Setting the Motor Iron-Core Saturation Coefficient 1, 2
E2-07 and E2-08 are set when Auto-Tuning is performed.
Setting the Motor Mechanical Loss
Only required in Closed Loop Vector Control. The drive compensates for the degree of mechanical loss with torque
compensation. Although E2-09 rarely needs to be changed, adjustment may benefit when there is a large amount of
torque loss due to motor bearing friction.
Setting the Motor Iron Loss for Torque Compensation
Only required when using V/f Control. Enter this value in watts to E2-10. The drive uses this setting to improve the
precision of torque compensation.
◆ E3: V/f Pattern for Motor 2
These parameters set the V/f pattern used for motor 2. Refer to Setting 16: Motor 2 selection on page 195 for details on
switching motors.
Note: The function for switching between two motors cannot be used with a PM motor. E3-†† parameters are hidden when a PM
motor control mode is selected (A1-02 = 7).
■ E3-04 to E3-10
Parameters E3-04 through E3-10 set up the V/f pattern used for motor 2 as shown in Figure 5.14 .
Note: Certain E3-†† parameters might not be visible depending on the control mode. Refer to Parameter List on page 365 for details.
Figure 5.14
Figure 5.14 V/f Pattern for Motor 2
Note: 1. The following conditions must be true when setting up the V/f pattern: E3-09 ≤ E3-07 < E3-06 ≤ E3-04
2. To make the V/f pattern a straight line at a frequency lower than E3-07, set E3-09 equal to E3-07. In this case the E3-08 setting is
disregarded.
3. Parameters E3-04 through E3-10 are reset to their default values when the drive is initialized.
No.
<1> Values shown here are for 200 V class drives. Double the value when using a 400 V class drive.
<2> Default setting value is dependent on the drive model (o2-04).
