Setting procedure Adjust the following parameters:
f401 : Set the compensation gain for the slipping of the motor. A higher slip frequency reduces motor

f402 : Adjust the primary resistive component of the motor. Decreases in torque due to a possible voltage
f405 : 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.
f416 : Set the ratio of the no-load current of the motor to the rated current. Enter the value in % that is
f417 : Set the rated rotational speed of the motor. For the rated current, see the motor's nameplate or test

* 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.
If a combination of the inverter rating and the motor capacity is different for more than 2 classes,
vector control may not operate correctly.
