1LINEAR ENCODER
Precautions
• MR-J5-_G_-RJ and MR-J5-_A_-RJ will be available in the future.
• Oil proof and dust proof measures for the linear encoder is required, more so than for the linear servo motor. Contact each
linear encoder manufacturer for details.
• Use the linear encoder cable introduced in this chapter. Using other than the specified products may cause a malfunction.
• For details of the linear encoder specifications, performance, and assurance, contact each linear encoder manufacturer.
• When the linear encoder is incorrectly installed, an alarm or a position mismatch may occur. In this case, refer to the
following checking points for the linear encoder to check the mounting condition.
Check that the gap between the head and scale is proper.
Check the scale head for rolling and yawing (decrease in rigidity of scale head section).
Check the scale surface 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 for combinations of the linear encoders and servo amplifiers.

• When using a shell kit (36310-3200-008/36310-F200-008) of 3M or connector set (54599-1019) of Molex, securely connect
the external conductor of the shielded cable to the ground plate and fix it to the connector shell.

Fabrication of the encoder cable
Produce the encoder cable using MR-ECNM as shown below. The encoder cable can be produced with a length of up to 30
m.
■Encoder cable 1
*1 Encoder cables that meet the following specifications are recommended.
*2 For the CN2L connector, signals of pin 3 and pin 4 are as follows.
Pin 3: MR2
Pin 4: MRR2
*3 Do not connect anything to the pins shown with a diagonal line. Securely connect the external conductor of the shielded cable to the
ground plate and fix it to the connector shell.

Cable structure
Prepare a cable based on the following configuration diagram.
■For the linear servo motor
• MR-J5-_/MR-J5W_-_G
*1 The connection to CN2C is for the MR-J5-_ 3-axis servo amplifier. MR-J5-_ 2-axis servo amplifier does not have CN2C.
*2 It should be prepared by the customer.
*3 When installing ST741A, ST742A, ST743A, ST744A, or ST748A, a personal computer for the signal adjustment and confirmation, as
well as a software and conversion unit for signal adjustment are necessary. For details, contact Mitutoyo.
*4 For connectors for thermistor signals, change the connection method depending on the customer's system.
