・ Processing mode change during beam output
In the setting screen, processing mode can be changed even if during automatic
operation or laser output by manual operation. But laser beam can’t be outputted
at that time because laser oscillation is stopped and restarted automatically by
CNC to change laser gas. And laser alarm happens by stopping the oscillation.
Laser gas change function is interrupted when laser alarm happens. So, laser
sequence is not restarted automatically by CNC even if alarm is released. In this
case, please turn on signal RUN or HVON as normal laser start-up to restart
laser sequence by manual.
Changing the processing mode during laser beam output is not recommended in
conclusion.
・ Display of mode change
The message “GAS CHG” blinks in the lower right-hand of CNC screen when
laser gas change sequence is started automatically by CNC to change the
processing mode.
When processing mode is changed during power calibration, power calibration
function is re-executed after laser gas change sequence is started. In this case,
message “PWR CLB” blinks because power calibration is executed even if during
processing mode change.
・ Power calibration
In case of processing mode is changed when laser oscillator is in oscillation state
(LSTR=1), laser oscillation is stopped and laser sequence is restarted up
automatically. But power calibration is not executed again.
・ Power calibration coefficient
A same value of power calibration coefficient is set to parameter No.15204 for
High power mode and parameter No.29020 for Fine mode automatically by CNC
when laser oscillator is started according to set processing mode and power
calibration function is executed.
If you change the power calibration coefficient value of each processing mode by
manual operation during laser oscillator is in oscillation state(LSTR=1), laser
oscillator output laser beam with the changed power calibration coefficient.
・Automatic aging function setting screen
In the automatic aging function, the parameters that are used for the function
are changed to those for High power mode or for Fine mode by processing mode
