Galvano Scanner - Panasonic LP-GS Series Setup & Maintenance Manual

8.
Check the measurement results of the power meter. If the
power decays lower than the default setting, correct the
laser power setting value using the "System offset" panel of
the "System settings" screen.
Setting range of laser power correction: 50 to 200 [%]
• Laser power correction refers to the function to correct not the maximum
laser power [W] value but the laser power setting value.
• If the power decays more than 20%, compared to the default setting, the laser oscillator needs maintenance. Contact our
sales office or representatives.

7-2-6 Galvano scanner

Galvano scanner is a scanner for radiating the laser beam along the coordinates of marking data.
The galvano scanner scans the drawing data by controlling the angle of galvano mirror mounted onto the axis of rotation of
motor with two axes to create characters and graphics for marking and processing.
„ Effect from deterioration
Uneven wear may occur on the bearing inside the galvano scanner depending upon marking frequency and conditions. If
uneven wear develops, accurate reproducing may become difficult, resulting in skewness or misalignment of marking lines.
„ Replacement interval
• Deterioration in quality of marking and processing (Characters crushed, streaking and density reduction of the marking,
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 marking conditions.
