How do you connect a VFD with R S T to 220 power single phase?

The below information is for your convenience; however, please seek the guidance of a professional electrician that is experienced with VFDs and electrical motors of this type. A VFD (Variable Frequency Drive) for CNC Spindles that have input terminals labeled R, S and T will typically use the R and T for the Black (live) and White (neutral) connections and the PE (protective earth) will connect to ground (green). Check this image for reference: https://www.buildyourcnc.com/images/SpindleWiring-800.JPG With the YL600-2S VFD, we have found that the R and S terminals are used where the R is live and S is neutral. Connect the PE to the green ground connection. Additional Information:
