Set the parameters based on the parameters on the nameplate of
the motor.
To guarantee the control performance, choose the standard
adaptive motor of the inverter. If a great difference exists
between the actual motor power and the adaptive motor power,
the control performance of the inverter may degrade.

frequency (F0-02)
To compensate the low frequency torque characteristics of V/F control,
you can boost the output voltage of the inverter at low frequency.
"Torque boost" (F0-10) is set to a certain percentage of the input rated
voltage of the inverter. The setting is as follows:
When this parameter is set to 0.0%, automatic torque boost is applied
for the inverter.
Set this parameter to a larger value for a low-power motor and to a
smaller value for a high-power motor.
If this parameter is set to a too large value, the motor may easily be
overheated and the inverter may suffer over-current.
