Overview

Task

The “contour look-ahead” function of the CNC provides the PLC with programmed contour elements on the HLI in advance.

Effectiveness / possible applications

Process parameters, such as velocity, can be optimised based on the information about the future contour.

Parameterisation

The “contour look-ahead” function must be configured with the following parameters:

• P-CHAN-00650 (alternatively P-STUP-00070) and
• P-CHAN-00658 (alternatively P-STUP-00076).

Programming

In order to command the CNC to provide future contour elements on the HLI,

• program sequences can be marked using the commands #CONTOUR LOOKAHEAD LOG ON/OFF or
• the PLC can send a request via the control unit.
