frequency. When standard AC motor is used, it corresponds to the motor rated voltage. Refer to motor
nameplate.

The basic operating frequency f
voltage of the inverter. When standard AC motor is used, it corresponds to the rated frequency of the
motor. Refer to the motor nameplate.
P0.16
Effect of the torque boost function: when the inverter operation at low−frequency, increase the output
voltage, and offset the stator voltage drop to product enough torque, so as to ensure the normal
operation of the motor.
Note:
The torque boost amplitude should be set according to the load situation. Excessive boost will
cause large current impact during the startup process.
When P0.16 is set to 0.0, and P4.00 is set to 0 (linear V/F curve), the automatic torque boost is
enabled; when P4.00 is set to a non−zero value, the automatic torque boost is disabled.
