Individual Functions
6-119
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.
