11.6 E: Motor Parameters
This value is automatically set during Auto-Tuning (Rotational Auto-Tuning, Stationary Auto-Tuning).
Note:
The amount of voltage drop cannot normally 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: Motor2 Saturation Coefficient 1
No.
Name
(Hex.)
E4-07 Motor2 Sauturation
Coefficient 1
(0343)
Performing the Rotational Auto-Tuning configures this parameter with the automatically calculated value. This
coefficient is used when operating with constant output.
■
E4-08: Motor2 Saturation Coefficient 2
No.
Name
(Hex.)
E4-08 Motor 2 Saturation
Coefficient 2
(0344)
Performing the Rotational Auto-Tuning configures this parameter with the automatically calculated value. This
value is used to operate the motor at constant output.
■
E4-09: Motor 2 Mechanical Loss
No.
Name
(Hex.)
E4-09 Motor 2 Mechanical
Loss
(033F)
Adjust this parameter in the following circumstances. The configured mechanical loss is added to the torque
reference value as a torque compensation value.
• Torque loss due to motor bearing friction is significant.
• Torque loss of fans and pumps is significant.
■
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)
The value of E4-11 is automatically set to the value input for [Motor Rated Power] by the Auto-Tuning process.
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.
The maximum applicable motor output varies depending on C6-01 [Normal / Heavy Duty Selection].

V/f CL-V/f OLV CLV AOLV
Sets the motor 2 iron-core saturation coefficient at 50% of the magnetic
flux.
V/f CL-V/f OLV CLV AOLV
Sets the motor 2 iron-core saturation coefficient at 75% of the magnetic
flux.
V/f CL-V/f OLV CLV AOLV
Configures the mechanical loss of motor 2. The motor rated power (kW) is
100%. Normally there is no need to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the motor iron loss for motor 2 in watts.
V/f CL-V/f OLV CLV AOLV
Sets the motor 2 rated power in 0.01 kW. (1 HP = 0.746 kW)
