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.
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.
