5.120 L_SdGetAxisData - Reading out machine parameters from axis data
This FB reads out selected machine parameters from the copied axis data and makes them available
to other FB which require them for internal calculations (e.g. master value integrators, FB for stret-
ching/compression, and other FB for the edition of cam data).

Identifier/data type Information/possible settings
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)
Identifier/data type Value/meaning
dnCycleLength_p
DINT
Cycle in [increments]
• C04416 indicates the cycle in the real unit of the machine.
dwCycleLengthRes
