LINEAR ENCODER
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. For details, 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.

• 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.
