Precautions
• While the linear encoder and the linear servo motor should be oil and dust proofed, oil and dust proofing are especially
important for the linear encoder. Contact the manufacturer of the linear encoder being used.
• Use the linear encoder cables specified in this chapter. Using products other than those specified may cause a malfunction.
• Contact the manufacturer of the linear encoder being used for information on specifications, performance and guarantees.
• If the linear encoder is incorrectly installed, an alarm or position mismatch may occur. In such situations, refer to the
following check points and ensure that the linear encoder is installed in a suitable environment.
Check that the gap between the head and scale is correct.
Check that the scale head is not rolling or yawing (i.e., that the scale head is not loose).
Check the surface of the scale for dust and scratches.
Check that the vibration and temperature are within the specified range.
Check that the speed is within the permissible range without overshooting.
• Refer to the following page for combinations of linear encoders and servo amplifiers.

connectors
• When using 3M shell kits (36310-3200-008 or 36310-F200-008) or the Molex connector set (54599-1019), ensure the
external conductor of the shielded cable is firmly in contact with the ground plate before attaching the connector shell.

*1 Values are taken from manufacturer specifications. When the linear encoder is used with MELSERVO-J5 series servo amplifiers, the
rated speed is the lowest value of either the value indicated in the table or the rated speed of the servo motor.
*2 Values are taken from manufacturer specifications. The length of the encoder cable between the linear encoder and the servo amplifier
should not exceed 30 m.
*3 Select a linear encoder that has a resolution within this range.
*4 When using A/B/Z-phase differential output linear encoders, use the MR-J5-_-RJ_.
*5 When using four-wire type linear encoders in a fully closed loop system, use the MR-J5-_-RJ_. When using four-wire type linear
encoders for the scale measurement function, use the MR-J5-_-RJ_.
The following table shows the servo amplifier connectors used to connect the servo amplifier to a linear encoder.
For the MR-J5-_ servo amplifiers
*1 The MR-J4THCBL03M branch cable is required.
*2 Connect a thermistor to CN2.
*3 The MR-J4FCCBL03M branch cable is required.
*4 If the external encoder communication method is the four-wire type, CN2 cannot be used. Use the MR-J5-_-RJ_.
*5 If the external encoder communication method is the four-wire type, the MR-J5W2-_G_ cannot be used. Use the MR-J5-_G-RJ_.

Fabricating the encoder cable
Fabricate the encoder cable using the MR-ECNM connector set as shown below. The encoder cable may be as long as 30 m.
■Encoder cable 1
*1 Encoder cables that meet the following specifications are recommended.
*2 The signals of pins 3 and 4 of the CN2L connector are as follows.
Pin 3: MR2
Pin 4: MRR2
*3 Do not connect anything to the pins that are marked with a diagonal line. Securely connect the external conductor of the shielded cable
to the ground plate and fix it to the connector shell.
