11.6 E: Motor Parameters
■
E2-02: Motor Rated Slip
No.
Name
(Hex.)
E2-02 Motor Rated Slip
(030F)
RUN
The value set in E2-02 becomes the base slip compensation value. The drive sets this parameter during the Auto-
Tuning process (Rotational Auto-Tuning and Stationary Auto-Tuning). If Auto-Tuning cannot be performed,
calculate the motor rated slip using the information written on the motor nameplate and the formula below:
E2-02 = f - (n × p) / 120
• f: Motor rated frequency (Hz)
• n: Rated motor speed (min
• p: Number of motor poles
■
E2-03: Motor No-Load Current
No.
Name
(Hex.)
E2-03 Motor No-Load
Current
(0310)
Note:
The units for the default setting and setting range vary depending on the model of the drive.
• 2004 to 2042, 4002 to 4023: 0.01 A units
• 2056 to 2415, 4031 to 4726: 0.1 A units
The drive sets this parameter during the Auto-Tuning process (Rotational Auto-Tuning and Stationary Auto-
Tuning). The motor no-load current listed in the motor test report can also be entered to E2-03 manually. Contact
the motor manufacturer to receive a copy of the motor test report.
Note:
The default setting of the no-load current is for performance with a 4-pole motor recommended by Yaskawa.
■
E2-04: Motor Pole Count
No.
Name
(Hex.)
E2-04 Motor Pole Count
(0311)
The value of E2-04 is automatically set to the value input for [Number of Motor Poles] by the Auto-Tuning
process.
■
E2-05: Motor Line-to-Line Resistance
No.
Name
(Hex.)
E2-05 Motor Line-to-Line
Resistance
(0312)
Note:
This value represents the motor line-to-line resistance. Be careful not to set this parameter with the single phase resistance.
If Auto-Tuning completes successfully, this value is automatically calculated. If Auto-Tuning cannot be executed,
obtain a test report from the motor manufacturer. Use the information found on the motor nameplate with any of
the following formulas to calculate the motor line-to-line resistance.
• E-type insulation: Multiply 0.92 times the resistance value (Ω) listed on the test report at 75 °C.
• B-type insulation: Multiply 0.92 times the resistance value (Ω) listed on the test report at 75 °C.
• F-type insulation: Multiply 0.87 times the resistance value (Ω) listed on the test report at 115 °C.
