Programming Cycles Externally - Siemens Sinumerik 840D sl Programming Manual

Programming cycles externally

16.1 Technology cycles
Compatibility
The technology cycles from version 2.6 onwards are a further development of the cycle
packages for SINUMERIK 840D sl up to GIV 1.5 (cycles up to version 7.5). NC programs with
cycle calls for these earlier software versions will still run.
Most cycles have been extended by new transfer parameters or the range of existing
parameters has been extended in order that new functions can be programmed (e.g.
Parameter _VARI for the type of machining, which is used often).
The term "Compatibility" in this documentation indicates input values that have not been
programmed before. If values are supplied accordingly, the cycle runs with the same
functions as up to version 7.5.
Repeating cycles on a position pattern
Drilling and milling cycles can be repeated on the position pattern (modal calls). In such cases
MCALL should be written in the same line before the cycle, e.g. MCALL CYCLE83(...).
Note
If certain transfer parameters (e.g. _VARI, _GMODE, _DMODE, _AMODE) have been indirectly
programmed as parameters, the input mask is opened on recompiling but it cannot be stored
as there is no unique assignment to defined selection fields.
