This family of link types waits for the position of the current axis to reach a distance from the start
or end of a move. There are four separate link types in this family to cover comparing against the
start or end of the move using either the Target or Actual Position.
The TarRelCom and ActRelCom link types will link to the next step when the Target or Actual
Position (respectively) is within the Limit Position Window specified by the Link Value from the
Command Position status field, as shown below:
The TarRelStart and ActRelStart link types will link to the next step when the Target or Actual
Position is outside the Limit Position Window specified by the Link Value from the start of the
move, as shown below:
The start of the move is defined by the position when a Go (G) command is issued when the axis
is stopped, when a Sine Move (~) command is issued, or when an Open Loop (O) command is
issued.
Example:
To move to the next event step when the Target Position has moved 1000 position units from the
start of the move, the TarRelStart link type with a Link Value (Link Position Window) of 1000
would be used. Therefore, if the move is from 4000 to 12000, the link will trigger when the Target
Position reaches 5000. If the move is from 4000 to 1000, the link will trigger at 3000.
