Posted 3 Oct 2016 You want someone from this forum to send you a PLC ladder logic program for a MicroLogix 1500 PLC that can control the frequency of a PowerFlex 4M VFD, and this information is to be used for project work while you are on vacation. I suggest you do what most everyone else on this forum has done in the beginning...research the literature A-B/Rockwell has available (possibly they have the program example you desire just waiting for you). Actually, the amount of programming for this is so minimal that a program example is more than needed. Share this post Link to post Share on other sites
