adjust this setting in the
following circumstances:
· When torque loss is large due to motor bearing friction.
· When the torque loss in the load is large.
E2-10 Motor Iron Loss for Torque Compensation
Setting Range: 0 to 65535 W
Factory Default: Model Dependent
This parameter sets the motor iron loss in watts (W)
E2-11 Motor Rated Output
Setting Range: 0.00 to 650.00 kW
Factory Default: Model Dependent
This parameter sets the motor rated power in kilowatts (kW). If the rotational Auto-tuning operation completes successfully
(T1-02 = 0), this value is automatically calculated.
1 horsepower = 0.746 kilowatts
E2-12 Motor Iron-core Saturation Coefficient 3
Setting Range: 0.0 to 1.60
Factory Default: 1.30
This parameter sets the motor iron saturation coefficient at 130% of the magnetic flux. If the rotational Auto-tuning operation
completes successfully (T1-02 = 0), this value is automatically calculated.
