Buffered Breakpoints (Ni 7350 Only) - National Instruments NI-Motion User Manual

All breakpoints can be affected by jitter in the motion control system. For example,
Note
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.

Instead of enabling breakpoints in your application at the software level,
you can create a buffer of breakpoints that you can pre-load into the motion
controller. The motion controller automatically arms the next breakpoint in
the buffer when the preceding breakpoint triggers. Therefore, enabling
breakpoints occurs on a firmware-timed basis, which enables you to use a
higher bandwidth.
