„ Moving objects
• The on-the-fly marking is not available to LP-GS series.
Troubles
Marking is sometimes
skipped.
(E750 occurs.)
The start lines of the
characters are distorted.
Characters are distorted.
Character pitch is
unstable.
Causes
Marking trigger signal is entered
before current marking is
finished.
The timing of lasing does not
match with the line speed.
The setting of the moving
direction is wrong.
Speed changes at conveyor
junction.
Actual speed and preset speed
for feeding objects are different
due to slippage of objects.
Positional misalignment is likely
to occur due to meandering
motion of conveyor.
The moving speed of the
conveyor is not stable.
When Line speed control is set
to Fixed speed:
The setting speed is not
consistent with the actual line
speed.

Measures
• Set the trigger mode to Multiple triggers if you want
to input next triggers while the trigger processing
operation.
• Place the trigger sensor closer to the laser marker and
set the smaller value to Trigger detecting position.
• Reduce the marking time with the measures such as
increasing the scan speed and etc.
• Reduce feeder speed.
• Increase marking interval (interval between objects on
feeder).
Input larger value to Overrun correction.
• Match feed direction with laser marker operation.
• Check the setting direction of the laser head of the
system settings screen.
If conveyors are coupled, avoid marking near conveyor
junction.
Remove cause of object slippage.
Secure objects to prevent misalignment.
• Check the conveyor and remove the cause of the
speed change.
• To keep up the conveyor speed, use encoder to
feedback the change of the speed.
Adjust the setting value of the line speed by checking the
marking quality.
• When the Character Spacing is too wide:
Increase the setting.
• When the character spacing is too narrow:
Decrease the setting.
