AZ
PZ Homing point (or reference point): point determined during the homing run: reference
switch or stop.
Axis zero point: point of reference for the project zero point and the software end positions.
Project zero point: Reference point (= zero point) for actual position and absolute positions
in the position set table.

b, c
d Axis zero point offset: distance between axis zero point AZ and homing point REF
Software end position offsets: limits for the permitted positioning range (= effective stroke)
Project zero point offset: distance from AZ
e
f Effective stroke: permitted positioning range
