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 "
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.)
(3)
2: The QD75D
upper limit (FLS) and lower limit (RLS) are used in the OPR retry function. Set these signals
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
and servo amplifier.
(6)
5: Use the same logic (positive logic/negative logic) for the QD75D
and servo amplifier. The QD75D
is
initially set to negative logic.
