■ E4-06: Motor 2 Leakage Inductance
No.
(Hex.)
Name Description
Default
(Range)
E4-06
(0326)
Motor 2 Leakage
Inductance
Sets the voltage drop from motor 2 leakage inductance as a percentage of Motor Rated Voltage
when motor 2 operates 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 value when it operates the motor
in the constant output range.
■ E4-08: Motor 2 Saturation Coefficient 2
No.
(Hex.)
Name 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 when it operates the motor
in the constant output range.
■ E4-09: Motor 2 Mechanical Loss
No.
(Hex.)
Name Description
Default
(Range)
E4-09
(033F)
Expert
Motor 2 Mechanical Loss
Sets the mechanical loss of motor 2. It is set as a percentage of E4-11 [Motor 2 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.
■ E4-10: Motor 2 Iron Loss
No.
(Hex.)
Name Description
Default
(Range)
E4-10
(0340)
Motor 2 Iron Loss
Sets the motor iron loss for motor 2.
Determined by o2-04
(0 - 65535 W)
■ E4-11: Motor 2 Rated Power
No.
(Hex.)
Name Description
Default
(Range)
E4-11
(0327)
Motor 2 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 E4-11 to the value input for [Motor Rated Power] during Auto-Tuning.
Note:
The value appears in units of 300 kW when the maximum applicable motor output is less than 0.01 kW and appears in units of 300 kW
when over 0.1 kW.
