Running a Program
Chapter 7
7-20
ATTENTION: When a program is run during quick check
mode, the control performs all coordinate system offset
operations. This means that changes to the coordinate systems
or coordinate offset tables are made (G10 blocks, changes to
G92 and G52 offsets, and changes to the active work coordinate
systems G54-G59.9). All of these changes are discarded at any
termination of QuickCheck. The pre-QuickCheck values are
restored when the {Stop Check} softkey is pressed. Note that
program changes to the active offset or tool offset tables are
not made in QuickCheck mode.
When axis inhibit is activated, the control can execute a part program
without moving specified axes. The control simulates axis motion by
updating the axis location and feedrate displays, using the commanded
feedrates, acceleration, and deceleration. If graphics are being used, the
paths of any inhibited axis are still drawn on the graphics screen.
The control executes the program in approximately the same amount of
time as it would be in automatic mode, even though some or all axes may
not physically move. You can use the axis inhibit feature in conjunction
with dry run.
ATTENTION: When testing a program using axis inhibit, the
control still recognizes and executes M, B, S, and T codes. To
ignore M, B, S, and T codes, execute axis inhibit in conjunction
with miscellaneous function lock (see page 7-2).
You can activate axis inhibit to inhibit motion of any or all of the axes,
including jogging moves, depending on the configuration determined by
your system installer. This includes jog moves. When axis motion has
been inhibited for a single axis, the remaining axes still execute as normal
and the axis location display is updated as if axis motion was occurring on
all axes.
ATTENTION: Axes not selected for axis inhibit move as they
would if the program were executed in automatic mode.
