Scalar Control (V/f)
The factory setting of P0144 (8.0 %) is adequate for standard motors with rated frequency of 60 Hz. When using
a motor with rated frequency (adjusted in P0403) different from 60 Hz, the default value for P0144 may become
inadequate, being able to cause difficulties in the motor starting. A good approximation for the setting of P0144 is
given by the formula:
P0144 =
3 x P0142
P0403
If it is necessary to increase the starting torque, increase gradually the value of P0144.
