8.6 STATUS OUTPUT SIGNAL
8.6.1 Piercing Signal
For the C and Y series oscillators, if G24 is executed to specify
piercing, the piercing signal is output when piercing is being carried
out.
8.6.2 Laser Processing Signal
For the C and Y series oscillators, the laser processing signal is turned
on at the beginning of assist gas output, and stays on until tracing
control ends.
G32 command
G14 command
Laser processing signal
8.6.3 Output Drop Alarm Signal
If the oscillator mirror gets dirty, the laser output drops.
When the laser oscillator starts up, a power compensation factor is
calculated automatically and used to compensate the laser output for a
drop that occurs due to a dirty mirror. However, compensation has a
lower limit to a drop in the output. If the output drops so badly that
the required compensation exceeds the allowable level, an alarm is
indicated on the CRT screen, and the output drop alarm signal is
issued.
Pressing the reset button clears the alarm indication on the CRT
screen, but does not clear the output drop alarm signal.
This signal is kept on until the mirror is cleaned to resume the initial
output level.
