5. If return operations are continued over a short distance, they may rapidly

degrade the film of grease.

Continuous return operation within a distance less than 30mm may cause the grease film to

degrade rapidly.

As a guideline, in every 5,000 to 10,000 cycles, have approximately 5 cycles of return operation

over a 50mm distance or more to regenerate the oil film. Continued use of the actuator in that

state may lead to breakdown.

In extreme cases, flaking may occur on the guide or ball screw.

6. Do not attempt to have sliders collide with an obstacle at high speed.

This may damage the coupling or other mechanical parts.

7. For Double Slider Specification (Option Code: W) in Reversed-home

Specification (Option Code: NM), make sure to have the home-return

operation conducted after joining the driver slider and free slider.

8. In some conditions of environment of use, postures of installation and
conditions of operation, the base oil separated from the grease may come out
of ROBO Cylinder.
It is recommended to have a protection in case the peripheral devices could
get influence of the base oil.

International Standard Compliance

Caution

The maximum speed may not be achieved when the stroke or movement distance is
short or when acceleration/deceleration is set low.
Setting at or below the minimum speed may lead to abnormal noise or unstable speeds.
Do not attempt to set below the minimum speed.
The minimum speed can be calculated with the equation below.
Minimum speed [mm/s] = ball screw lead [mm/r] ÷ 16384 [p/r] x 1000 [1/s]

2. Installation

2.2 Installation and storage/preservation environment

Usage is possible in environments of pollution degree 2 or equivalent.

Pollution degree 2: Environment in which generally only nonconductive pollution occurs,

but temporary conductive pollution may occur due to condensation

(IEC 60664-1)

Installation Environment

The actuator should be installed in a location other than those specified below.

In general, the installation environment should be one in which an operator can work without

protective gear.

● Where the actuator receives radiant heat from strong heat sources such as heat treatment

furnaces

● Where the ambient temperature exceeds the range of 0 to 40°C

● Where the temperature changes rapidly and condensation occurs

● Where the relative humidity exceeds 85% RH

● Where the actuator receives direct sunlight

● Where the actuator is exposed to corrosive or combustible gases

● Where the ambient air contains a large amount of powder dust, salt or iron (at level exceeding

what is normally expected in an assembly plant)

● Where the actuator is subject to splashed water, oil (including oil mist or cutting fluid) or

chemical solutions

● Where the actuator receives impact or vibration

● Where the altitude is more than 2,000m

Also, provide sufficient work space for the following maintenance and inspection:

● Space to replenish grease

● Space to replace the motor

If the actuator is used in any of the following locations, provide sufficient shielding measures:

● Where noise generates due to static electricity, etc.

● Where the actuator is subject to a strong electric or magnetic field

● Where the actuator is subject to ultraviolet ray or radiation

2.2 Installation and storage/preservation environment

Horizontal installation Vertical installation

Sideway installation Ceiling mount installation

Caution

When installing the unit vertically, keep the motor on top to the greatest extent
possible.
If the motor is installed on the bottom, the grease may separate due to long-term disuse,
causing the base oil to flow into the motor part. The controller and motor/encoder may
break down due to the entry of the base oil.

2-6

2. Installation

Precautions regarding stainless steel sheet

● During installation and transport, do not grasp or press on the stainless steel sheet.
Otherwise, this may lead to stainless steel sheet damage.

● Although lateral or ceiling installation is possible, it may cause slackness or

misalignment of the stainless steel sheet.
Continued usage in this orientation may lead to damage to the stainless steel sheet.

● Adjust the stainless steel sheet if slackness or misalignment occurs.

● Keep adhesive, paint, and other viscous material off the stainless steel sheet.

Such material adhering to the stainless steel sheet can lead to defective slider
operation or sheet damage.
Avoid installation in environments of this kind, or take safety measures to prevent
adhesion.

2.3 How to Install

2-7

2. Installation

Installation surface

● The body mounting surface should be a machined surface or a plane with similar accuracy,
with flatness within 0.05mm/m.

● The mounting frame should have a structure rigid enough to prevent the generation
of vibration, etc.

● Also consider enough space necessary for maintenance work such as actuator replacement
and inspection.

● The bottom surface and both side surfaces of the body base serve as the reference surfaces

for slider running accuracy.
Use these surfaces as the reference surfaces for mounting when running accuracy is required.

Caution

For wiring, please follow the warnings stated below. When constructing a system as the machinery
equipment, pay attention to the wiring and connection of each cable so they are conducted properly.
Not following them may cause not only a malfunction such as cable breakage or connection failure,
or an operation error, but also electric shock or electric leakage, or may even cause a fire.

Use dedicated cables of IAI indicated in this instruction manual. Contact us if you wish to have a

change to the specifications of the dedicated cables.

Make sure to turn the power off in the process of power line or cable connection or disconnection.

Do not attempt to cut a dedicated cable with connectors on both ends to extend, shorten or re-joint it.

Hold the dedicated cable to avoid mechanical force being applied to the terminals and connectors.

Use a cable pipe or duct to have an appropriate protection when there is a possibility of mechanical
damage on a dedicated cable.

