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.
12.4. Plasma Parameters Setting
In the SETUP submenu, press [F4] key to enter plasma parameters setting window, as shown in Fig. 12.5.
Positioning delay of cutting torch-----
When positioning the plasma torch, lower the torch until it hits the lower
limit siwtch. Turn on the torch lifting switch. After count the positioning delay of cutting torch, the lifting torch will
stop(M75), in second.
M commands for arc ignition-----
To set the output port of arc ignition, M12 by default
M commands for arc breaking-----
To set the output port of arc breaking, M13 by default
Notes:
When the M command for arc breaking is next higher than the M command for arc ignition, it implies they share
an output port, even number for opening and even number for closing. In this case, the system uses level control
to direct arc ignition switch. When the M command for arc breaking and the M command for arc ignition are
both even number but unequal to each other, it implies there are two output ports separately control the
opening and closing operations. In this case, the system uses pulse control with pulse width of 0.5 second.
Arc voltage test option-----
It is used to determine if arc voltage is tested or not in plasma cutting operation. To
enable arc voltage test, take 1 for the option. User should test arc voltage feedback at arc ignition and monitor
the feedback in operation. When arc voltage feedback is off, the system will pause the operation and prompt. As
a general rule, arc voltage test is enabled for thick plate machining. To disable arc voltage test, take 0 for the
option. After the arc ignition switch is turned on, the machining will start when the piercing delay is up. The
system will not test arc voltage feedback in the cutting process. Generally, arc voltage test is disabled for thin
sheet machining.
Positioning test option-----
In execution of M07 command, it is used to determine torch positioning operation or
not. If the option is taken 1, torch positioning operation will be enabled.
Piercing delay-----
If arc ignition is successful, the system will start normal cutting operation after the piercing
delay.
Height control disabling distance at corner
----- At the transition or corner of two program segments, speed and
arc voltage might change, causing unexpected nozzle knock; therefore, the system will automatically disable the
height control in such a distance from the endpoint of program segment, in mm.
