Parameters for distance control
When electronic probe systems or sensors are used, the distance control (e.g. touching a curved surface of a plate) or height control (e.g. compensation for thickness tolerances of the workpiece) permits, for example, movements in a Z axis that superimpose the programmed positions of the axes for interpolation of an NC program.
Notice
Distance control is currently only available for SERCOS, Profidrive or CANopen drives.
Settings relevant to distance control can be defined using the following axis parameters. For more information, see in [FCT-M3].
