Load-Side Encoder - Mitsubishi Electric MR-J4W2 Instruction Manual

16. FULLY CLOSED LOOP SYSTEM

16.2 Load-side encoder

16.2.1 Linear encoder
Refer to "Linear Encoder Instruction Manual" for usable linear encoders.
16.2.2 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. Do not use MR-EKCBL30M-L, MR-EKCBL30M-H, MR-EKCBL40M-H, or
MR-EKCBL50M-H as they are four-wire type.
16.2.3 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.

Note. Use a two-wire type encoder cable. A four-wire type linear encoder cable cannot be used.
POINT
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.
