Running a Program
Chapter 7
7-18
ATTENTION: Once axis reciprocation begins, it continues
through program block execution until stopped by a G80, an
end of program (M02, M30, M99), a change to manual mode or
an emergency stop. This means executing an M00 or an M01 in
a part program does not necessarily stop the reciprocating axis.
(3) Entering a Sequence Stop Number
To interrupt execution at a specific block in the part program, use the
sequence stop feature described on page 7-2. The control stops automatic
operation after it completes the commands in the designated block.
(4) Feedhold Status
Your system installer may have written PAL to allow the activation of a
feedhold status through the use of a button or switch. When activated, the
control decelerates all moving axes to a feedrate of zero until the feedhold
status is deactivated. For details on using feedhold, see the documentation
provided by your system installer.
QuickCheck is a basic syntax checker for a part program. It checks that
proper format and syntax have been followed during programming. No
actual programmed motion is produced in QuickCheck mode. The
QuickCheck feature is also available with an optional graphics feature.
ATTENTION: It is your system installers responsibility to
insure that no axis motion is generated from the PAL axis mover
feature in the QuickCheck mode. Also any jog moves that can
be performed on your system in automatic mode (features such
as Jog Retract, Manual Gap Elimination, or Jog on the Fly) can
produce axis motion in QuickCheck mode.
Modal features that are already active (such as G81 reciprocation, spindle
direction and speed, and modal M codes that operate coolants or other
peripherals) will remain in their current state when the QuickCheck mode
is entered. For example if you start the spindle at 1000 RPM in the
clockwise direction it continues to run at that RPM in that direction
regardless of any commands executed in QuickCheck mode.
