7.1 Explanation of positioning functions
7.1.1 Unidirectional positioning
A unidirectional format is used for VS-212DN positioning.
To execute positioning from the opposite direction, the target stop position must be overshoot first, with
positioning then occurring from the prescribed direction after making a U-turn. The unidirectional
positioning format reduces positioning errors caused by gear backlash, etc.
(1) The VS-212DN automatically determines if a position overshoot is necessary based on whether the
current position value is larger or smaller than the target stop position value, and on the FWD
(forward) or RVS (reverse) positioning direction (designated by parameter setting).
(2) The overshoot amount is determined by a parameter setting. If the overshoot amount is
designated as ‘0’, bidirectional positioning (no overshoot) will occur.
