: Set the motor's rated capacity according to the motor's name plate or test report.
f415
: Set the rated current of the motor. For the rated current, see the motor's nameplate or test report.
f417
: Set the rated rotational speed of the motor. For the rated current, see the motor's nameplate or test
report.

Adjustment method for the moment of inertia of the load
f459
: Adjusts the excess response speed. A larger value gives a smaller overshoot at the
acceleration/deceleration completion point. In the default settings, the moment of inertia of the load
(including the motor shaft) value is optimally set considering a motor shaft of 1x. When the
moment of inertia of the load is not 1x, set a value that matches that actual moment of inertia of
the load.
thr
: If the rated capacity of the motor is one size smaller than that of the inverter, lower the thermal
protective level according to the rated current of the motor.
* Sensorless vector control may not operate properly if the motor capacity differs from the
applicable rated capacity of the inverter by more than two grades.
Caution:
If a combination of the inverter rating and the motor capacity is different for more than 2 items, vector
control may not operate correctly.
[Selection 3: Setting PM motor control and optimization of starting torque]
Even if auto-tuning is done, motor cannot start due to heavy load, set the
f915
to
4
to activate the
optimization of starting torque.
