A report by Rockwell automation, which is mildly related https://literature.r...wp014_-en-p.pdf
A motion controller can control multiple axis with extreme accuracy. If you are using flying shears or rotating knifes with a motion controller why would you need to stop start and use a dancing arm to maintain tension.
PID is probably not a good idea in this application, PID is more suitable for process control.
because I am not using flying shears or rotating knives. the web needs to stop to be sealed, then drawn and stopped again for the next bag to be sealed.
This document is very helpful and relevant to me. Thanks for that. .
