Connection Examples
Appendix 4.1
Connection examples with servo amplifiers
manufactured by MITSUBISHI Electric Corporation
(1) Connection example of LD75D  and MR-J3-  A (Differential driver
*5
)
*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 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.
*3 These are limit switches for the servo (for stop).
*4 This indicates the distance between the LD75D  and servo amplifier.
*5 Check the logic for the LD75D

and servo amplifier in  Page 69, Section 3.4.1.
The LD75D  is initially set to negative logic.
Configure a sequence to turn OFF the MC at alarms
and emergency stops.
