Term/abbreviation Meaning
Position set Positioning command defined in the position set table, consisting of target
position, positioning mode, positioning speed and accelerations. Maximum
31 position sets are possible on the SFC−DC with I/O control.
Project zero point (PZ) Measuring reference point for all positions in positioning tasks (Project
Zero point). 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
control or diagnostic interface). Reference point for the project zero point
is the axis zero point (on the SFC−DC−...−IO the project zero point PZ and the
axis zero point AZ are identical).
Referencing
(Homing mode) Operating mode in which reference travel is carried out.
Referencing method Method for defining the reference position: against a fixed stop
(overcurrent/speed evaluation) or with reference switch.
Reference point (REF) Relative point for the relative measuring system. The reference point de
fines a known position/orientation within the positioning path of the drive.
Reference switch External sensor (e.g. type SME−10/SMT−10) which serves for ascertaining
the reference position and is connected directly to the controller.
Reference travel The reference position and therefore the source of the measuring reference
system of the axis will be defined by the reference travel.
SLTE... Type designation, electric slide.
Software end position Programmable stroke limitation (reference point = axis zero point)
Software end position, positive:
Max. limit position in positive direction (away from the motor); must not be
exceeded during positioning.
Software end position, negative:
Min. limit position in negative direction (towards the motor); must not be
exceeded during positioning.
Teach mode Operating mode for setting positions by moving to the target position e.g.
when creating position sets.
Tip mode Manual positioning in positive or negative direction (only on field bus
variants of the SFC−DC via the field bus or only with FCT or operator panel)
