1494 HEIDENHAIN Technical Manual iTNC 530 HSCI
Line 0:
The pallet with the name 120 is defined. The NC macro for changing the pallet
is activated. The active datum equals the machine datum. A clearance height
was programmed.
Line 1:
A fixture is defined and a clearance height is specified. The NC macro for
changing the fixture is active.
Line 2:
The fixture holds an unmachined part to be machined with NC program
PART1.H (workpiece-oriented machining).
Line 3:
The fixture holds a second unmachined part to be machined with NC program
PART2.H (tool-oriented machining).
The active datum is offset from the pallet datum by the given values.
Line 4:
The pallet with the name 130 is defined. The NC macro for changing the pallet
is activated. The active datum is offset from the machine datum by the given
values. The datum table NULL1.D is active.
Lines 5 and 6:
The pallet holds two unmachined parts which are to be machined together in
one setup with NC programs PART3.H and PART3B.H (tool-oriented machining).
The active datum of the first part is offset from the pallet datum by the given
values.
PLC Marker M4196 informs the PLC program if pallet machining was stopped
because there are no more valid jobs according to the identifiers in the pallet
table ("W status" column set on ENDED). For infinite machining (bits 2 and 3
of MP7683 set) the marker means that no more jobs are available. It is
possible that the marker is only set several cycles after the deletion of M4176.
The marker is not reset by the NC but must be reset by the PLC program when
appropriate. Depending on the contents of the bits 0, 1, 2, 3 and 8 in MP7683,
there may still be jobs that have not yet been processed, even if the marker is
set.
