10. Command Functions Related To M of CNC System
and Height Controller

10.1 Function M of Direct Control Output Port of CNC System

M14/M15 switch for rising of cutting gun, M14 (on), M15 (off)
M16/M17 switch for falling of cutting gun, M16 (on), M17 (off)
M38/M39 automatic / manual switch of the height controller M38 (auto) M39 (manual)

10.2 Fixed Cycle of Function M

M07 perforation fixed cycle
The flame cutting operation sequence is as follows:
M07
1. If the gas (acetylene) valve is not opened, then open gas (acetylene) for ignition;
2. The cutting gun falls (cutting gun fall delays, see M71);
3. Open the preheating oxygen valve, the preheating delay starts. If the preheating time is not enough,
you can press the key【pause】, the preheating time is extended to 150 seconds automatically. If the
preheating has been completed, press the key 【start】 to end the preheating delay, and the preheating
time is saved automatically in the preheating delay parameter;
4. The cutting gun rises(perforation cutting gun rise delay, M72);
5. Open the cutting oxygen valve (M12), perforation delay time is delayed, after that the cutting gun
falls (perforation cutting gun falling delay M73);
6. Turn on the height controller (M38); the following procedures start.
The plasma cutting operation sequence is as follows:
M07
1. The cutting gun falls (the falling of cutting gun delays, see M71);
2. If the selected perforation positioning is valid, then the cutting gun falls until it collides with the lower
limit position switch, thus the falling stops; the cutting gun rises, after perforation positioning delay is
delayed, the cutting gun stops;
3.Turn on the starting arc switch;
4. Detect the signal of "arc voltage success", if the arc voltage detection selects 0 in the setting of
parameters (not detected), the arc voltage is not detected. After starting arc succeeds, the perforation
delay is delayed (seconds)
5. Turn on the height controller (M38); the following procedures start.
M08 Close the fixed cycle of cutting
The flame cutting operation sequence is as follows:

SH-HC30 Height Controller System Manual
manual mode of plasma, the height controller carries out the manual starting arc
perforation, after perforation, the cutting gun moves (through the numerical control
system ) for actual cutting, at this time, the value on the nixie tube display of the
height controller is the actual arc voltage of the plasma power supply in the current
environment.
