4.Signal
- Oscillator start signal
RUN<G222#6>
[Classification] Input signal
[Function] This signal starts or stops the oscillator.
[Operation] Starting the oscillator
When the oscillator start signal (RUN) is set to 1 with the purge completion
signal (PURGE) set to 1, the CNC starts gas pressure control, set the purge
completion signal (PURGE) to 0, and sets the oscillator ready signal (WAIT) to 1.
Stopping the oscillator
When the oscillator start signal (RUN) is set to 0 during operation, if discharge is
being performed, the CNC stops discharge. If discharge is not being performed,
the CNC immediately closes the laser gas supply valve, and opens the exhaust
valve to evacuate the fan system for the period specified in parameter No.15226.
At this time, the discharge start ready signal (LRDY) is set to 0, and the oscillator
ready signal (WAIT) is set to 1.
Upon the completion of evacuation, the CNC starts purge processing to supply
new laser gas, up to atmospheric pressure. Once purge processing has been
completed, the oscillator ready signal (WAIT) is set to 0, and the purge completion
signal (PURGE) is set to 1.
- Discharge start signal
HVON<G222#7>
[Classification] Input signal
[Function] This signal starts discharge for the oscillator, thus readying the oscillator for
operation.
[Operation] When starting the oscillator
When the discharge start signal (HVON) is set to 1 while the discharge start
ready signal (LRDY) is set to 1, the CNC turns on the laser power supply to
achieve the reference discharge state.
When stopping the oscillator
When the discharge start signal (HVON) is set to 0 while the oscillator is
operating, the CNC turns off the laser power supply to stop discharge, and set
the discharge start ready signal (LRDY) to 1.
