2. LINEAR SCALES
Connection cable connection examples (1)
The following cable wiring examples assume that the linear encoder (linear scale) is connected directly to
CN2 of the servo amplifier.
CAUTION

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. 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.
When the Heidenhain linear encoder (linear scale) is used, the
communication system is of 4 wire type.
Change the setting of serial encoder cable selection (parameter No. 23) as
indicated below. If a wrong value is set, a servo alarm (alarm 70) occurs.
Pr.23 2 (4 wire type setting is made valid.)
