E2-04: Motor Pole Count
No.
Name
(Hex.)
E2-04 Motor Pole Count
(0311)
Note:
• When A1-02 = 0, 1, 3 [Control Method Selection = V/f, CL-V/f, CLV], the maximum value is 120.
• When A1-02 = 2, 4 [OLV, AOLV], the maximum value is 48.
Auto-Tuning automatically sets this parameter to the value of [Number of Motor Poles].
■
E2-05: Motor Line-to-Line Resistance
No.
Name
(Hex.)
E2-05 Motor Line-to-Line
Resistance
(0312)
Note:
This value is the motor line-to-line resistance. Do not set this parameter with the resistance per phase.
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] × 0.822
• B-type insulation: [the resistance value (Ω) shown on the test report at 75 °C] × 0.822
• F-type insulation: [the resistance value (Ω) shown on the test report at 115 °C] × 0.728
■
E2-06: Motor Leakage Inductance
No.
Name
(Hex.)
E2-06 Motor Leakage Inductance
(0313)
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: Motor Saturation Coefficient 1
No.
Name
(Hex.)
E2-07 Motor Saturation Coefficient
1
(0314)
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: Motor Saturation Coefficient 2
No.
Name
(Hex.)
E2-08 Motor Saturation Coefficient
2
(0315)
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.

V/f CL-V/f OLV CLV AOLV
Sets the number of motor poles.
V/f CL-V/f OLV CLV AOLV
Sets the line-to-line resistance for the motor stator windings.
V/f CL-V/f OLV CLV AOLV
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.
V/f CL-V/f OLV CLV AOLV
Sets the motor iron-core saturation coefficient at 50% of the magnetic flux.
V/f CL-V/f OLV CLV AOLV
Sets the motor iron-core saturation coefficient at 75% of the magnetic flux.
