Hello all,
I seem to have exhausted the limits of my knowledge, thought I might give yours a try. I've got a machine that wraps hose before the vulcanizing process. I've got 2 reel-ups to gather the hose onto reels. I take the speed of the wrapper, and calculate how fast I need the reel-up to go to keep up. I send the same speed reference to both reel-ups. Only the one I'm using gets the "start" signal. Every once in a while, (maybe 3 times a shift...) The same reel-up will not start when the operator starts the machine. The drive will say "running at speed." "0 RPM". The operator can push the stop and start button to re-start, and it will pick up and run like nothing happened. I've got 6 of these machines with the same program, and I don't have this issue anywhere else, so I don't think it's my programming. I've swapped drives to see if I can move the problem. It didn't move. I've tried new ethernet cables, and different ports. I've checked and double checked parameters in the drive. Of course, when I'm online the machine runs with no problems. I'm not sure where else to look.
Thanks in advance for your help!
