2. LINEAR SCALES
(2) Connection example of 5m to 30m wiring length (This connection example assumes that the following
operating combination is satisfied.)
[Operating combination]
Used Wire Size
AWG22
[Connection example]
The wiring length is up to 30m. Depending on the wiring length, however, the number of LG and P5
connections must be changed according to the following table.

Note 1. Do not connect the linear encoder (linear scale) that is not indicated in this specification.
2. Connect the shield wire to the plate (ground plate) in the connector securely.
3. For the wiring to the servo motor, refer to the standard connection examples in Chapter 3 and the Instruction Manual of the MR-
J2S- B standard model.
4. A limit switch signal cannot be imported directly to the servo amplifier. When using a limit switch, use a photocoupler for
isolation as shown above. Contact the scale manufacturer for detailed specifications of the limit switch.
5. The encoder (scale) home position (reference mark) data is sent to the servo amplifier by serial communication.
6. Contact the scale manufacturer for detailed specifications such as the combinations, models, types, etc. of the linear encoder
(linear scale) side output cable and connector.
