Figure 4.3.12 V/F curve defined by users
‧ Set the V / F curve based on the allowed load characteristic of the motor. In the
application of low torque and high speed, the motor may overheat. If the motor
operates under this condition for long time, you have to pay special attention to the
motor cooling.
‧ If the automatic torque boosting function is started by parameter 01-10, starting and
operating under the condition of low frequency, the motor voltage will automatically
change to provide adequate motor torque.
