CNC System Instruction
Two starting methods in automatic mode:
a) Press the green [START] key on the front panel.
b) Press an external "START" key(See the definition of input/output ports).
3.5. Control and adjustment of cutting position in automatic mode
3.5.1 Only the following keys are enabled when the system starts automatic mode:
[PAUSE]: If this key is pressed, the system will slow down and stop movement, shut off cutting oxygen (shut off arcing
switch in plasma machining case), turn off the height controller(M39) and remain the current display still. After the
system operation is paused, it is allowed to perform the following operations:
Return along the original path; (b)adjust position; (c)exit machining operation; (d) [START]: restore system opera-
tion; and
(e)Press [ESC] key to exit the machining program and return to automatic mode window.
[F

key: To control the vertical movement of cutting torch. By pushing and holding either key, the cutting
torch will move up or down accordingly, and the movement will stop if the key is released.
[Emergency Stop] key: It is an external key with signal received from the input port(refer to "External Input Ports" for
details). If emergency stop is validated, all the movement will stop and no output will go on. It is used for emergency
case.
3.5.2. Adjustment of cutting position
3.5.2.1Situations necessary to adjust the position of cutting torch:
If the cutting torch is blocked or replacement is necessary, the usual practice is to move the cutting torch to somewhere
safe and move it back to the starting point after the situation is resolved.
When it is required to pierce along the exterior margin and not position the piercing point at the exterior edge, the usual
practice is to pinpoint an appropriate position in the exterior of workpiece for piercing and then cut the workpiece back
to the starting point along a straight line before continue normal machining without stop.
In case of transitional cutting, too many workpiece or large size of workpiece, it might be necessary to relocate the cutting
torch.
3.5.2.2Situations allowed to adjust the cutting position:
(1) pause process, (2) return process,(3) piercing process, (4) section selection, (5) hole selection and (6) breakpoint res-
toration
If operator intends to change the position of cutting torch in the above
-
mentioned states, it is allowed to press

[↓], [←]
and/or
[→]
key to do so(in this case, it is manual multiplying factor, adjustable). When the expected posi-
tion is reached, press [Start] key, as shown in the following dialog box:
