Conditions
The following conditions must be satisfied to approach fixed points with
● The fixed-point coordinates must have been calculated exactly and written to machine
● The fixed points must be located within the valid traversing range (→ note the software
● The axes to be traversed must be referenced.
● No tool radius compensation must be active.
● A kinematic transformation may not be active.
● None of the axes to be traversed must be involved in active transformation.
● None of the axes to be traversed must be a following axis in an active coupling.
● None of the axes to be traversed must be an axis in a gantry grouping.
● Compile cycles must not activate motion components.
