The rotary axis cannot be programmed because it is

assigned to a geometry axis and cannot therefore be

programmed directly as a channel axis.

SW 3.x and lower

Traversing through the pole (origin of the Cartesian

coordinate system) is inhibited. A movement leading

through the pole stops at the pole and an alarm is

output. With a cutter center offset, the movement

stops at the edge of the unapproachable area.

SW 4 and higher

There are two ways to traverse the pole:

1. Traversing the linear axis only

2. Traversing in the pole with rotation of the rotary

axis in the pole and travel from the pole

The setting is carried out in MD 24911 and 24951.
