E4-06: Motor 2 Leakage Inductance
No.
Name
(Hex.)
E4-06 Motor 2 Leakage
Inductance
(0326)
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: Motor 2 Saturation Coefficient 1
No.
Name
(Hex.)
E4-07 Motor 2 Saturation
Coefficient 1
(0343)
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.
Name
(Hex.)
E4-08 Motor 2 Saturation
Coefficient 2
(0344)
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.
Name
(Hex.)
E4-09 Motor 2 Mechanical Loss
(033F)
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.
■
E4-10: Motor 2 Iron Loss
No.
Name
(Hex.)
E4-10 Motor 2 Iron Loss
(0340)
■
E4-11: Motor 2 Rated Power
No.
Name
(Hex.)
E4-11 Motor 2 Rated Power
(0327)
Auto-Tuning automatically sets this parameter to the value input for [Motor Rated Power].

V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
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.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the motor 2 iron-core saturation coefficient at 50% of the magnetic flux.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the motor 2 iron-core saturation coefficient at 75% of the magnetic flux.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
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.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the motor iron loss for motor 2.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the motor rated power in the units from o1-58 [Motor Power Unit Selection].
