Circle center CC, radius and direction of rotation in the FC/FCT
block
The control calculates a circle center for free-programmed arcs
from the data you enter. This makes it possible to program full
circles in an FK program block.
If you wish to define the circle center in polar coordinates you must
use FPOL, not
CC
, to define the pole. FPOL is entered in Cartesian
coordinates and remains in effect until the control encounters a
block in which another
FPOL
is defined.
A programmed or automatically calculated circle center
or pole is effective only in connected conventional or FK
sections. If an FK section splits up two conventionally
programmed sections, the information about a circle
center or pole will be lost. The two conventionally
programmed sections must each have their own
(if necessary, identical) CC blocks. Conversely, this
information will also be lost if there is a conventional
section between two FK sections.
