4.7 Axis couplings via synchronized actions
4.7.3
On-the-fly parting
Task assignment
An extruded material which passes continuously through the operating area of a cutting tool
must be cut into parts of equal length.
X axis: Axis in which the extruded material moves, WCS
X1 axis: Machine axis of the extruded material, MCS
Y axis: Axis in which the cutting tool "tracks" the extruded material
It is assumed that the infeed and control of the cutting tool are controlled via the PLC. The
signals at the PLC interface can be evaluated to determine whether the extruded material and
cutting tool are synchronized.
Actions
Activate coupling, LEADON
Deactivate coupling, LEADOF
Set actual values, PRESETON

Comment
; Length of a part to be cut off
; Start position Y axis
; Start condition for conveyor axis
; Delete any existing coupling
; Table definition
; Value pairs
; End of table definition
; Preset offset at the beginning
; Start position Y axis
; The axis is a linear axis
; Preset offset after length R3, PRESE-
TON must only be executed with WHEN
and EVERY
; New start after parting
; For X < 10, couple Y to X via table 1
; > 30 before traversed parting dis-
tance, deactivate coupling
