Using VFD eliminates this voltage sag, since the motor is started at zero voltage and ramped up. Lower Power Demand on Start. If power is proportional to current-times-voltage, then power needed to start an AC motor across the line is significantly higher than with a VFD. This will be true only at the start up.

The difference with Soft Starter vs Variable Frequency Drive (VFD) is the method of starting employed. A soft starter reduces voltage, not Hertz, and as such the starting torque at 2-3 Hz is next to nothing. The soft starter is essentially robbing the motor of voltage at all points between 0 and 59 Hz, peak (Line) voltage met at 60 Hz.
