When instructing positioning using absolute values, you must perform a zero return first of all to confirm the
origin.
(Note) When the present position preset is used, the origin after the preset differs from the initially
determined origin.
(⇒ See item "Present value preset.")
Relay area for operation relating to zero return (assignment of special I/O data area)
Parameter 1 relating to zero return (regular parameters: must be set independently on each axis)
(Note) When the origin input signal is open collector, be sure to limit the low-speed zero return to 1 kpps.
