Basically VFDs do not increase output voltage: if the input is 230V, the output max will be the same (this is why we have star or delta connection on the motors).
5:30 this is what we call V/f curve. For really you can adjust it, f.e. make higher voltage at low frequency.
6:20 for really it generates pulses (PWM), not SINUS wave. When you connect the motor, you get SIN wave, because motor is inductive load 😉

Super super ,wonderful sir .this is what have been waiting for .thankyou.

Thanks and welcome

When the potentionmetre is at the lowest point let say zero, the multimetre reads 50hz. When you vary the potentiometre the frequency on the multimetre increases up to 300 before we can obtain a voltage of 220V. Will the motor that is mean to fonction at 50Hz not be damage ??

Hey David, would you kindly show us how to set the parameters(using the user manual) of the VFD specifically to control a submersible pump ?.. please consider that.

Iam not Understand what is ur explained it Genarate 1-Phase to 3-Phase

[@sankarreddyelectricals898]

Give me reply Send ur Contact Number

[@electreca1]

Yes, it coverts single phase to 3phase.
