Setting example
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 QD77MS.
QD77MS
Set the parameters as below.
• Set "101: 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] Servo series" of the axis to connect Q171ENC-W8.
• Set "1 _ _ _ h" or "2 _ _ _ h" in the servo parameter "Scale measurement mode selection
(PA22)". (Set "ABS" or "INC" from the "External synchronous encoder input" list of the
amplifier setting dialog using the Simple Motion Module Setting Tool.)
• Set "1 _ _ _ h" in the servo parameter "Function selection C-8 (PC26)".
