Drilling pattern cycles

The drilling pattern cycles only describe the geometry of an arrangement of drilling holes in the plane. The link to a drilling
process is established via the modal call of this drilling cycle before the drilling pattern cycle is programmed.
12.5.1 Requirements
D rilling pattern cycles without drilling cycle call
Drilling pattern cycles can also be used for other applications without prior modal call of a drilling cycle because the drilling
pattern cycles can be parameterized without reference to the drilling cycle used.
If there was no modal call of the subroutine prior to calling the drilling pattern cycle, error message 62100 "No drilling cycle
active" appears.
To acknowledge the error message, press the following key:
To continue the program execution, press the following key:
The drilling pattern cycle will then approach each of the positions calculated from the input data one after the other without
calling a subroutine at these points.
Be havior when quantity parameter is zero
The number of holes in a drilling pattern must be parameterized. If the value of the quantity parameter is zero when the cycle
is called (or if this parameter is omitted from the parameter list), alarm 61103 "Number of holes is zero" is issued and the
cycle is aborted.
C h ecks in case o f limited ranges of input values
Generally, there are no plausibility checks for defining parameters in the drilling pattern cycles.

This cycle can be used to produce a row of holes, i.e. a number of holes arranged along a straight line, or a grid of holes.
The type of hole is determined by the drilling cycle that has already been called modally.
