L_SSC_SetPosition - position conversion
Outputs
20.16 L_SSC_SetPosition - position conversion
This FB converts a position to a position in [increments] on the basis of the machine
parameters transmitted and provides them at the output dnPosOut_p for further
processing within the function block interconnection.

Identifier/data type Information/possible settings
scAxisData
SSC_Axis_logic
Machine parameters
• Pointer to a data structure the elements of which contain the machine
parameters in the internal measuring system.
• Via this "interface" you can provide the machine parameters to other FBs, which
require these data for internal calculations.
diCycleLength_p
DINT
Cycle in [increments]
• The cycle in the real unit of the machine can be viewed in the corresponding code.
