REMARK
(1) 1:The logic for each I/O terminal can be changed with " Pr.22 Input signal logic selection" and " Pr.23 Output
signal logic selection" in detailed parameters 1. (Negative logic is used for all terminals in the example above.)

(2) 2:The QD75P upper limit (FLS) and lower limit (RLS) are used in the OPR retry function.

(3) 3:Refer to the manual of the stepping motor drive for information on the stepping motor drive side wiring and

various signal wire shields not shown above.

(4) 4:Use the same logic (positive logic/negative logic) for the QD75P and stepping motor. The QD75P is

initially set to negative logic.

(5) 5:This indicates the distance between the QD75P and VEXTA UPD.
