MC_SetReferenceFlag
The MC_SetReferenceFlag function block changes the current axis is homed state of an axis. This function block is required when not the MC_Home function block but any other mechanisms are used to home the axis (e.g. move to a mechanical stop). In this case the home position can be set using the MC_SetActualPosition function block.
