Coupled motion

14.1.1

Brief description

14.1.1.1

Function

The "coupled motion" function enables the definition of simple axis links between a master axis
and a slave axis, taking into consideration a coupling factor.
Coupled motion has the following features:
● Any axis of the NC can be defined as a master axis.
● Any axis of the NC can be defined as a coupled axis with a specific coupling factor.
● The master axis and coupled motion axis or axes together form a coupled axis grouping.
● Any number of coupled motion axes can be assigned to a master axis.
● A total of 2 leading axes may be assigned to each coupled motion axis.
● A coupled motion axis can be the master axis of a further coupled axis grouping.
● Traversing movements of the master axis are executed in synchronism on all slave axes
based on the coupling factor.
● Coupled motion axes can be moved independently of the master axis while the coupling is
active (overlaid movements).
● The master and coupled motion axes of a coupled axis grouping are defined, and the
coupling switch on/switch off, by programming instructions in the part program or by
synchronized action.
● Coupled motion is also possible in the following manual modes: JOG, JOG REF, JOG INC,
etc.
