Sinumerik Alarm 12700 Channel %1 block %2 contour definition programming not allowed as modal sub program is active
%1 = Channel number
%2 = Block number, label
In the external language mode, a block is programmed with contour definition and a modal cycle is active at the same time. Because of unclear address assignment (e.g. R = radius for contour definition or return plane for drilling cycle) contour definition programming must not be used when a modal cycle is active.
