2. LINEAR SCALES
Connection cable connection examples (2)
The following cable wiring examples assume that the linear encoder (linear scale) is connected to CN2 of
the servo amplifier using the option cable MR-J2SCLCBL02M-P-H.
(1) Connection example of up to 5m wiring length (This connection example assumes that the following
operating combination is satisfied.)

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.
