5.5 E: Motor Parameters
♦ 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 173
for details on
switching motors.
Note: The function for switching between tw o motors cannot be used w ith a PM motor. E 3 -D D param eters are hidden when a PM
m otor 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 E 3 -D D param eters m ight not be visible depending on the control mode.
Refer to Param eter Table on page 324
for
details.

Note: 1. The following conditions must be true w hen 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 low er than E3-07, set E3-09 equal to E3-07. In this case the E3-08 setting is
disregarded.
3. Param eters E3-04 through E3-10 are reset to their default values when the drive is initialized.
♦ E4: Motor 2 Parameters
E4 parameters contain the motor data for motor 2. These parameters are usually set automatically during the Auto
Tuning process for vector control modes (Rotational Auto-Tuning, Stationary Auto-Tuning 1 and 2). If Auto-Tuning
cannot be performed, refer to
Auto-Tuning Fault Detection on page 260
for additional details.
Note: The function for switching between tw o motors cannot be used w ith a PM motor. E 4 -D D param eters are hidden when a PM
m otor control mode is selected (A1-02 = 7).
■ E4-01: Motor 2 Rated Current
Protects the motor and calculates torque limits. Set E4-01 to the full load amps (FLA) stamped on the nameplate o f motor
2
.
If Auto-Tuning completes successfully, the value entered to T1-04 will automatically be saved to E4-01.

E4-01
Motor 2 Rated Current
10 to 200% o f the drive rated current.
Determined by o2-04
Note: 1. The display resolution depends on the rated output power o f the drive. M odels C IM R -LD 2A 0018 to 0033 and CIMR-LIH4A0009 to
0018 display values in 0.01 A units, while models C IM R -LD 2A 0047 to 2A0415 and CIMR-LIH4A0024 to 4A 0216 display values in
0.1 A units.
2. A n oPE02 error will occur if the m otor rated current in E4-01 is set low er than the m otor no-load current in E4-03. Set E4-03
correctly to prevent this error.
