Remaining Workpieces -- indicates the number of workpieces that still
need to be cut in the lot. The value for this field is automatically set equal
to the lot size each time the “Lot Size” value is changed. When the control
encounters an M02, M30, or M99 in a main part program, the remaining
workpieces field is decremented by one. The control tells the system
installers PAL program when the lot remaining size is zero. At this point,
press
<CYCLE START>
to automatically set the field back to the “Lot Size”
value. Complete operation of this feature is somewhat PAL dependant.
Refer to the documentation supplied by your system installer.
Lot Completion Flag -- is automatically set to zero by the control
whenever a non-zero value is entered for “Lot Size.” It is set to one when
the “Remaining Workpieces” field reaches zero. It is again reset to zero
when the next cycle start occurs after the remaining workpieces field has
reached zero. Complete operation of this feature is somewhat PAL
dependant. See the documentation supplied by your system installer.
Press the exit softkey {

Program” screen.
