Galvano Scanner - Panasonic VL-W1-N Series Setup And Maintenance Manual

9.
Click "STOP" to stop laser radiation.
10.
Check the measurement results of the power
meter. If the power decays lower than the initial
status, correct the laser power setting value
using the "System Offset" parameter of the
"Environment Setting" screen.
Setting range of laser power correction: 50 to 200 [%]
Example:
If the measured power is 35W though the setting power
is 36W (about 3% lower than the expected power), set
the system offset to 103%. It increases the laser power
setting 3% above the current settings internally in all files.
• If the power decays more than 20%, compared to the initial status, the laser oscillator needs maintenance. Contact our
sales office or representatives.
• If the corrected value exceeds the upper limit of the setting, the corrected value is the same as the upper limit.

7-2-8 Galvano scanner

Galvano scanner is a scanner for radiating the laser beam along the coordinates of the setting data.
The galvano scanner scans the setting data by controlling the angle of galvano mirror mounted onto the axis of rotation of
motor with two axes to create drawings for the laser processing.
„ Effect from deterioration
Uneven wear may occur on the bearing inside the galvano scanner depending upon operating frequency and conditions. If
uneven wear develops, accurate reproducing may become difficult, resulting in skewness or misalignment of the drawing
lines.
„ Replacement interval
• Deterioration in quality of the drawing lines, misalignment of lasing position, or incomplete processing is observed.
• Warning for galvanometer error occurred.
• Galvano scanner has been used for almost five years.*
* The replacement interval may differ depending on the usage environment and conditions.
„ Replacement method
Our service representative handles the maintenance and replacement. Contact our sales office.
