n
E4-04: Motor 2 Motor Poles
Sets the number of poles for motor 2. If Auto-Tuning completes successfully, the value entered to T1-06 will be automatically
saved to E4-04.
No. Parameter Name Setting Range Default
E4-04 Motor 2 Motor Poles 2 to 48 4
n
E4-05: Motor 2 Line-to-Line Resistance
Sets the line-to-line resistance for the motor 2 stator winding. If Auto-Tuning completes successfully, this value is automatically
calculated. Enter this value as line-to-line and not for each motor phase. Refer to E2-05: Motor Line-to-Line Resistance on
page 188 to manually enter this parameter setting.
No. Parameter Name Setting Range Default
E4-05 Motor 2 Line-to-Line Resistance 0.000 to 65.000 Ω
Determined by
C6-01 and o2-04
n
E4-06: Motor 2 Leakage Inductance
Sets the voltage drop due to motor leakage inductance as a percentage of rated voltage of motor 2. This value is automatically
set during Auto-Tuning (Rotational Auto-Tuning and Stationary Auto-Tuning 1, 2).
No. Parameter Name Setting Range Default
E4-06 Motor 2 Leakage Inductance 0.0 to 40.0%
Determined by
C6-01 and o2-04
n
E4-07: Motor 2 Motor Iron-Core Saturation Coefficient 1
Sets the motor 2 iron saturation coefficient at 50% of magnetic flux. This value is automatically set during Rotational Auto-
Tuning. Adjust this parameter when operating in the constant output range.
No. Parameter Name Setting Range Default
E4-07 Motor 2 Motor Iron-Core Saturation Coefficient 1 0.00 to 0.50 0.50
n
E4-08: Motor 2 Motor Iron-Core Saturation Coefficient 2
Sets the motor iron saturation coefficient at 75% of magnetic flux. This value is automatically set during Rotational Auto-
Tuning. Adjust this parameter when operating in the constant output range.
No. Parameter Name Setting Range Default
E4-08 Motor 2 Motor Iron-Core Saturation Coefficient 2 [E4-07] to 0.75 0.75
n
E4-09: Motor 2 Mechanical Loss
Sets the motor mechanical loss as a percentage of motor rated power (kW).
Although E4-09 rarely needs to be changed, adjustment may be necessary in the following circumstances:
• When there is a large amount of torque loss due to motor bearing friction.
• When there is a large amount of torque loss in a fan or pump application.
The setting for the mechanical loss is added to the torque.
No. Parameter Name Setting Range Default
E4-09 Motor 2 Mechanical Loss 0.0 to 10.0% 0.0%
n
E4-10: Motor 2 Iron Loss
Sets the motor 2 iron loss in watts.
No. Parameter Name Setting Range Default
E4-10 Motor 2 Iron Loss 0 to 65535 W
Determined by
C6-01 and o2-04
