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.
Buffered Breakpoints (NI 7350 only)
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.
