Troubles Causes Measures
Link control with
image checker and
code reader fails
The connections with the
image checker or code
reader are inadequate.
• Refer to Setup/Maintenance Guide for the wiring and
communication settings.
• If the Ethernet communication settings or RS-232C usage are
changed, restart the laser marker.
Communication settings are
inadequate.
Marking cannot
be done in an
appropriate position
when the function of
position correction is
used
The coordinates of the image
checker are not consistent
with the marking position of
the laser marker.
Set the calibration of the image checker and match the
coordinate origin of the image checker to the center point of the
marking field of the laser marker.
Settings of the image checker
are inadequate.
Confirm the following settings of PV230/PV200.
• Setting of Ethernet with the protocol General communication
• Calibration
• Settings of the positional correction
• Expression of the numeric calculation
The setting order of the
expression table of PV230/
PV200 is inadequate.
The results of the numerical calculation should output to the laser
marker in the order of X, Y, and theta.
The results of the
code or character
checking is NG.
Testing conditions of image
checker are inadequate. Set appropriate testing conditions of the image checker
according to marked code type or character settings.
Unnecessary objects are
included in the captured
image.
Do not place the code symbols or characters other than the
image checking target in the imaging range.
When PV230 is used:
Settings of the total
judgement are inadequate.
• For code checking, confirm the settings of the code reader
checker of PV230.
• For character checking, confirm the settings of the OCR
checker of PV230.
• Cofirm the expression of the numeric calculation in the total
judgement.
When PV230 is used:
No settings in the character
dictionary of PV230.
To use the character recognition function, set the dictionary of
PV230 for each marking character beforehand.
Ghost image of fumes
(smoke) occurring during
marking is taken in the
shooting range.
• Install a dust collector to get rid of fumes (smoke).
• Check that the dust collector works well.
Marking disorder
Since the work feeding and
marking start/end timing are
inadequate when TIMING IN
signal is used, the vibration
affects marking.
Turn TIMING IN signal ON after work piece is fully stopped.
To feed works after marking, check that TIMING WAIT OUT is
turned ON and start feeding works.
