Running a Program
Chapter 7
7-17
Program interrupts that are enabled in blocks prior to the searched block
(M96L__P__), are active and available for execution once the active
program begins execution. Interrupts can not be executed while the
mid-program search operation is taking place.
After a program is written or loaded into the control, it should be
thoroughly tested before a part is mounted and cut. The control offers
three distinct testing modes in addition to fully automatic operation.
These modes are briefly described below in the order that they would
normally be implemented.
Quick Check (see section 7.7.1) ---- This mode is a basic syntax checker
for a part program. It checks that proper format and syntax has been
followed. If Quick Check has been purchased with the graphic option,
it can be used to determine if the proper tool paths are being generated
(see chapter 8). No actual axis motion is produced during Quick Check
however offsets and coordinate system shifts are performed.
Axis Inhibit (see section 7.7.2) ---- The axis inhibit mode allows the
execution of a program to take place without moving a selected axis or
axes. Programmed feedrates are active and the program executes in
approximately the same time as normal program execution. Axis
motion is simulated for any of the non-moving axes by all of the
position displays changing at the programmed feedrate. Graphics are
available on the active program graphics screen (chapter 8).
Dry Run (see section 7.7.3) ---- Dry run simply replaces all F word
feedrates in a program with a special feedrate determined by the system
installer in AMP. Graphics are available on the active program graphics
screen (chapter 8).
Part Production/Automatic (see section 7.7.4) ---- In automatic mode all of
the axes are active and all of the programmed feedrates are in effect.
Graphics are available on the active program graphics screen (chapter 8).
All of the above modes of execution begin program execution when the
<CYCLE START> button is pressed. When the control is executing a part
program block that block is shown with an * to the left of that block.
When the control has completed the execution of a block that block is
shown with an @ symbol to the left of the block. The @ symbol is usually
only seen in single block mode or in cases where it is necessary to indicate
what block automatic execution begins after.
