In this Instruction Manual, the safety instruction levels are classified into "WARNING" and "CAUTION".
WARNING
Indicates that incorrect handling may cause hazardous conditions,
resulting in death or severe injury.
CAUTION
Indicates that incorrect handling may cause hazardous conditions,
resulting in medium or slight injury to personnel or may cause physical
damage.
Note that the CAUTION level may lead to a serious consequence according to conditions.
Please follow the instructions of both levels because they are important to personnel safety.
What must not be done and what must be done are indicated by the following diagrammatic symbols.
Indicates what must not be done. For example, "No Fire" is indicated by .
Indicates what must be done. For example, grounding is indicated by .
In this Instruction Manual, instructions at a lower level than the above, instructions for other functions, and so
on are classified into "POINT".
After reading this Instruction Manual, keep it accessible to the operator.

CAUTION
More careful measures against oil and dust must be taken for the linear encoder
than the linear servo motor. For details, contact each linear encoder
manufacturer.
POINT
Always use the linear encoder cable introduced in this chapter. Using other
products may cause a malfunction.
For details of the linear encoder specifications, performance and assurance,
contact each linear encoder manufacturer.
A linear encoder communication method cannot be used depending on the
software version of the servo amplifier. Refer to section 1.1 for combinations of
the communication methods and software versions.
When the linear encoder is incorrectly installed, an alarm or a position mismatch
may occur. In this case, refer to the following general checking points for the
linear encoder to confirm the installation.
Check that the gap between the head and scale is proper.
Check the scale head for rolling and yawing (looseness of scale head section).
Check the scale surface for contamination 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 section 1.1 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.

MR-J4-_GF_(-RJ) servo amplifiers with software version A1 or later are

Note 1. We recommend the following specifications encoder cables.
Wiring length
Number of LG and P5 connections
(when the output cable is 3 m or less)
Cable size
to 5 m 1-pair
to 10 m 2-pair
AWG 22
to 20 m 3-pair
to 30 m 5-pair
2. For wiring to the thermistor of the linear servo motor, refer to "Linear Servo Motor Instruction Manual".
3. Do not connect anything to the pins shown as
. Especially, pin 10 is for manufacturer adjustment. If it is connected with
any other pin, the servo amplifier cannot operate normally. Referring to POINT of chapter 1, securely connect the external
conductor of the shielded cable to the ground plate and fix it to the connector shell.
