For specifying as well as storing and managing (travel) profiles, the following function blocks are
available:

POS_dnSetPosRelative_p
C02678/3 | DINT
From V5.0
Current relative position setpoint of the current positioning in [increments]
• The value is also output if the basic function "Positioning" is deactivated.
• Reference point is the starting position of the current profile.
• After a positioning process has been completed, the output keeps the last relative
value of the setpoint profile.
• The output is reset when a new positioning is started, or when the home position
is set.
POS_dnActPosRelative_p
C02678/4 | DINT
From V5.0
Current relative actual position value of the current positioning in [increments]
• The value is also output if the basic function "Positioning" is deactivated.
• Reference point is the starting position of the current profile.
• The output follows the current position even if the basic function "Positioning" is
no longer active.
• The output is reset when a new positioning is started, or when the home position
is set.

Function block Function
L_PosPositionerTable ...serves to store and manage up to 100 (travel) profiles and to "Teach"
positions, speeds, accelerations/decelerations and S-ramp times.
• A further important task of this FB is the conversion of the table values
according to the preselected scaling in the LS_DriveInterface SB.
L_PosProfileTable ...serves to store and manage up to four (travel) profiles and allows the
"teaching" of target positions.
• In contrast to the FB L_PosPositionerTable this FB does not use any
variable tables but the data of the profile parameters are entered directly
into the assigned codes.
• The position at the input dnExtPos_p is used as target position as a
further specific feature for the selection of profile no. 1.
L_PosProfileInterface ...provides a profile data set for the LS_Positioner SB.
