10.4.14 Positioning movements

Function
Axes can be positioned completely asynchronizedly with
respect to the part program from synchronized actions.
The programming of positioning axes from
synchronized actions is advisable for cyclic sequences
or operations that are strongly dependent on events.
Axes programmed from synchronized actions are called
command axes.
In SW 5 and higher, G codes G70/G71/G700/G710 can
be programmed in synchronized actions. They can be
used for defining the measuring system for positioning
tasks in synchronized actions.
References:
The measuring system is defined using
G70/G71/G700/G710.
By programming the G functions in the synchronized
action, the INCH/METRIC evaluation for the
synchronized action can be defined independently of
the part program context.
