Cause:
There are irregular vibrations coming from surrounding equipment, such
as air cylinders and forklifts.
Remedy:
Take measures to prevent vibration.
Cause:
The starting and/or stopping of the workpiece feeder does not match the
marking process.
Remedy:
• The marking process is disturbed at the beginning: The marking
trigger signal is input before the workpiece has fully stopped or the
equipment continues to vibrate after the workpiece has stopped. Use
a delay timer, for example, to input the trigger signal only after no
more vibrations occur.
• The marking process is disturbed at the end: The workpiece starts
moving before the marking process is completed. Delay the start
time of the workpiece feeder or increase the scan speed so that the
marking process is finished before the workpiece starts moving.
Cause:
Surrounding equipment produces noise.
Remedy:
• Securely ground the frame ground (FG) of the laser marking system
or the surrounding equipment.
• Insulate the power and signal lines from each other if they have been
routed in parallel.
• Shield the signal line.
• Insulate the power supply of the laser marking system from other
equipment.
• Use a noise cut-off transformer to absorb noises from the power
supply.
Marking line runs over the intended start or end points
Cause:
The fine adjustment parameters in the laser settings do not match the
other settings.
Remedy:
Adjust the laser settings such as start point, end point, or waiting time.
