V/fcurvesetting(01-02~01-09and01-12~01-13)
Select any of the predened V/f curves setting ‘0’ to ‘E’ that best matches your application and the load charac-
teristic of your motor, choose a custom curve setting ‘F’ or ‘FF’ to set a custom curve.
Improper V/f curve selection can result in low motor torque or increased current due to excitation.
For low torque or high speed applications, the motor may overheat. Make sure to provide adequate cooling when
operating the motor under these conditions for a longer period of time.
If the automatic torque boost function is enabled (parameter 01-10), the applied motor voltage will automatically
change to provide adequate motor torque during start or operating at low frequency.
CustomV/fCurveSetting:
A custom curve selection allows users to set parameters 01-02 ~ 01-13 whereas a predened curve selection
does not.