In case a dedicated cable is to be used at a moving part, make sure to lay out the cable without
applying any force to pull the connector or extreme bend on the cable. Do not attempt to use the
cable with a bending radius below the allowable value.

Make certain that the connectors are plugged properly. Insufficient connection may cause an
operation error, thus it is extremely risky.

Do not lay out the cables to where the machine runs over them.

Pay attention to the cable layout so it would not hit peripherals during an operation. In case it does,
have an appropriate protection such as a cable track.

When a cable is used hanging on the ceiling, prevent an environment that the cable swings with
acceleration or wind velocity.

Make sure there is not too much friction inside the cable storage equipment.

Do not apply radiated heat to power line or cables.

Caution

Have a sufficient radius for bending, and avoid a bend concentrating on one point.

Do not let the cable bend, kink or twist.

Do not pull the cable with a strong force.

Pay attention not to concentrate the twisting force to one point on a cable.

Tie them up softly.

Caution

Do not pinch, drop a heavy object onto or cut the cable.

When a cable is fastened to affix, make sure to have an appropriate force and do not tighten too

much.

PIO line, communication line, power and driving lines are to be put separately from each other and

do not tie them together. Arrange so that such lines are independently routed in the duct.

Do not use spiral tube in any position

where cables are bent frequently.

Caution

Follow the instructions below when using a cable track.

If there is an indication to the cable for the space factor in a cable track, refer to the wiring instruction

given by the supplier when storing the cable in the cable track.

Avoid the cables to get twined or twisted in the cable track, and also to have the cables move freely

and do not tie them up. (Avoid tension being applied when the cables are bent.)

Do not pile up cables. It may cause faster abrasion of the sheaths or cable breakage.

4.1 Precautions for maintenance and inspection work

Make sure to read the following precautions before conducting any maintenance or inspection

work.

Caution

Do not climb on or put anything on the actuator.
Otherwise, this may lead to accidental falling, injury or damage to the product due to
falling objects, product loss of function or performance degradation, or shortening of
product life.
Before releasing the brake, make sure to check there is nothing that will interfere with
moving parts within the operation range.
The slider may fall, possibly injuring the operator or people nearby and damaging the
actuator, workpiece or equipment.

Caution

Check that the power to the actuator is OFF before conducting any maintenance or
inspections.
Be careful not to lose the cover or any removed screws.
Be sure to return the product to the original condition after maintenance and inspection
work.
Mounting in an incomplete state may cause injuries or damage to the product.
Do not modify, disassemble/assemble, or use maintenance parts not specified on your
own discretion under any circumstances.

4.1 Precautions for maintenance and inspection work

4-2

4. Maintenance and Inspection

Caution

The grease film may run out if the actuator performs return operation continuously over a

distance of 30mm or less. As a guideline, every 5,000 to 10,000 cycles, have

approximately 5 cycles of return operation over a 50mm distance or more to regenerate

the oil film.

The ball screw or guide may be damaged if the oil film runs out.

Notice

● First, be sure to wipe off the old grease, and then supply new grease.

● The degradation speed of grease may differ depending on the operating environment

(temperature, humidity and ambient atmosphere).

It is recommended to shorten the grease supply period if the actuator is used under poor

environmental conditions such as high temperatures, high humidity or dusty

atmospheres.

● Also, it is recommended to improve the environmental conditions in case the grease

changes color notably due to poor operating conditions.

● Base oil may separate from the grease due to the mounting orientation or operating

conditions.

Base oil may also leak from the inside of the actuator to the exterior through gaps.

Check visually for oil drips when supplying grease.

● An actuator stored for 6 months or more may suffer from grease degradation.

Supply grease before the start of use.

→For details, refer to "4.5 Greasing method".

Move the slider back and forth in the stroke range after supplying grease so it spreads out
evenly in the area.

• Confirm that the ball tracks on the ball screw and guide look glossy with oil of grease.
Supply grease again if it is not spread enough.

• Wipe off excess grease.

Caution

Supplying too much grease may increase sliding resistance and load to the motor, resulting

in a drop of performance.

Also, excess grease on the ball screw may be splashed around in the ambience.

Caution

Do not damage the stainless steel sheet by bending it forcefully during work.
Keep in mind that the edges of the stainless steel sheet can cause injuries. Always wear

gloves when working on it.

The front bracket is supporting the ball screw. Do not detach it.
If the front bracket loses its tuned condition, it may cause an increase of driving

resistance, shortened life of each component or abnormal noise due to the center of the

axis being off the right position.

In case the grease got into your eye, wash it with clean water for 15 minutes and

immediately go see the doctor to get appropriate care.

After finishing the grease supply work, wash your hands carefully with water and soap to

rinse the grease OFF.

Names of the Parts

Caution

Degradation and wear-out of the stainless steel sheet relies on its tension of attachment.

If the stainless steel sheet is pulled with a huge force and the gap between the sheet and

the slider cover is large, there is a risk of metal fatigue.

On the other hand, if the tensile strength is too low, the stainless steel sheet would

interfere with the back side of the slider cover and make dust to be generated.
