8.6.5 Status Output Signals
(1) Purge completion signal
This signal is issued, when the unit is switched on, and the CNC
starts operating. When this signal is issued, the RUN signal
becomes acceptable. When the RUN signal is turned off, purge
processing occurs to purge the gas from the discharge tube.
When purge processing is completed, the purge completion
signal is sent out. After it is sent out, it becomes possible to
switch off the power.
(2) Oscillator ready signal
This signal is issued when laser gas pressure control begins in
response to the RUN signal. When the RUN signal is turned off,
purge processing begins. It is kept on until purge processing is
completed.
(3) Discharge start ready signal
This signal is issued when gas pressure control ends.
(4) Reference discharge start signal
This signal is issued when reference discharge control begins in
response to the HVON signal.
(5) Oscillator signal
This signal is issued when reference discharge begins.
Laser machining is possible while this signal is on.
(6) Mode output signal
This signal indicates whether the laser output is continuous or
pulsating.
(7) Beam output signal
This signal is issued, when the shutter is open, and the laser
beam is radiated to the outside.
(8) Tracing motion signal
This signal is issued, when the tracing function starts, and the
nozzle has approached the workpiece, then an approach
completed state is detected. When the tracing function is
disabled, the signal is turned off.
