Motor 1 (Auto-tuning)
The inverter automatically detects the motor parameters and saves them in its internal memory. If using a Fuji
standard motor (incl. old model IE1 induction motors and synchronous motors) with a standard connection method,
there is generally no need to perform tuning.
There are two types of auto-tuning as listed below. Select the appropriate one considering the limitations in your
equipment and control mode. In the following table, IM indicates induction motor, and PM indicates synchronous
motor.
