3.1. Description of Automatic Mode Window
3.1.1 SPEED
1)
In automatic mode, at the top left corner of the screen, it shows F×(multiplying factor of automatic machining speed)= set
machining speed.
2)
In manual mode, at the top left corner of the screen, it shows F×(multiplying factor of manual speed)=manual speed.
3)
SPEED indicates the actual speed while the active speed multiplying factor is adjustable with [F↑] and [F↓].
4)
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.
5)
Attention:
The speed may be indicated in
Metric
or
English
system depending on the Metric/English Selection in
SETUP
(Refer to
Parameter 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.
3.1.3 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.
3.1.4 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.
3.1.5 Machining Parameters Indication
This zone indicates various parameter values in the current machining mode.
3.1.6 Selection of coordinate unit
The coordinates may be indicated in
Metric
(millimeter) or
English
system(inch) depending on the
Metric/English Selection in SETUP(Refer to Parameter Control).
3.1.7
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).
