SECTION 9
If the shutter speed does not meet the following conditions, image motion will have a negative effect
on reading.
To set a minimum shutter speed to read moving workpieces, perform teaching after set-
ting the lower limit of the shutter speed under System Set./Camera/Lighting .

Reading Time
The reading time can be calculated using the following formula.
The 2D Code Checker can be displayed to check the reading time on the screen.
The time displayed by the 2D Code Checker, however, includes processing time, so the
time will be longer than normal.
If the reading time does not satisfy this equation, the code will not be in the field of
vision even if the speed code satisfies conditions, and reading will not be possible.
Example: For a line speed of 60 mm/s and a code interval of 30 mm
Thus, reading will not be possible unless the reading time is 500 ms or less.
If the reading time is longer than 500 ms, then either the line speed will need to be
reduced or the code interval will need to be increased.
