Are you talking about the SHM_continuous.vi? This vi will stop whenever an error occurrs. Anyway - you should always react in your software on events like hitting a limit switch. You should use the "Read per Axis Status.flx" vi to find out that a limit switch was hit.

My programme is not the same as this one but equal mostly.As u know this programme is while loop with high speed.I consider thought i react in software the loop must stop,but that is not allow in my system.
moreover plus too nod in while loop will reduce the loop speed.Is there anyother method i can try?
thanks!
