E2-06: Motor Leakage Inductance
No.
(Hex.)
Name Description
Default
(Range)
E2-06
(0313)
Motor Leakage Inductance
Sets the voltage drop due to motor leakage inductance as a percentage of motor rated voltage
while the motor 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 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.
(Hex.)
Name Description
Default
(Range)
E2-07
(0314)
Motor Saturation
Coefficient 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: Motor Saturation Coefficient 2
No.
(Hex.)
Name Description
Default
(Range)
E2-08
(0315)
Motor Saturation
Coefficient 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.
■
E2-09: Motor Mechanical Loss
No.
(Hex.)
Name Description
Default
(Range)
E2-09
(0316)
Expert
Motor Mechanical Loss
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.
0.0%
(0.0 - 10.0%)
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.
(Hex.)
Name Description
Default
(Range)
E2-10
(0317)
Motor Iron Loss
Sets the motor iron loss.
Determined by o2-04
(0 - 65535 W)
■
E2-11: Motor Rated Power (kW)
No.
(Hex.)
Name Description
Default
(Range)
E2-11
(0318)
Motor Rated Power
Sets the motor rated power in 0.01 kW increments. (1 HP = 0.746 kW)
Determined by o2-04
(0.00 - 650.00 kW)
The drive automatically sets E2-11 to the value input for [Motor Rated Power] during Auto-Tuning.
Note:
The motor rated power unit changes when the maximum applicable motor output changes.
• The maximum applicable motor output ≤ 300 kW: 0.01 kW units
• The maximum applicable motor output > 300 kW: 0.1 kW units
