Motor Leak Inductance Setting
Set the amount of voltage drop due to motor leak inductance in E2-06 using the percentage over the motor
rated voltage. Make this setting when the high-speed motor inductance is small. If the inductance is not writ-
ten on the motor nameplate, consult the motor manufacturer.
Motor Iron Saturation Coefficients 1, 2 and 3 Settings
E2-07, E2-08 and E2-12 are set automatically using rotational autotuning.
Motor Iron Loss for Torque Compensation Setting
E2-10 is displayed only when in V/f control method. To increase the torque compensation accuracy when in
V/f control method, set the motor iron loss in Watts.
Motor Mechanical Loss
When using flux vector control, adjust mechanical loss in the following cases. (There is normally no reason to
make this adjustment.) The mechanical loss setting is used to compensate the torque.
• There is excessive torque loss from the motor bearings.
• There is excessive torque loss from a fan, pump, etc.
