[2] Synchronous encoder via servo amplifier
QD77MS LD77MS
There are restrictions in the function and the encoder that can be used by the version of the
servo amplifier.
Setting method
Used to use a synchronous encoder connected to the servo amplifier which supports the
scale measurement mode as a synchronous encoder axis.
The following servo amplifier can be used. The servo amplifier must support the scale
measurement function.
• MR-J4-B-RJ
QD77MS
• MR-J4-GF-RJ
QD77GF
Only a rotary encoder can be connected. Refer to the following servo amplifier instruction
manuals for the version of the servo amplifier which supports the scale measurement
function and the rotary encoder which can be used.
