You can activate the axis inhibit feature by using a switch installed by your
system installer (see documentation provided by your system installer) or by
using the
{FRONT PANEL} softkey (see page 2-11). The control must be in
cycle stop or E-Stop to activate or deactivate the axis inhibit feature. The
control ignores any attempt to activate or deactivate the feature during
program execution or when in cycle suspend or feedhold states. The control
also ignores attempts to activate the axis inhibit feature during jogging.
You can also inhibit spindle motion by using a switch installed by the
system installer. See the documentation provided by the system installer.
The spindle cannot use the
{FRONT PANEL} softkey to activate the Axis
Inhibit feature.
Press the <CYCLE START> button to start program execution with the axis
inhibit feature provided a program has been selected for execution (see
page 7-6 for selecting a program).
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
<EMERGENCY STOP> button.
The dry run function permits the checking of a part program to make sure
that grinder 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 grinding feedrate. Jogging moves and moves
that are programmed using rapid traverse (G00) are not effected by dry run.
You can use the axis inhibit feature in conjunction with a dry run.
If you use the external decel feature simultaneously with the dry run
feature, the control uses the feedrates that are assigned to external decel
feature and ignores the dry run request.
You can use the <FEEDRATE OVERRIDE> switch to modify the grinding
feedrate. Your system installer determines in AMP if rapid feedrates are
overrides by the
<RAPID FEEDRATE OVERRIDE> switch or the
<FEEDRATE OVERRIDE> switch during dry run.
ATTENTION: When testing a program using dry run, the
control still recognizes and executes M, B, S, and T codes. To
ignore M, B, S, and T codes, execute dry run in conjunction
with miscellaneous function lock (see page 7-2).
