Op- Name Description
tion
[0]* Target posi- The drive uses the latest target position as reference for the new positioning command. The drive exe-
tion cutes the new positioning command immediately without completing the previous positioning. The
new target is calculated with the formula: New target = previous target + position reference.
[1] Buffered tar- The drive uses the latest target position as reference for the new positioning command. The drive exe-
get pos. cutes the new positioning command when it completes the previous command. Only 1 positioning
command can be buffered at a time.
[2] Comman- The drive uses the commanded position as reference for the new positioning command. The drive exe-
ded position cutes the new positioning command immediately without completing the previous positioning. The
new target is calculated with the formula: New target = commanded position + position reference.
[3] Actual posi- The drive uses the actual position as reference for the new positioning command. The drive executes the
tion new positioning command immediately without completing the previous positioning. The new target is
calculated with the formula: New target = actual position + position reference.

This option selects the relative position mode permanently. All positioning commands are consid-
ered to be relative. Toggling option [113] Enable Reference on a digital input or the enable reference
fieldbus bit triggers relative positioning.
This option selects the enable-reference mode permanently. Any new position reference triggers an
