■Setting example (When MR-J4-B-RJ is connected) [RD77MS]
The following shows an example for setting a serial absolute synchronous encoder Q171ENC-W8 using MR-J4-B-RJ as
synchronous encoder axis 1 of the Simple Motion module.

Set the parameters as below.
• Set "103: Synchronous encoder via servo amplifier (servo amplifier axis 3)" in "[Pr.320] Synchronous encoder axis type" of
synchronous encoder axis 1.
• Set "MR-J4 series" in "[Pr.100] Connected device" of the axis to connect Q171ENC-W8.
• Set "1_ _ _H" or "2_ _ _H" in the servo parameter "Scale measurement function selection (PA22)". (Set "ABS" or "INC" from
the "External synchronous encoder input" list of the amplifier setting dialog using the Simple Motion Module Setting
Function.) [RD77MS]
• Set "1_ _ _H" in the servo parameter "Function selection C-8 (PC26)".
■Setting example (When MR-J5-B-RJ is connected) [RD77MS]
The following shows an example where the MR-J5-B-RJ set as Axis 3 is used for synchronous encoder axis 1 of the Simple
Motion module and the rotary servo motor HK-KT series is used as the scale measurement encoder.

• Set "103: Synchronous encoder via servo amplifier (servo amplifier axis 3)" in "[Pr.320] Synchronous encoder axis type" of
synchronous encoder axis 1.
• Set the MR-J5 series for "[Pr.100] Servo series" of the axis that uses the scale measurement function.
• Set "1: Used in absolute position detection system" or "2: Used in incremental system" in the servo parameter "Scale
measurement function selection (PA22.3)" of the MR-J5-BRJ. (Set "ABS" or "INC" from the "External synchronous encoder
input" list of the amplifier setting dialog using the Simple Motion Module Setting Function.)
