Controlling Timing of Judgment with Triggers
Internal trigger
When the [Trigger Options] is set to [Internal], imaging and judgment are performed at the timing of set
trigger interval.

(1) Inputs internal trigger in the trigger interval being set.
(2) BUSY output function turns ON at the timing that internal trigger occurred. Processing time differs
depending on the settings.
(3) The target is imaged and judged. No trigger delay settings.
(4) After the judgment process is completed, it updates status output and the BUSY output function is
turned OFF. Confirms that the BUSY output is turned OFF, then imports the status output.
(5) If the internal trigger is input while the BUSY is being output, the input is ignored and a trigger error
occurs. Trigger 3 is not judged. To output the trigger error, set the trigger error within the Output
Assignment (Page 4-60) under Settings Navigator to [ON].
y The ON status of each output is as follows.
When Output Settings (Page 6-27) are [N.O.] : Status with NPN or PNP open collector ON.
When Output Settings (Page 6-27) are [N.C.] : Status with NPN or PNP open collector OFF.
y The trigger error output function turns OFF when the next trigger is activated, when the error is cleared,
when the program is switched, or when the system moves to the settings screen.
y When the output mode (Page 6-27) of status output is set to [Latching]. When the output mode is set to
[One-Shot], refer to “Changing the timing of the status output” (Page 7-6).
Set the trigger interval longer than the processing time. If the trigger interval is shorter than the processing
time, the internal trigger will be input during the processing time, so the trigger error will occur.
Operating in the shortest cycle
To input the internal trigger in the shortest cycle and perform the judgment process, set the trigger input to
1 ms. Also, set the trigger error in the Output Assignment of Settings Navigator (Page 4-60) to [OFF] and
ignore the trigger error.
