Fast positioning of the orbit channel

This command is special for the die sinking function.

The command permits the fast positioning of the orbit channel at radius zero supplied by the down channel.

The orbit channel positions in a cycle up to the end position of the next motion stop point. The orbit channel can then skip motions in a cycle without exceeding an acceleration.

If the radius is unequal to 0, the orbit channel interpolates the geometry at the applied feed rate.
