Up to three hand wheels can be connected to the PA CNC controls. Each hand wheel can be assigned to a certain axis. The assignment is specified in the machine parameters. A hand wheel can also be used as a “free”.

The function "Infinite rotary axis" enables the endless moving of axes in one direction. By this the positions of axes are reduced automatically, without any influence for the moving of axes. In particular, this reduction has no effects on the moving of other axes (linear axes). Altogether, there are three different variants of the infinite rotary axis:

• "Normal round axis" with which maximum +- 360° is programmed.
• "Shortest way axis” which drives always on the shortest way to the programmed position (e.g. tool magazine axis).
• "Modulo rotary axis" for which rounds and an angle can be programmed.
