17.2.3 Configuration diagram of encoder cable
Configuration diagram for servo amplifier and load-side encoder is shown below. Cables used vary,
depending on the load-side encoder.
(1) Linear encoder
Refer to Linear Encoder Instruction Manual for encoder cables for linear encoder.
(a) MR-J4-_A_ servo amplifier

(b) MR-J4-_A_-RJ servo amplifier
You can connect the linear encoder without using a branch cable shown in (a) for MR-J4-_A_-RJ
servo amplifier. You can also use a four-wire type linear encoder.
