Causes
• 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.
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.
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 results of the numerical calculation should output to the laser
marker in the order of X, Y, and theta.
Set appropriate testing conditions of the image checker
according to marked code type or character settings.
Do not place the code symbols or characters other than the
image checking target in the imaging range.
• 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.
To use the character recognition function, set the dictionary of
PV230 for each marking character beforehand.
• Install a dust collector to get rid of fumes (smoke).
• Check that the dust collector works well.
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.
