Use the program interrupt or dressing interrupt features if you want to
execute a subprogram or paramacro program while suspending operation
of some other currently executing program, subprogram , or paramacro.
Two styles of interrupts are available:
ProgramInterrupts
(Type 1 and Type 2)

thatan operationdefinedin a subprogramor paramacroprogram canbe
performed. This styleof interruptis not typicallyusedto interruptprogram
execution during reciprocation asfinish resultscanbe undesirable.
DressingInterrupts
(Type 2 only)
Seepage22-10
Use this interrupt exclusively to interrupt reciprocation or grinding cycle
operationso thatan operation definedin a subprogramorparamacro
programcan be performed. This styleof interruptistypicallyused for
dressing.
Use program interrupts to temporarily halt the currently executing program
and transfer execution to a subprogram or paramacro program . During
reci procation, a program interrupt request can cause finish problems as the
grinding wheel can be decelerated across the part during the reciprocation
pass.
We recommend that you use dressing interrupts if you want to interrupt
reci procation. We describe the actual operation of program interrupts
during reciprocation in the section, “Immediate vs. Delayed Interrupts,”
on page 22-7.
