• 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. Page 5 Compatible linear encoder list
1.1 Shield procedure of CN2, CN2A, CN2B, and CN2C
side connectors
• 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.
