[/INST] You need to give us a lot more information for us to help. The best thing you can do right now is upload your PLC's ACD file for us to look at. It's most likely an axis configuration problem of some sort. It doesn't make sense for us to guess at it; uploading the ACD will get you a good answer rapidly. \\n </s>
