Question Answer
Can I turn LED light emission of the Sensor
Head OFF?
Yes, you can.
[CUSTM]-[Set LIGHT] to [0000].
p.71
What should I do to set the measurement
time as short as possible?
There are two ways of setting a shorter measurement time:
• [Set CUSTM]-[IMAGE RATE] to [HIGH SPEED]. Note, however,
that image processing becomes rougher, and measurement
accuracy drops.
p.61
• Switch the screen display during measurement to “Display only
image”.
The measurement time can be reduced proportionate to the
reduction in display time.
p.59
Teaching is not going well. What should I
do?
• Workpiece move teaching mode
A probable cause is that the workpiece is not properly in the
teaching area as intended.
Change to the workpiece stop teaching mode or teaching by key
operation.
• A probable cause is that teaching is not successful because an
image is too dark or too bright.
Adjust light emission at [CUSTM]-[LIGHT] so that the workpiece
is projected clearly, and execute teaching again.
p.71
• Does it switch to the teaching area MOVE (move) screen or
SIZE (Resize) screen?
Teaching cannot be performed from the MOVE screen or SIZE
screen. Set the position or size with the SET key, go back 1
screen up then press the teaching button.
At what timing are set measurement condi-
tions saved to the amplifier unit?
Set measurement conditions are saved to the amplifier unit "when
external TEACH signal teaching is successful" or "when switched
to RUN mode."
When the TEACH key is pressed from the teaching screen to
teach, contents will not be saved unless switched to RUN mode
once. Changed contents, including teaching results, are cleared
when switching off without saving.
Even though I change the search area for
SEARCH/MATCH, the search is done out-
side the search area.
If the CUSTM setting has been changed, perform the teaching
again.
