6 NC system associated with adjustable block M instructions
6.1 M function of NC system to control the output port directly
M12 / M13 start arc switch, M12 (open), M13 (close)
M14 / M15 cutting torch rises switch, M14 (open), M15 (close)
M16 / M17 cutting torch switch, M16 (open), M17 (close)
M38 / M39 adjustable block automatic/manual mode switch M38 (automatic)
M39 (manual)
6.2 M function fixed cycle
M07 perforation fixed cycle
Plasma cutting operation sequence is as follows:
M07:
1. The cutting torch fell (cutting torch down latency, see M71).
2. Open the arc switch.
3. If the parameter setting is in the arc pressure detection from 0
(no), there is no any arc pressure, delayed perforation delay
(seconds).
4. If the parameter is set in the arc pressure detection choose 1
(testing) arc pressure measurement, waiting for the starting arc
"success".
5. Delay "higher automatic delay".
6. Open the block (M38), began to run after the program.
M08 close cut fixed circulating
Plasma cutting operation sequence is as follows:
M08
1. Shut down the block (M39).
2. Close the arc pressure switch.
