E2-09 Motor Mechanical Loss
Displayed only when using Open Loop Vector Control. It is not
necessary to set this parameter, but it may require adjustment
under the following circumstances:
Large amount of torque loss relative to motor bearings
Fan and pump type applications that have a large amount of
torque loss
The amount of mechanical loss will be reflected in the amount of
torque compensation.
359
E2-10
Motor Iron Loss for
Torque Compensation
Displayed only when using V/f Control. Increase the motor iron
loss in watts in order to increase the accuracy of torque
compensation.
359
E2-11 Motor Rated Output
Sets the motor rated power in kilowatts (kW). This value is
automatically set during Auto-Tuning in units of 0.01
(1HP = 0.746 kW).
359
E2-12
<1>
Motor Iron-Core
Saturation Coefficient 3
Set to the motor iron saturation coefficient at 130% of magnetic
flux. This value is automatically set during rotational
Auto-Tuning.
360
<1> Parameters E2-07 through E2-08 and E2-12 may be difficult to set manually. If Auto-Tuning is not
possible, simply leave these settings at the default values.
