Siemens sinumerik 840D sl Function Manual page 271

If (x) is a periodic curve table and this is interpreted as oscillation, the offset and scaling can
also be interpreted as follows:
• SD43102 $SA_LEAD_OFFSET_IN_POS[Y]
• SD43104 $SA_LEAD_SCALE_IN_POS[Y]
• SD43106 $SA_LEAD_SCALE_OUT_POS[Y]
• SD43108 $SA_LEAD_OFFSET_OUT_POS[Y]
If the coupling is activated and synchronous, the new set position is approached as soon as
values are written to these setting data.
