3 Operating Sequences

3.2.3 Influencing ”AUTOMATIC” operation

Start:

Every time the "START OPS" softkey is pressed, the next program to be pro-
cessed according to the list is loaded into the NC memory. The first program is
demanded immediately, all following ones after processing of the previous
program has ended.

START
OPS

Sequence of operation

Whether the NC has to be restarted manually after the

new program has been loaded or whether it is

restarted automatically, is set by the machine tool

manufacturer.

Display:

The 2nd line in the screen form (marked by >...<) is the "actual line", which is
being processed.
The "REM" column indicates the number of program runs remaining until the set
quantity (= "RQD" column) has been reached. It is updated after each change
of program.
After each change of program the list moves up one line in the screen form, so
that the following program appears in the "actual line" (scroll function).
After the last run of the last program the initial display is shown again, i.e.
consecutive number 1 is in the "actual line".

Interruption:

If OPS is to be interrupted (not ended!), e.g. in case of tool breakage, the
"STOP EDIT" softkey must be pressed; automatic retroloading is then inter-
rupted (it depends on the user PLC program if this triggers "NC RESET" at the
same time). The cursor appears in the "actual line" of the screen form.

Continuation:

Pressing "START OPS", you resume program sequencing directly at the
interruption point of the program sequence.
If you wish to proceed with a different part program, i.e. restart from a different
line of the program sequence list, you can change the consecutive number in
the screen form before starting.

STOP
EDIT

START
OPS

Sequence of operation

Note:
If the same part program is to be executed with a quantity other than the remaining amount,
you may change this number before the start.
If the consecutive number and the remaining quantity are both

changed at the same time,

only the new consecutive number will be taken into account!
