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.
