Tab.B/7: Dimension reference system for pneumatic drives with absolute measuring system
The vectors a’ to e are user specifications provided these
cannot be recognised (e.g. cylinder and measuring system
length with the DGCI).
The axis zero point always has to be on the cylinder zero
point! This is necessary because the controller requires the
absolute
piston position within the cylinder.
