27 Troubleshooting
E618 Cause:
The workpiece spacing is too small.
Remedy:
• For marking at regular intervals, increase the workpiece spacing.
• For multiple trigger mode, increase the time between trigger signals.
• Decrease the line speed.
• Specify an upstream position (positive value) for the lasing start
boundary.
• For multiple trigger mode, make sure the switch or the sensor
connected to TRIGGER IN (X5) of the TERMINAL connector
operates without chattering.
• Reduce the marking time by increasing the scan speed, reducing the
space between characters, reducing the character size, reducing the
ON-time for one-shot outputs, etc.
Applies to LP-RC, LP-RF, LP-RV only.
E619 Cause:
On-the-fly marking is not possible with the set trigger detecting position
or lasing start boundary.
Remedy:
• Place the lasing start boundary downstream of the trigger detecting
position.
• Check the setting of the workpiece reference boundary.
Applies to LP-RC, LP-RF, LP-RV only.
E620–E621
Cause:
The processing in the laser marking system could not be completed.
Marking trigger processing terminated abnormally.(Applies to the linking
