5.5 E: Motor Parameters
152 YASKAWA ELECTRIC SIEP C710606 44B YASKAWA AC Drive T1000V Technical Manual
â—† E4: Motor 2 Parameters
E4 parameters contain the motor data for motor 2. These parameters are usually set automatically during the Auto-
Tuning process. They may need to be set manually if there is a problem performing Auto-Tuning.
â–
E4-01: Motor 2 Rated Current
Set E4-01 to the full load amps (FLA) stamped on the nameplate of motor 2. During Auto-Tuning the value must be
entered to parameter T1-04. If Auto-Tuning completes successfully, the value entered will automatically be saved to E4-
01.
Note: Setting units vary by the maximum allowable motor capacity, which is determined by C6-01 and o2-04. Drives up to 11 kW
display a two-digit value, while drives 11 kW and larger display a single-digit value.
â– E4-02: Motor 2 Rated Slip
This parameter sets the motor 2 rated slip frequency. The drive calculates this value automatically during Rotational
Auto-Tuning.
For information on calculating the motor rated slip, see the description for E2-02.
â–
E4-03: Motor 2 Rated No-Load Current
Set E4-03 to the motor no-load current at rated voltage and rated frequency. If Rotational Auto-Tuning completes
successfully, this value is automatically calculated. If Auto-Tuning can not be performed contact the motor manufacturer
for information about the no-load current.
Note: Setting units vary by the maximum allowable motor capacity, which is determined by C6-01 and o2-04. Drives up to 11 kW
display a two-digit value, while drives 11 kW and larger display a single-digit value.
â– 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.
â–
E4-05: Motor 2 Line-to-Line Resistance
Sets the line-to-line resistance of motor 2 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.
Refer to E2-05: Motor Line-to-Line Resistance on page 149 to manually enter this parameter setting.
