    Spindle control Dmm Tech

    Hi everyone i need a little help getting my spindle wired correctly .I am not real good at wiring but i am learning ,i have the motors working with lot's of help . Now i am on to the spindle and the vfd and the forward reverse connections , i got a diagram from Dmm Tech but i am not sure if i am reading it correctly . I will attach the diagram they sent .Question 1 ,in the diagram it seems they are requiring a external supply either 12 or 24 volt what is the resistor doing . Question 2, is the line with the resistor positive Volts on D16/D17 And S16 And 17 negative ? Thanks
