Trigger Out Position Steps
Note
If the trigger mode is not set to one of the three position modes described
previously, then the following parameters are not applicable and will be
hidden.
As soon as a position triggering mode is selected on either of the TRIG ports, the port
will assert the inactive logic state, set in the Trigger Polarity parameters.
As the stage moves in its travel range and the actual position matches the position set
in the Trigger Start Position parameter, the TRIG port will output its active logic state.
The active state will be output for the length of time specified by the Trigger Pulse
Width parameter, then return to its inactive state and schedule the next position
trigger point at the Trigger Start Position value plus the value set in Trigger Interval
parameter.
Thus when this second position is reached, the TRIG output will be asserted to its
active state again. The sequence is repeated the number of times set in the Trigger
Count parameter.
When the number of pulses set in the Trigger Count parameter has been generated,
the trigger engine will schedule the next position to occur at the position specified in
the Reverse Trigger Start Position parameter. The same sequence as the forward
direction is now repeated in reverse, except that the Reverse setting parameters
apply. When the number of pulses has been output, the entire forward-reverse
sequence will repeat the number of times specified by Trigger Cycle Count
