6.4. M Auxiliary Commands
M00
Program suspension
command. The program execution will be suspended at this command until
[START] key is pressed.
M02
Program end
command. The program will be pended at this command.
M30 The same as M02.
M10/M11
Acetylene(GAS)
valve switch commands, M10 to open and M11 to close the valve.
M12/M13
Cutting oxygen valve
switch commands, M12 to open and M13 to close the valve.
M14/M15
Cutting torch lift
switch commands, M14 to turn on and M15 to turn off.
M16/M17
Cutting torch lower
switch commands, M16 to turn on and M17 to turn off.
M24/M25 Reserved switch commands, M24 to turn on and M25 to turn off.
M20/M21 Ignition switch commands, M20 to turn on and M21 to turn off.
M07
Fixed loop of piercing(M07 allows to relocate the cutting torch, but impossible to return)
M08
Fixed loop of cutting stop
The operation sequence of M07 in flame cutting operation is as follows:
1
．
Open acetylene(gas) valve and ignite the torch if the valve is not open.
2
．
Lower the cutting torch(for time delay of torch lowering, see M71 command);
3
．
Open the oxygen preheating valve and count preheating time delay. If the preheating time is insufficient, it
will be prolonged to 150 seconds automatically by pressing [PAUSE] key. If preheating is done in the
midway, press [START] key to abort the time delay. The new preheating time will be automatically saved
in the parameter of preheating time delay.
4
．
Lift the cutting torch(and count the time delay of lifting torch, M72);
5
．
Open the cutting oxygen valve(M12), count the time delay and lower the cutting torch(count the time delay
of lowering torch , M73).
6
．
Switch on height controller(M38) and run the subsequent program.
The operation sequence of M07 in plasma cutting operation is as follows:
1
．
Lower the cutting torch(and count the time delay of lowering torch, see M71);
2
．
If hole positioning option is enabled(refer to SETUP), the cutting torch will move down until hit the
lower limit switch. Then the cutting torch will move up until the hole positioning time delay is up.
3
．
Turn on the arc ignition switch.
4
．
Test the signal of "Arc Voltage Successful", which will not be tested if the arc voltage test option is
taken to 0(not test). When arc ignition is successful, the piercing time delay will start to count in
seconds.
5
．
Switch on height controller(M38) and run the subsequent program.
M08: fixed loop of cutting stop
The operation sequence of M08 in flame cutting operation is as follows:
1.Close the cutting oxygen valve(M13).
