Alternating orbiting
Process control by PLC
Down channel | Orbit channel | Escape channel | Escape condition |
Vext =0, when dist_prog_startEsc > Sliding distance or vGen < 0 Vext = VGen, when VGen> 0 and dist_prog_startEsc < Sliding distance | Vext | Vext | Vext< 0 and |
In alternating orbiting, the down channel and the orbit channel always move in alternating sequence. Channel synchronisation always takes place between the down and orbit channels. The down channel moves to the next position at which a disc is eroded. After it reaches the position, it synchronises with the orbit channel and the orbit channel erodes a complete disc. When the entire disc has been eroded, the orbit channel synchronises with the down channel and the process starts again from the beginning.
