Troubles
Causes
Measures
Character is partially
chipped.
Obstacle hinders laser beam.
Remove obstacle between head of laser marker
and object.
Laser emission port is not clean.
Refer to the “Safety / Setup / Maintenance Guide”
“Maintenance” and clean contaminants off the
laser emission port.
If contaminants persist, replace lens and/or
protection glass of laser emission port.
Contact our sales office.
Marking is dotted.
For LP-Mxxx / LP-Sxxx / LP-Zxxx:
Setting of laser pulse cycle and scan
speed are inadequate.
Decrease scan speed or marking pulse interval.
Marking line runs over
the intended start or end
points.
The setting in marking quality
adjustment parameter does not match
the other marking conditions.
Input the suitable adjustment value in marking
quality parameters such as start point, end point,
or wait value in laser setting screen.
Marking disorder
(Characters crushed,
unreadable)
The Fixing strength of the laser marker
head is insufficient.
• Fix the head part tightly with the specified
torque value.
•
Improve the strength of the stand on that the
head is installed.
There are continuous vibrations coming
from surrounding equipment such as
motor and press.
Perform vibration prevention measures.
There are irregular vibrations coming
from surrounding equipment such as
air cylinder and forklift.
Start and/or stop timing of feeder does
not match with marking operation.
(Marking is disturbed at beginning/end
of marking.)
•
When disturbed at the beginning of marking:
Marking trigger signal is likely to be entered
before object is fully stopped. Marking may
disturbed due to remaining vibration even
if object is in full stop. Use delay timer etc.
so that marking trigger signal turns on after
vibrations are completely damped.
•
When disturbed at the end of marking:
Object is likely to start moving before
completion of marking. Delay start timing of
feeder or decrease scan speed so that marking
is finished before object starts moving.
There are noises coming from
surrounding equipment.
Protect laser marker against noises as follows:
•
Securely ground frame ground terminal of laser
marker or surrounding equipment.
•
Isolate power and signal lines from each other
if they have been routed in parallel.
•
Shield signal line.
•
Isolate power supply for laser marker from
other equipment.
•
Use noise cut transformer to absorb noises
from power supply.
