REMARK
(1) 1: The logic of 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 QD75D
upper limit (FLS) and lower limit (RLS) are used in the OPR retry function. Set these signals
inside the servo amplifier limit switches.
(3)
3: Refer to the manual of the servo amplifier for information on the servo amplifier side wiring and various signal
wire shields not shown above.
(4)
4: Use the same logic (positive logic/negative logic) for the QD75D
and servo amplifier. The QD75D
is
initially set to negative logic.
(5)
5: This indicates the distance between the QD75D and
