I am currently trying to find a way to match the speeds of two machines with each other. One machine has a two speed AC motor with a variable
speed pulley. The other machine is ran with an AC frequency drive using an external pot. Am I correct to assume that the easiest way to
match the speeds is to use an encoder on the two speed AC machine going to a PLC w/high speed counter and then drive the 4-20 ma input on
the frequency drive? Any help would be highly appriciated.
