Orbit channel
The orbit channel has the task of moving the electrode in the X/Y plane. It therefore transforms the currently supplied radius into its programmed orbit geometry. A distinction is made in this transformation between scaling (rcurr < rMaxScal) of the orbit geometry and an equidistant adaptation of the orbit geometry (rcurr > rMaxScal).
When the orbit channel is active, the down channel only moves on the R/Z plane. The 3D motion results from the superimposition of the orbit channel.

The X and Y coordinates superimposed by the orbit channel are dependent on the radius supplied by the down channel and the current PCS position on the geometry of the orbit channel. The channel interface shown in the figure below illustrates this.
