Positioning movements

Function
Axes can be positioned completely unsynchonized with respect to the parts program from
synchronized actions. Programming 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.

Parameters
The measuring system for positioning tasks in synchronized actions is specified with the G
codes 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 parts program context.

;For the X tool direction, a tool length
;offset of 10 is interpolated
;Positional offset of the X tool direction
;is deleted: ...$AA_TOFF[X] = 0
;No axis is traversed;
;to the current position in WCS, the
;positional offset is added in accordance
;with the current orientation
