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
