5.5 E: Motor Parameters

■
E3-04 to E3-13
Parameters E3-04 through E3-13 set up the V/f pattern used for motor 2 as shown in Figure 5.54 .
Note: Certain E3-  parameters might not be visible depending on the control mode. Refer to Parameter Table on page 468 .
Figure 5.54
Figure 5.54 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
≤
E3-11
≤
E3-04
2. To make the V/f pattern a straight line at a frequency lower than E3-06, set E3-09 = E3-07. With this setting, E3-08 is disregarded.
3. Parameters E3-04 through E3-13 are reset to their default values when the drive is initialized.
4. E3-11, E3-12, and E3-13 rarely need to be changed, and should only be used to fine-tune the V/f pattern in the constant output range.
◆
E4: Motor 2 Parameters
E4 parameters contain the motor data for motor 2. These parameters are usually set automatically during the
Auto-Tuning process (Rotational Auto-Tuning, Stationary Auto-Tuning 2 and 3). If Auto-Tuning cannot be performed,
refer to
Auto-Tuning Fault Detection on page 376 for detail.
Note: As the function for switching between two motors cannot be used with a PM motor, the E5-  parameters will be hidden when
a PM motor control mode is selected (A1-02 = 5, 6, or 7).
■ E4-01: Motor 2 Rated Current
Set E4-01 to the full load amps (FLA) stamped on the nameplate of motor 2. This value is used for motor protection and
to calculate torque limits. If Auto-Tuning completes successfully, the value entered to T1-04 will automatically be saved
to E4-01.
Note: 1. Display is in the following units.
 CIMR-U  2  0028, 2  0042, and 4  0011 to 4  0027: 0.01 A units
 CIMR-U  2  0054 to 2  0248, and 4  0034 to 4  0930: 0.1 A units
2. If the motor rated current in E4-01 is set lower than the motor no-load current in E4-03, then a parameter setting error will occur
(oPE02). E4-03 must be set correctly to prevent this error.
No.
<1> Values shown here are for 200 V class drives. Double the value when using a 400 V class drive.
<2> Default setting is determined by the control mode selected for motor 2 (E3-01).
<3> The drive sets this value when Auto-Tuning is performed (Rotational Auto-Tuning and Stationary Auto-Tuning 2).
<4> Parameter ignored when E3-11 and E3-12 are set to 0.0.
<5> The default value shown here is for the following localized drives: Japan (Model code: CIMR-UA  ), India (Model code: CIMR-UD  ), Asia
(Model code: CIMR-UT  ).
For default value of China localized drive (Model code: CIMR-UB  ), refer to Default Values of the China Localized Drive: CIMR-UB
