1.5 E: Motor Parameters
122 YASKAWA ELECTRIC SIEP C710606 10A YASKAWA AC Drive - V1000 PRELIM. Programming Manual
■ E4-04: Motor 2 Motor Poles
Set the pole number of motor 2 to E4-04. During Auto-Tuning the value must entered to
parameter T1-06. If Auto-Tuning completes successfully, the entered value will
automatically be saved to E4-04.
■ E4-05: Motor 2 Line-to-Line Resistance
Sets the line-to-line resistance of motor 2’s stator winding. If the Auto-tuning completes
successfully, this value is automatically calculated. Remember this value must be entered as
line-line and not line-neutral.
Note: The setting range is 0.00 to 130.00 when using a drive capacity of 0.2 kW or less.
To manually enter this parameter setting, refer to the description for E2-05.
■ E4-06: Motor 2 Leakage Inductance
Sets the voltage drop due to motor leakage inductance of motor 2. The value is set as a
percentage of the rated voltage.
■ 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.
■ 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.
