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.
No. Parameter Name Setting Range Default
E2-09 Motor Mechanical Loss 0.0 to 10.0% 0.0%
Adjust this setting 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.
n
E2-10: Motor Iron Loss for Torque Compensation
This parameter sets the motor iron loss in watts.
No. Parameter Name Setting Range Default
E2-10 Motor Iron Loss for Torque Compensation 0 to 65535 W

n
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.

E3: V/f Characteristics for Motor 2
These parameters set the V/f pattern used for motor 2. Refer to Setting 16: Motor 2 Selection on page 181 for details on
switching motors.
n
E3-01: Motor 2 Control Mode Selection
Selects the control mode for motor 2. Motor 2 can not be used with OLV for PM.
No. Parameter Name Setting Range Default
E3-01 Motor 2 Control Mode Selection 0 or 2 0
Setting 0: V/f Control
Setting 2: Open Loop Vector Control
n
E3-04 to E3-13
Parameters E3-04 through E3-13 set up the V/f pattern used for motor 2 like shown in Figure 5.43.
