Periodically Occurring Breakpoints
NI-Motion allows you to program the motion controller to generate multiple breakpoints at fixed and exact intervals, regardless of the direction of travel or velocity.
There are two ways to create periodically occurring breakpoints using NI-Motion functions, depending on which motion controller you have. For the NI 7350 controller, use periodic breakpoints. For NI 7330, NI 7340, and NI 7390 controllers, use modulo breakpoints .

Note All breakpoints can be affected by jitter in the motion control system. For example, if you have a very small breakpoint window, the jitter in the motion control system could cause the position to change enough to reach the breakpoint when a breakpoint is not intended. Increase the size of the breakpoint window to compensate for system jitter. |
