REMARK
(1) It is recommended to make differential driver connection since differential driver connection is more excellent than
open collector connection in max. output pulse and max. connection distance between servos. (Refer to Section
3.1 "Performance specifications".)
(2)
1: The logic for each I/O terminal can be changed with "
signal logic selection" in detailed parameters 1. (Negative logic is used for all terminals in the example above.)
(3)
2: The QD75D
inside the servo amplifier limit switches.
(4)
3: These are limit switches for the servo amplifier (for stop).
(5)
4: This indicates the distance between the QD75D
(6)
5: Use the same logic (positive logic/negative logic) for the QD75D
initially set to negative logic.
