You can activate the Axis Inhibit feature using a switch installed by your
system installer (see documentation provided by the system installer) or by
using the
{FRONT PANEL}
softkey (see page 2-13). The control must be in
cycle stop or E-Stop to activate or deactivate the Axis Inhibit feature. Any
attempt to activate or deactivate the feature during program execution or
when in cycle suspend or feedhold states is ignored. Attempts to activate
the Axis Inhibit feature during jogging are also ignored.
Press to program execution with the Axis Inhibit feature.
Make sure you select a program for execution. See page 7-6.
You can stop program execution with Axis Inhibit at any time by using any
of the methods described for normal program execution or by pressing the
button.
WARNING: Axes not selected for axis inhibit move as they
would if the program were executed in automatic mode.
The spindle motion may also be inhibited by using a switch installed by
your system installer. See the documentation provided by your system
installer. The spindle cannot use the
{FRONT PANEL}
softkey to activate
the Axis Inhibit feature.
The Dry Run function permits the checking of a part program to make
sure that machine motions are correct. It is intended to be executed
without the material or part mounted. The dry run function replaces all
programmed feedrates with the maximum cutting feedrate. Jogging moves
and moves that are programmed using rapid traverse (G00) are not affected
by dry run.
The Axis Inhibit feature can be used in conjunction with Dry Run if
desired.
If you use the external decel feature simultaneously with the Dry Run
feature, the feedrates that are assigned to External decel feature are used
and the Dry run request is ignored.
