ASK THE EXPERTS
I am finding nothing to solve my issue on any site or publication, maybe you can help. I have a screw running on a stepper motor and am trying to determine the distance for the Light Curtain or does it matter when using a Stepper motor as the stop is instantaneous? There is no 90 deg stop time like on a cam run machine or gear driven. I am writing up a Guarding program for my company and want to include this information. Any ideas?

The safety distance will depend on the overall response time of the sensing device and control system including any communication delays for remote I/O as well as the mechanical stopping time of your screw, however small that may be.
