Safety Instructions

Please read the instructions carefully before using the equipment.

Do not attempt to install, operate, maintain or inspect the equipment until you have read through this

Instruction Manual and appended documents carefully and can use the equipment correctly. Do not use the

equipment until you have a full knowledge of the equipment, safety information and instructions.

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.

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 POINT of chapter 1, securely connect the external

conductor of the shielded cable to the ground plate and fix it to the connector shell.
