Inspection Results and Output
13.4
Judgment Output
NG Operation
When a "NG" result is generated in a Judgment register (i.e. the conditions were not
satisfied) you can execute one of the two functions described below (Trap or NG
Display). Each product type can only be set in one register, and if you execute a data
save, the settings will be stored even if the power is switched off.
1.
Trap function (T)
If you execute an inspection from the main menu and a judgment register that has
a trap set for it becomes NG, the execution depends on the following two settings.
(1) When the Trap function is set by the judgment, the READY signal is held at
the OFF level even after inspection is finished, and the following message is
displayed. Because the READY signal is off, the START signal is not
accepted, and the next inspection is not performed.
At this time, the only way to return (to the state where the next inspection
can be performed) is to press B.
(2) If Save Image Data in the Environment menu is also set for the Trap function
in addition to the settings for (1), the memory image at the time the NG occurs
is stored.
See 15.1 Loading and Saving Image Data for details.
Unlike (1), the READY signal stays on, so it is possible to continue performing
inspections after a NG is generated.
2.
NG Display function
If you execute an inspection from the main menu and (when the result of the
specified judgment output is NG), this function just displays the image. This is done
if you have set an N (NG indicator) in the judgment register, and Gray NG for the
display image.
This cannot be used when the capture camera is set to AB.
When the conditions for a judgment register that has an N (NG Display) set for it
become NG, the image is displayed on the monitor, and, subsequently, the monitor
display image is only updated when another NG occurs (i.e. the current NG image
is displayed until the next NG occurs under the same register conditions). The
monitor only displays the NG image, and inspections are executed on a new
image.
