Near-point dog

External command

24V, 0.2A or higher

(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".)

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

2: The QD75D N 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 amplifier (for stop).

4: This indicates the distance between the QD75D N and servo amplifier.

5: Use the same logic (positive logic/negative logic) for the QD75D N and servo amplifier. The QD75D N is

initially set to negative logic.

Configure a sequence to turn OFF the MC

at alarms and emergency stops.
