Note 1. For example, when position selection 1 (P.OUT0) is ON, positions 0 to 7 (P.IN0 to 7) are taken
as the position data's first and second digits. (They are taken at the falling edge of P.OUT0.)
Note 2. The position sign bit specifies the position as "plus" when OFF (0), and "minus" when ON (1).
Note 3. The position data takes the value set by PP-01 (minimum setting unit).
Note 4. When the position I/A bit is OFF (0), I (incremental value) is set; when it is ON (1), A (absolute
value) is set.
Note 5. Set the speed data with the reference speed (PP-14, PP-15) override value (%). If the speed
data is set to "0," the override value will be 100%.
Note 6. With direct input, the acceleration/deceleration time is fixed at PP-20 (acceleration time 0)
and PP-22 (deceleration time 0).
Direct Input Setting Example
In this example, positioning is moved at 250 mm/s to an absolute-value position of 1,000 mm, with the
mechanical system set for 10 mm of movement per motor rotation, a minimum feed amount of 1 µm, and
a reference speed of 500 mm/s.
