Best approach to hold the feed depending on signal input

Hi,

What is the best way to hold the feed depending on a sensor output? (could it be the same as an external pause/resume button?)
You can imagine it as a knife or stamp hitting the material being fed, the event happens about 600 times per second.

Thank you.
