D ynamics limit
If a coupled axis group is activated in the part program, the dynamic response of all coupled-motion axes is taken into
account during traversing of the leading axis to avoid overloading the coupled-motion axes.
C o upling status
The coupling status of an axis can be checked in the part program with the system variable: $AA_COUP_ACT[<axis>].

D i splay of distance-to-go of the coupled-motion axis for modulo rotary axes
If the leading and coupled-motion axes are modulo rotary axes, the traversing movements in the leading axis add up from n
* 360° (n = 1, 2, 3 ...) in the distance-to-go display of the coupled-motion axis until the coupling is switched off.

Overview of cycles

Cycles are generally applicable technology subroutines that can be used to carry out a specific machining process, such as
drilling of a thread (tapping) or milling of a pocket. These cycles are adapted to individual tasks by parameter assignment.
D rilling cycle, drilling pattern cycles and milling cycles
You can carry out the following standard cycles by using the control system:
● D rilling cycles
CYCLE81: Drilling, centering
CYCLE82: Drilling, counterboring
CYCLE83: Deep-hole drilling
CYCLE84: Rigid tapping
CYCLE840: Tapping with compensating chuck
CYCLE85: Reaming 1
CYCLE86: Boring
● D rilling pattern cycles
HOLES1: Row of holes
HOLES2: Circle of holes
CYCLE802: Arbitrary positions
● Mi lling cycles
CYCLE71: Face milling
CYCLE72: Contour milling
CYCLE76: Milling the rectangular spigot
CYCLE77: Circular spigot milling
LONGHOLE: Elongated hole
SLOT1: Groove milling pattern on a circle
SLOT2: Circumferential groove milling pattern
POCKET3: Rectangular pocket milling (with any milling tool)
