E2-04: Motor Pole Count
No.
(Hex.)
Name Description
Default
(Range)
E2-04
(0311)
Motor Pole Count
Sets the number of motor poles.
4
(2 - 120)
Note:
•
When A1-02 = 0 [Control Method = V/f Control] , the maximum value is 120.
•
When A1-02 = 2 [OLVector] , the maximum value is 48.
Auto-Tuning automatically sets this parameter to the value of [Number of Motor Poles].
■
E2-05: Motor L-L Resistance
No.
(Hex.)
Name Description
Default
(Range)
E2-05
(0312)
Motor L-L Resistance
Sets the line-to-line resistance for the motor stator windings.
Determined by o2-04, C6-
01
(0.000 - 65.000 Ω)
Note:
This value is the motor line-to-line resistance. Do not set this parameter with the single-phase resistance.
Auto-Tuning automatically sets this parameter. If you cannot do Auto-Tuning, use the test report from the motor
manufacturer to configure the settings. You can calculate the motor line-to-line resistance with one of these
formulas:
• E-type insulation: [the resistance value (Ω) shown on the test report at 75 °C] × 0.92
• B-type insulation: [the resistance value (Ω) shown on the test report at 75 °C] × 0.92
• F-type insulation: [the resistance value (Ω) shown on the test report at 115 °C] × 0.87
■
E2-06: Motor Leak Inductance
No.
(Hex.)
Name Description
Default
(Range)
E2-06
(0313)
Motor Leak Inductance
Sets the voltage drop from motor leakage inductance when the motor is operating at the rated
frequency and rated current. This value is a percentage of Motor Rated Voltage.
Determined by o2-04, C6-
01
(0.0 - 60.0%)
The drive automatically sets this parameter during Auto-Tuning.
Note:
The motor nameplate does not usually show the quantity of voltage drop. If you do not know the value of the motor leakage inductance,
contact the motor manufacturer to receive a copy of the motor test report.
■
E2-07: Mot Sat Coeff 1
No.
(Hex.)
Name Description
Default
(Range)
E2-07
(0314)
Mot Sat Coeff 1
Sets the motor iron-core saturation coefficient at 50% of the magnetic flux.
0.50
(0.00 - 0.50)
The drive uses this coefficient when it operates with constant output. The drive uses this coefficient when it
operates the motor in the constant output range.
■
E2-08: Mot Sat Coeff 2
No.
(Hex.)
Name Description
Default
(Range)
E2-08
(0315)
Mot Sat Coeff 2
Sets the motor iron-core saturation coefficient at 75% of the magnetic flux.
0.75
(E2-07 - 0.75)
The drive uses this coefficient when it operates with constant output. The drive uses this coefficient when it
operates the motor in the constant output range.
