I don't know how your positioner is set up but using inches per minute may not be the way to go.
When you spin something in A circle the closer to the center you are, the faster it spins.
Both near the center and farthest edge of A disk both travel 360 degrees when rotated one complete
cycle. The farthest away travels much farther than the center. Try changing point to J 100 % fine for the positioner. Then adjust your travel with the % value. Surely some trial and error will occur, don't be afraid to make drastic changes in the % value when you start, will get the results you need faster.
Positioner needs to spin at in/min per customer requirement's for weld speed unit type. I figure that's why Coordinated Motion may need to be used...because that would then tell the positioner how fast to spin compared to Robot TCP. It's just a slightly messy way of taking care of my welding situation since the same weld job is used in different positions along a 2000m rail...So I'd either have to write a weld job per each position (200+ of the same program) or write 1 job with an indirect PR...but that's where the Coordinated Motion gets messy and why I am hoping to avoid Coordinated Motion, but it's looking like my ONLY option right now.
EDIT: Oh and I can't use Joint % because that is not in IPM for the customer's quality database.
