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.
■
E2-09: Motor Mechanical Loss
No.
Name
(Hex.)
E2-09 Motor Mechanical Loss
(0316)
Expert
Adjust this parameter in these conditions. The drive adds the configured mechanical loss to the torque reference value
as a torque compensation value:
• There is a large quantity of torque loss from motor bearing friction.
• There is a large quantity of torque loss in fans and pumps.
■
E2-10: Motor Iron Loss
No.
Name
(Hex.)
E2-10 Motor Iron Loss
(0317)
■
E2-11: Motor Rated Power
No.
Name
(Hex.)
E2-11 Motor Rated Power
(0318)
The drive automatically sets this parameter to the value input for "Motor Rated Power" during Auto-Tuning.

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.
V/f CL-V/f OLV CLV AOLV
Sets the mechanical loss of the motor. It is set as a percentage of E2-11 [Motor Rated Power].
Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the motor iron loss.
V/f CL-V/f OLV CLV AOLV
Sets the motor rated output in the units from o1-58 [Motor Power Unit Selection].
