Overview

Task

Distance control has the task of controlling the distance between tools and workpieces. This takes place by additional electronic probe systems or sensors which detect the actual distance and then send the measurement to the controller.

For example, distance control compensates for thickness tolerances in workpieces or prevents the tool from contacting the workpiece in the event of surface unevenness.

Characteristics

There are two types of distance control:

axis-specific variant, also height control, that is configured for an axis
channel-specific variant, also 3D distance control

Parameterisation

The parameters for each variant are configured either:

in the parameters of each axis list for axis-specific variants
or in the parameters in the channel for 3D distance control

Programming

Each of the variants is programmed either:

by the NC command <axis_name> [ DIST_CTRL ...] or by the PLC for axis-specific variants
By the NC command #DIST CRL[…] for channel-specific variants

Mandatory note on references to other documents

For the sake of clarity, links to other documents and parameters are abbreviated, e.g. [PROG] for the Programming Manual or P-AXIS-00001 for an axis parameter.

For technical reasons, these links only function in the Online Help (HTML5, CHM) but not in pdf files since pdfs do not support cross-linking.
