4.1.2 Inspection Time

Inspection time refers to the total time required for the following four inspections.

Measurement
Internal trigger: ON
At least 30ms is required for inspection.
(If the inspection time exceeds 30ms, it will become equal to the one required for internal trigger OFF.)
For example, if exposure time for Color Judgement = 5 ms,
Internal Inspection
trigger time
OFF 19 ms
ON 30 ms
•
Computation time for Color Pattern Matching slightly differs depending on the measurement
condition and inspection position. The conditions of computation time above is as follows:
Template size: 64 x 48 pixels
•
After changing product types, it takes approximately 50ms longer than normal inspection time for
the first inspection.
•
If you execute inspection monitoring images and measurement results with AETOOL, it takes 0.6
to 1.2 second longer than the inspection time shown in the table above.
0.03 - 50.00 ms, set the exposure time in TEACHING mode

Explanation
= Computation time (10) + exposure time (5) + transmission time (4)
If the total time is less than 30ms when internal trigger is ON, the
device is forced to wait until 30ms.
