 Line speed
If the object moves while the image is being loaded after the shutter is released, the image will be
blurred. Fix the speed of the line by taking factors such as the shutter speed (which can be
changed in the setting menu), the cell size for the object, and the field of vision of the camera into
account.
 Tact time
A certain interval is necessary between reading objects during which the next trigger signal is not
input. This interval (time) is called Tact Time.
Example: Processing time for reading: 500 ms; Line speed: 30 m/min.
The distance moved in 500 ms is 0.25 m. Therefore, an interval allowing 0.25 m min. of move-
ment is necessary.
 Number of retries
If reading is NG, reading continues to be performed for the number of retries specified by the set-
ting conditions. When reading moving objects, reading may continue after the object has left the
field of vision.
Refer to page 112 (Sec.5).
 Level Trigger Reading
For timing input, use TRIG B, TRIG C, and TRIG D.
Regardless of the displayed image (through/freeze), a 33.3 ms max. delay occurs before loading
the image after a TRIG signal is input.
If the line speed is too high...
The object has already passed,
the image is blurred and cannot
be read.
