Term/Abbreviation Meaning
Project zero point (PZ)
(project zero point) Reference point for all positions in positioning tasks. The project zero
point PZ forms the basis for all absolute position specifications (e. g. in
the position set table or with direct control via the controller or diagnos-
tic interface). The project zero point PZ is defined by a preset distance
(offset) from the axis zero point.
Reference point (REF) The reference point defines a known position/orientation within the posi-
tioning path of the drive. It is the basic reference point for the measuring
reference system.
Reference switch External sensor which serves for ascertaining the reference position and
is connected directly to the controller.
Referencing Defining the measuring reference system of the axis
Software end position Programmable stroke limitation (basis point = axis zero point)
– Software end position, positive:
max. limit position of the stroke in the positive direction; must not be
exceeded during positioning.
– Software end position, negative:
min. limit position in the negative direction; must not be exceeded
during positioning.
Teach mode
(Teach mode) Operating mode for setting positions by moving to the target position,
e. g. when creating positioning sets.
