Kollmorgen AKD series

In these events, the precondition logic samples the current (post-filter) state of the selected precondition source
input. The capture engine looks for a trigger edge while the precondition input is at a “1” or “0” state.

Event 1 (Trigger edge after precondition)
In this event, each trigger event requires Enable=1, a new precondition edge, followed by a new trigger edge. The
sequence requirements are shown in the figure below.
