    Position lost with CanOpen controlling Schneider drive

    OMG! Looks like P7-01 did the trick! thank you so very much! Youre great, I got to admit it I hope it will keep on this way, the testing period was short.

    Position lost with CanOpen controlling Schneider drive

    About the home reset, this button is simply a patch for this problem, so when the position was lost, and the drive still saying the home was good, se coule manually reset every home with this button. Node 12 isnt there because it wasnt convinient for our specific project. Overall, we rarely user this button. Thank you kratmel for your input :)

    Position lost with CanOpen controlling Schneider drive

    uhThanx for your reply, Aus on other projects, we were working with only one drive. For the current project, we have 4 drives. We use the same code (with different bits et node numbers for each drive, obvioulsy) and 2 drives loose their position 40% of the times when we switch them on. So, it aint all the time, it's intermittent. We haven't been able to see a pattern (like tring to switch them on while they're moving). Theese drive never worked well together. But on previous projects, we were using the same bloc of code, the same hardware (but only one drive) Thanx for thinking about it!
  5. Hi, Please, We're controlling four LXM28AU07M3X (Lexium 28) Schneider drive at the same time. For years, with only one drive, we got no problem. But now, when "Switching On" the drive, we sometimes loose the current position. We end up with a small negative value (we think it's the portion of a motor turn the encoder reads). We tried with Schneider, with no success. Anyone here can send us an example of code to start the drive, trough CanOpen? Anyone had similar issues? We wonder if a filter on the power lines will fix it. We'll try it next week. Here is our code, if anyone wonder. Thank you all scie automatique 328.vlp
