7.4 CONTOUR DATA (Cycle 20, DIN/ISO:
G120, software option 19)
Please note while programming:
Machining data for the subprograms describing the subcontours
are entered in Cycle 20.
Cycle 20 is DEF active, which means that it becomes
effective as soon as it is defined in the part program.
The machining data entered in Cycle 20 are valid for
Cycles 21 to 24.
The algebraic sign for the cycle parameter DEPTH
determines the working direction. If you program
DEPTH=0, the cycle will not be executed.
If you are using the SL cycles in Q parameter
programs, the cycle parameters Q1 to Q20 cannot be
used as program parameters.
