9.4.26 Automatic and automatic single-block mode [826, 828]
You will find detailed information on "Automatic mode" and
"Automatic single-block mode" in the chapters of the same name
in the Function Description of manual /1/.
The "Programming guide" chapter of manual /1/ describes how to
write automatic NC programs for the automatic modes in a
programming language conforming to DIN 66025.
Sheet [828] shows how to enter and edit automatic blocks step-by-step
via MASTERDRIVES parameters U571 to U591 (see the parameter list
for exact procedure).
9.4.27 Roll feed [830]
MD1 = 3 and MD11 > 0 activates the "roll feed" axis type, and the
special block execution shown in [830] is valid for MDI, automatic and
automatic single-block modes. The traversing curve can be adapted
highly flexibly to the system conditions. In automatic mode you can start
a new block on-the-fly with the "external block change" function, e.g.
after detection of a printing index in order to cut printed material to
length in an application where a printed image is to appear exactly in
the middle of a packaging bag.
The loop counter enables the process of consecutive cutting to length
of a selectable number of material pieces to be automated. The loop
number can be set via the task interface of the S7 standard software
GMC-BASIC /1/ or parameter U507. The loop count that has not yet
been processed can be read at parameter n540.36.
