1.5.2 Signs and directions
All offsets and position values are vectors (with a given al-
gebraic sign, + or -). The active direction can be reversed on
the control panel (see 5.2.1) or via FCT. This can be useful
when using angular gear units or toothed belt drives. A hom-
ing run must be carried out again if the direction is reversed.
The direction in which the work load moves depends on the
gearing, the spindle type (left/right-rotating), the algebraic
signs on the positioning specifications, and the set active
direction.
