Linebias----
Axial bias between scriber and cuttingtorch in mm or inch.
DIR-ORIGIN----
Move back to machine zero in the direction of 0-not reset 1-positive reset 2- negative reset
Soft positive/negative limit switch----
The system will give an alarm when program coordinate exceeds the set soft
positive/negative limit. If it will not be used, the parameter should be set higher than actual values in mm or inch.
7.3. Flame Cutting Parameters
In the SETUPsubmenu, press [F3] key to enter flame parameters setting window, as shown in Fig. 7.4.
Ignition delay
——
It is the time delay when turnon the high voltage ignition switch if M20 is executedin flame cutting operation.
Preheating delay
——
It is the preheating time for piercing operation in second. 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 delay.
Lifting delay of cutting torch
——
The time delay when M70 command is executed in second. Refer to 6.4 for M auxiliary commands.
Lowering delay of cutting torch
——
The time delay when M71 command is executed, in second. Refer to 6.4 for M
auxiliary commands.
Lifting delay of piercing torch
——
The time delay when M72 command is executed, in second. Refer to 6.4 for M
auxiliary commands.
Lowering delay of piercing torch
——
The time delay when M73 command is executed, in second. Refer to 6.4 for M
auxiliary commands.
Piercing delay
——
Lowering delay of cutting torch when M07 is executed in flame piercing operation after cutting
oxygen valve is opened.
OVER CUT DELAY-TIME
——After closing cut oxygen signal, due to residual pressure within the pipe, move to the next step only
after this delay, in order to improve the cutting surface smoothness.
PRO LINE DELAY
（
SF-2100AH
）
- Each program line is executed and move to next line after this delay time.
TORCH UPAND CUT OXYGEN
（
0/1
）
（
SF-2100AH
）
- SELECT0-First lift the torch then open cut oxygen, select1-First open cut
oxygen then lift the torch.
SELECT HI HOTUP M24
（
0/1
）
- when piercing thick plates, it is necessary to use preheat auxiliary. Select this function, will open
M24 when preheating, close after preheating operation.
Note, when this option is not selected, M24 (preheat) does not close the entire process.
END PROCESS DON’T OFFOUTS (0/1)
（
SF-2012AH
）
—— When the two cutting process interval is very short, you can choose
this option, don’t close output (gas and preheat oxygen) after processing.
