3.2 Function Menu Item Description:
3.2.1 SPEED
In automatic mode, at the top left corner of the screen, it shows F× (multiplying factor of automatic machining speed)= set machining speed.
In manual mode, at the top left corner of the screen, it shows F× (multiplying factor of manual speed)=manual speed.
SPEED indicates the actual speed while the active speed multiplying factor is adjustable with [F
↑]
and [F
↓].
It is allowed to adjust the speed quickly by pressing [F] key in this window. A pull
-
down menu will appear with 8 speed multiplying factors
available for selection with
[↑]
and/or
[↓]
key: 5%, 20%, 30%, 40%, 50%, 60%, 80% and 100%. And then, press ENTER key to
acknowledge the selection.
Attention:
The speed may be indicated in
Metric
or
English
system depending on the Metric/English Selection in
SETUP
(Refer to
Parame-
ter Control
).
3.1.2 PROG, PIERCE and KERF
They are used to indicate the name of machining program, serial number of pierced hole(automatic clear in automatic machining mode) and the
active compensating width of kerf respectively.
3.2.3 WORKMODE, OPERATE
WORKMODE field indicates the active operating mode such as rotation selection, breakpoint recovery, mirroring and section selection.
OPERATE field indicates such information as machining/pause, limit alarms and time delay.
3.2.4 Input and output
Below the heavy
-
current switches, there are 3 rows×8 indicators
○.
The top indicators show the status of 13 input ports,
○
indicating no signal input and
●
indicating signal input.
The bottom indicators show the status of 8 output ports,
○
indicating no signal output and
●
indicating signal output.
See the description of
DIAGNOSE
function for the definitions of input/output ports.
3.2.5 Machining Parameters Indication
This zone indicates various parameter values in the current machining mode.
3.2.6 Selection of coordinate unit
The coordinates may be indicated in
Metric
(millimetre) or
English
system(inch) depending on the Metric/English Selec-
tion in SETUP(Refer to Parameter Control).
3.2.7 The six heavy
-
current control keys on the front panel are designed to exert heavy
-
current control of external
source.
[IGN]: Refer to
Ｍ
20 for ignition feature.
[PREHEA]: To open the solenoid valve of preheating oxygen. Refer to
Ｍ
24 for details.
[GAS]: To open the solenoid valve of acetylene
（
gas). Refer to
Ｍ
10 for details.
[CUT]: To open the solenoid valve of cutting oxygen; refer to
Ｍ
12 for details. To turn on the arcing switch if it is
plasma
.
[PIERCE] heavy
-
current control key
To carry out a piercing process, the specific operation procedure is as follows:
Flame machining case:
rise the cutting torch(M72), open the cutting oxygen(M12) and lower the cutting torch
(M73).
