Breakpoints and High-Speed Capture with Open-Loop Steppers Hardware: Motion Control>>Controllers
Problem: I want to do some triggering based on the position of my stepper motor. Can I use breakpoints or high-speed capture if it is open-loop and doesn't use feedback sensors? Solution: No, since timing and triggering with NI-Motion is always related to position or velocity, you must receive feedback information in closed-loop mode to generate breakpoints or do high-speed captures. If you need to synchronize a process to your move with an open-loop stepper, the step output signal of the NI Motion controller can be used as the synchronization signal.
