The cycle-related offsetting in the master measuring system (Modulo measuring system) is
executed as in the FB L_LdAddOffsetCyclic
.
Function block Function
L_SdSetPosition1 Selection of an x offset value
•The FB L_SdSetPosition
converts the position value defined in the application
unit [unit] into an incremental value.
• The reference measuring system is the master measuring system which is defi-
ned via the FB L_SdSetAxisData
(not displayed).
L_LdPosCtrlLin1 Continuous adjustment of the x offset position
• As described, the FB L_LdPosCtrlLin serves to constantly adjust the x offset posi-
tion at the dnPosOut_p output.
• The master measuring system serves as reference measuring system.
•Important: The dnPosOut_p output position must be returned to the dnActPos_p
input.
L_LdLinearCoupling1 Synchronous function
•The FB L_LdLinearCoupling
establishes the coupling between master and axis
measuring system.
• Moreover, this FB provides the option to consider an x offset in the master value.
