■ E4-06: M2 Leak Inductance
No.
(Hex.)
Name Description
Default
(Range)
E4-06
(0326)
M2 Leak 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, C6-
01
(0.0 - 60.0%)
The drive sets this parameter during Rotational Auto-Tuning and Stationary Auto-Tuning.
Note:
You cannot usually find the quantity of voltage drop on the motor nameplate. If you do not know the value of the motor 2 leakage
inductance, get the test report from the motor manufacturer.
■ E4-07: M2 Satur Coeff 1
No.
(Hex.)
Name Description
Default
(Range)
E4-07
(0343)
M2 Satur Coeff 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: M2 Satur Coeff 2
No.
(Hex.)
Name Description
Default
(Range)
E4-08
(0344)
M2 Satur Coeff 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: M2 Mech Loss
No.
(Hex.)
Name Description

M2 Mech Loss
Sets the mechanical loss of motor 2. It is set as a percentage of E4-11 [M2 Rated Power (kW)].
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: M2 Iron Loss
No.
(Hex.)
Name Description
Default
(Range)
E4-10
(0340)
M2 Iron Loss
Sets the motor iron loss for motor 2.
Determined by o2-04, C6-
01
(0 - 65535 W)
■ E4-11: M2 Rated Power (kW)
No.
(Hex.)
Name Description
Default
(Range)
E4-11
(0327)
M2 Rated Power (kW)
Sets the motor rated power in the units from o1-58 [Mot Capacity Unit].
Determined by o2-04, C6-
01
(0.00 - 650.00 kW)
Auto-Tuning automatically sets this parameter to the value input for [Motor Rated Power].
◆ E5: PM MOTOR SETTINGS
E5 parameters are used to set PM motor data.
