27.7 On-the-fly marking (LP-RC, LP-RF, LP-RV)
Most problems with on-the-fly marking can be resolved by adjusting the trigger signals, the
workpiece position, or the line speed.
Marking is sometimes skipped (E750)
Cause:
The marking trigger signal is entered before the current marking process
is finished.
Remedy:
• Select multiple trigger mode if you want to input trigger signals during
trigger processing.
• Place the trigger sensor closer to the laser marking system and select
a smaller value for the trigger detecting position.
• Reduce the marking time by increasing the scan speed, for example.
• Reduce the feeder speed.
• Increase the marking interval (interval between the objects on the
feeder).
