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
The LD75D upper limit (FLS) and lower limit (RLS) are used in the OPR retry function. Set these signals inside the
servo amplifier limit switches.
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
Use the same logic (positive logic/negative logic) for the LD75D and servo amplifier. The LD75D is initially set to
negative logic.
*5
This indicates the distance between the LD75D and MINAS-A4 series.
