Reference Moves
Use reference moves to move the axes to a known starting location and
orientation. Reference functions include Find Reference, Check Reference,
Wait Reference, Read Reference Status, Load Reference Parameters, and
Get Reference Parameters.
Use the Check Reference function to determine if the Find Reference
operation is complete. This function is often placed in a loop that continues
until the status for the Find Reference operation is shown to be complete.
You can use the Wait Reference function if there is no need to monitor the
status of the Find Reference function.
Find Reference Move
Use a Find Reference move to initiate a search operation to find a reference
position. Available search operations include home switch, index pulse,
forward limit switch, reverse limit switch, center, or run sequence. Refer to
the NI-Motion VI Help or the NI-Motion Function Help for information
about reference move options.
