5.83 L_LdAddOffsetCyclic - offset addition
This FB serves to add any offset position to a position signal with Modulo cycle.
• The clock pulse is created without remainder processing.

Identifier/data type Information/possible settings
dnPosIn_p
DINT
Clocked position in [inc]
• Apply the position signal with Modulo cycle to this input.
• The position must match the measuring system and must not exceed twice the
cycle length of the modulo system so that the output is still limited to permissible
values (= cycle length of the modulo measuring system). Higher values cause a
standstill at the FB output.
dnOffset_p
DINT
Offset in [inc]
• The offset may be a position of any size. This also applies to the "Modulo" traver-
sing range.
AxisData Machine parameters
• For accepting the machine parameters of the drive/motor, connect this input
with the output DI_AxisData of the SB LS_DriveInterface.
• The machine parameters of a master drive can be displayed with the
FB L_SdSetAxisData . In this case, the FB output AxisData must be connected to
this input. ( 510)
