THE SCREEN PAGES PAGE 29
Xn
If the field immediately following the axis'
denomination is not programmed, the value of
X -MEM-
is an absolute value to be reached. If
the field is programmed at 1, the
X
displacement will be relative in relation to the
last positioning value. This displacement will
be made the number of times programmed
under
CY_
. It is forbidden to program a
relative value for the X displacement in the No
1 sequence. (the DNC signals an error). If the
field is programmed at 2, the axis will be
placed at 0,0 at the beginning of positioning
and it will then execute an absolute positioning
of the programmed value.
SPE
Speed factor (0->99%, undef. = 100%)
COR
This field indicates the sum of the corrections
(constant and variable) of the displayed
sequence.
JS__ J
for Jump and
S
for Sequence.
This field allows to jump, after the next
advanced sequence, to the sequence
programmed in the
JS
field.
TIMES/POS
The first field defines the number of times the
sequence jump (programmed in
JS
) is to be
effectuated.
The
POS
field defines the number of times the
jump has already been effectuated.
NB: Programming the
JS
field without
defining the number of times will execute
an unconditional jump of the planned
sequence. Generally a sequence anterior
to the current sequence is programmed in
the
JS
field.
Similiarly to the
CY
which enables cycle
repetition,
JS
allows the repetition of a
group of sequences. This type of
programming can be very useful to carry
out a production with a minimum of stock.
