Parameter Name Setting Range Default Min. Unit
F1-01 Rated motor power 0–750 W Model dependent 1 W
F1-02 Rated motor voltage 0–250 V 100 V 1 V
F1-03 Rated motor current 0.001–9.900 A Model dependent 0.001 A
F1-04 Rated motor frequency 1.00–99.00 Hz 24.00 Hz 0.01 Hz

Set the parameters according to the motor nameplate. Ensure that these motor parameters
are set correctly. Incorrect setting affects the motor auto-tuning and the vector control effect.

Select a proper motor model according to the adaptable motor power. If there is a great
difference between the actual motor power and the adaptable motor power, the system control
performance will degrade.
F1-06 to F1-14 are updated automatically after motor auto-tuning is completed successfully.
For an asynchronous motor, the NICE900 obtains the corresponding parameters through
complete auto-tuning or static auto-tuning. If the onsite conditions does not allow motor auto-
tuning, manually input the value of these parameters by referring to data of the motor with the
same nameplate parameters.
Each time F1-01(Rated motor power) is changed, the controller automatically resumes
parameters F1-06 to F1-10 to the default values.
For a PMSM, the NICE900 can obtain F1-06 and F1-11 to F1-14 through complete auto-
tuning. After F1-01 is changed, the related parameters will not update.
F1-15 is used to display the magnetic pole position of the motor in real time.
