Motor Line-to-Line Resistance Setting (E2-05, E4-05)
E2-05 is set automatically during motor line-to-line resistance autotuning. When it can not be performed for
any reason, consult the motor manufacturer for the line-to-line resistance value. The set value should be calcu-
late the motor test report line-to-line resistance value and the following formula:
• E-type insulation: [Line-to line resistance (Ω) at 75°C of test report] × 0.92 (Ω)
• B-type insulation: [Line-to line resistance (Ω) at 75°C of test report] × 0.92 (Ω)
• F-type insulation: [Line-to line resistance (Ω) at 115°C of test report] × 0.87 (Ω)
Motor Leak Inductance Setting (E2-06, E4-06)
Set the amount of voltage drop due to motor leakage inductance in E2-06 as a percentage of the motor rated
voltage. If the inductance is not written on the motor nameplate, consult the motor manufacturer.
Motor Iron Saturation Coefficients 1 and 2 Settings (E2-07/08)
E2-07 and E2-08 are set automatically during rotating autotuning.
Motor Iron Loss for Torque Compensation Setting (E2-10)
E2-10 is displayed only in V/f control method and can be set to increase the torque compensation accuracy.
Motor Setting 1/2 Switch Over
Refer to page 6-55, Motor 2 Selection.
 Setting Motor Parameters for PM Motors
The autotuning with rotating motor can be used to let the inverter measure the voltage constant, the line-to-line
resistance and the q- and d-axis inductances and the encoder offset (refer to page 4-7, Autotuning Procedure
with PM Motors. It can be performed only if the motor can rotate freely (removed ropes and open brake). If
the autotuning can not be performed for any reason, the following motor parameters must be set manually.
