Behavior of programmed axis types
Geometry, synchronized and positioning axes are programmed.
• Path axes traverse with feedrate F in accordance with the programmed travel commands.
• Synchronized axes traverse synchronously to path axes and take the same time to
traverse as all path axes.
• Positioning axes traverse asynchronously to all other axes. These traversing movements
take place independently of path and synchronized movements.
• Command axes traverse asynchronously to all other axes. These traversing movements
take place independently of path and synchronized movements.
• PLC axes are controlled by the PLC and can traverse asynchronously to all other axes.
The traversing movements take place independently of path and synchronized
movements.
