Understanding VFD Cables
A variable frequency drive (VFD) is a type of controller that drives a motor by varying the frequency and voltage supplied to the motor. It allows the user to change the speed or output of the motor. VFDs use pulse width modulation (PWD) to control the frequency of the signal and voltage to control motor speed. If you use improper cabling, the high frequency pulses can cause an insulation breakdown .
