The figure shows the sequence of execution of the above
commands and the occurrence of registration events when you use
inclusive windowing.
There are delays between these events:
• Trajexia receives the latch.
• Trajexia decides to trigger the latch again.
• The latch is triggered.
Because of these delays, there is an uncertainty in the edges of the
window when marks may be detected near the edges. This is more
notable for axes connected to the system via the
MECHATROLINK-II bus due to bus delays. To compensate for
these delays, a user must set the window margins large enough.
