4. Common M instructions
1) Common M instructions:
Users only need to know the functions of M07, M08, and M02 instructions. M07 refers to fixed cycle of
preheating and perforating. When the track is processed and come to perform M08, the system will close all
related valves. In the end, perform M02 to finish the processing. Detailed functions of codes are as follows:
M07 Fixed cycle of preheating and perforating, operating sequence is as follows:
Flame:
1. Open acetylene valve; M10
2. Ignition on; M20
3. Drop the cutting gun; M16
4. Open the preheating valve and start preheating; M24
5. Lift the perforating cutting gun; M14
6. Open cutting oxygen valve; M12
7. Drop the perforating cutting gun; M16
8. Perforation complete, and go to the next motion.
Plasma:
A). with height-adjusting system:
c Enable M22
d Arcing M12
e Waiting for arc voltage detection signal (IN0)
After arcing, the height-adjusting control starts performing initial location (With height adjustor for
initial positioning, at this time the initial positioning in parameter is disabled), perforating and
perforating delay automatically, and gives a signal of successful arc voltage detection to the
controller. The control system begins the next motion when it detects the arc voltage signal.
B). without height-adjusting system and initial positioning:
1. Arcing, arcing delay M12
2. Perforating, perforating delay
3. Cutting gun falls
4. Start cutting
M08 Close the cutting fixed cycle. The operating sequence is as follows:
