Load-side encoder
• Always use the load-side encoder cable introduced in this section. Using other products may cause a
malfunction.
• For details of the load-side encoder specifications, performance and assurance, contact each encoder
manufacturer.
Linear encoder
Refer to "Linear Encoder Instruction Manual" for usable linear encoders.
Rotary encoder
When a rotary encoder is used for the load-side encoder, use HG-KR or HG-MR servo motor as an encoder.
Use a two-wire type encoder cable for MR-J4-_GF_ servo amplifiers. Do not use MR-EKCBL30M-L, MR-EKCBL30M-H, MR-
EKCBL40M-H, or MR-EKCBL50M-H as they are four-wire type.
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.
Linear encoder
Refer to "Linear Encoder Instruction Manual" for encoder cables for linear encoder.

MR-J4-_GF_-RJ servo amplifier
You can connect the linear encoder without using a branch cable shown in the following section for MR-J4-_GF_-RJ servo
amplifier. You can also use a four-wire type linear encoder.
