E4-04
(0324)
Motor 2 Motor Poles
Sets the number of poles for motor 2.
4
(2 - 120)
Auto-Tuning automatically sets
E4-04
to the value input for [Number of Motor Poles].
E4-05: Motor 2 Line-to-Line Resistance

Motor 2 Line-to-Line
Resistance
Sets the line-to-line resistance for motor 2 stator windings.
Determined by o2-04
(0.000 - 65.000 Ω)
Note:
This value represents the line-to-line resistance for motor 2. Be careful not to set this parameter with the single phase resistance.
If Auto-Tuning completes successfully, this value is automatically calculated. If Auto-Tuning cannot be executed,
obtain a test report from the motor manufacturer. Use the information found on the motor nameplate with any of
the following formulas to calculate the motor line-to-line resistance.
•
E-type insulation: Multiply 0.92 times the resistance value (Ω) listed on the test report at 75 °C.
•
B-type insulation: Multiply 0.92 times the resistance value (Ω) listed on the test report at 75 °C.
•
F-type insulation: Multiply 0.87 times the resistance value (Ω) listed on the test report at 115 °C.
E4-06: Motor 2 Leakage Inductance
No.
(Hex.)
Name
Description
Default
(Range)
E4-06
(0326)
Motor 2 Leakage
Inductance
Sets the voltage drop due to motor 2 leakage inductance as a percentage of
motor 2 rated voltage while the motor 2 is operating at the rated frequency
and rated current.
Determined by o2-04
(0.0 - 60.0%)
This value is automatically set during Auto-Tuning (Rotational Auto-Tuning, Stationary Auto-Tuning).
Note:
The amount of voltage drop cannot usually be found on the motor nameplate. If the value of the motor 2 leakage inductance is unknown,
obtain a test report from the motor manufacturer.
E4-07: Motor 2 Saturation Coefficient 1
No.
(Hex.)
Name
Description
Default
(Range)
E4-07
(0343)
Motor 2 Saturation
Coefficient 1
Sets the motor 2 iron-core saturation coefficient at 50% of the magnetic
flux.
0.50
(0.00 - 0.50)
The drive sets this parameter during Rotational Auto-Tuning. The drive uses this coefficient when it operates with
constant output.
E4-08: Motor 2 Saturation Coefficient 2
No.
(Hex.)

Description
Default
(Range)
E4-08
(0344)
Motor 2 Saturation
Coefficient 2
Sets the motor 2 iron-core saturation coefficient at 75% of the magnetic
flux.
0.75
(E4-07 - 0.75)
The drive sets this parameter during Rotational Auto-Tuning. The drive uses this value to operate the motor at
constant output.
