NOT KNOWN FACTUAL STATEMENTS ABOUT VFD CONTROL PANEL

But, if we reduce the frequency to 30Hz, then we have to also lessen the voltage to 240V to be able to manage the V/Hz ratio. How are we going to decrease the voltage if the sole voltage Now we have is 650VDC?AC motor velocity is controlled in two methods – both by controlling the voltage or frequency. Frequency controlling provides superior cont
