Term/abbreviation Meaning
Position set record Positioning command defined in the position set table, consisting of:
– The number of the position set record
– The absolute or relative basis of the target position
– Target position
– Positioning speed
Project zero point (PZ) Point of reference for all positions in positioning tasks. The project zero
point forms the basis for all absolute position specifications (e.g. in the
position set table or with direct control via the controller interface or
diagnostic interface). The point of reference for the project zero point is
the axis zero point.
Reference switch External sensor used for ascertaining the homing point; is directly con-
nected to the controller.
Software end position Programmable stroke limitation (point of reference = 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 Operation mode for setting positions by moving to the target position
e.g. when creating position set records.
