The allowable overhang lengths are based on a configuration where the center of the load mounted on the actuator corresponds to the center of the overhang length.
Caution: � Keep the load moment within the allowable value. If the actuator is operated
under a load equal to or greater than the allowable load moment, abnormal noise or vibration, failure, or shorter life may result. In an extreme case, it may cause flaking on the guide. Do not apply any liquid with temperature lower than the ambient temperature of the actuator installation. It may cause condensation inside the product, which may lead to malfunction.
In case of using the actuator as the Y-axis in a combination of one-sided X-Y,
save the ratings of Ma and Mc moments in 1/2 or less because the base body becomes easy to deform.

2.1 Transportation

[1] Handling of the Robot
Unless otherwise specified, the actuators are packaged individually.
(1) Handling the Packed Unit
Do not damage or drop. The package is not applied with any special treatment that enables it to
resist an impact caused by a drop or crash.
An operator should never attempt to carry a heavy package on their own. Also, use an
appropriate way for transportation.
Keep the unit in a horizontal orientation when placing it on the ground or transporting. Follow the
instruction if there is any for the packaging condition.
Do not step or sit on the package. Do not put any load that may cause a deformation or breakage of the package.
(2) Handling the Actuator After Unpacking
Do not attempt to carry the actuator by holding a cable or move it by pulling a cable. Hold the base part and the bracket when transporting the actuator main body. Do not hit or drop the actuator during transportation. Do not give any excessive force to any of the sections in the actuator.
23
[2] Handling in the Assembled Condition
This is the case when the product is delivered from our factory under a condition that it is assembled with other actuators. The combined axes are delivered in a package that the frame is nailed on the lumber base. The sliders are fixed so they would not accidently move. The actuators are also fixed so the tip of it would not shake due to the external vibration.
(1) How to Handle the Package
Do not hit or drop the package. No special treatment is conducted on this package to endure a
drop or impact on it.
Do not attempt to carry a heavy package with only one worker. Also, have an appropriate
method for transportation.
When hanging up with ropes, support on the reinforcement frame on the bottom of the lumber
base. When bringing up the package with a forklift, also support on the bottom of the lumber base.
Handle with care when putting the package down to avoid impact or bounce. Do not step on the package. Do not put anything on the package that could deform or damage it.
(2) How to Handle after Unpackaged
Fix the slider so they would not accidently move during transportation. If the tip of an actuator is overhanging, have an appropriate way to fix it to avoid shaking due to
the external vibration. In the transportation without the tip being fixed, do not apply any impact with 0.3G or more.
When hanging up with ropes, have appropriate cushioning to avoid any deformation of the
actuator body. Also keep it in stable horizontal orientation. Make a fixture utilizing the attachment holes and the tapped holes on the actuator body if necessary.
Do not attempt to apply load on the actuators or the connector box. Also pay attention not to
pinch cables and bend or deform them forcefully.
[3] Handling in Condition of being assembled in Machinery Equipment (System)
These are some caution notes for when transporting the actuator being assembled in the machinery equipment (system):
Fix the slider so they it would not move during transportation. If the tip of an actuator is overhanging, have an appropriate way to fix it to avoid shaking due to
the external vibration. In the transportation without the tip being fixed, do not apply any impact with 0.3G or more.
When hanging up the machinery equipment (system) with ropes, do not attempt to apply load on
the actuators or the connector box. Also pay attention not to pinch cables and bend or deform them forcefully.

2.2 Installation and Storage • Preservation Environment

[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. Also provide sufficient work space required for maintenance inspection.
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 40C Where the temperature changes rapidly and condensation occurs Where the relative humidity exceeds 85% RH This actuator possesses the water durability of IP67 protection structure. 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 oil (including oil mist or cutting fluid) or chemical
solutions
Where the actuator receives impact or vibration
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] Storage Preservation Environment
The storage and preservation environment should comply with the same standards as those for
the installation environment. In particular, when the machine is to be stored for a long time, pay close attention to environmental conditions so that no dew condensation forms.
Unless specially specified, moisture absorbency protection is not included in the package when
the machine is delivered. In the case that the machine is to be stored and preserved in an environment where dew condensation is anticipated, take the condensation preventive measures from outside of the entire package, or directly after opening the package.
For storage and preservation temperature, the machine withstands temperatures up to 60C for
a short time, but in the case of the storage and preservation period of 1 month or more, control the temperature to 50C or less.
Storage and preservation should be performed in the horizontal condition. In the case it is stored
in the packaged condition, follow the posture instruction if any displayed on the package.

2.3.2 Installing the Main Body
The actuator base has mounting holes. Affix the actuator with M4 hexagon socket-head bolts using these holes. Use of high strength bolts of ISO-10.9 or higher is recommended.
The length of mounting bolts varies depending on the material of the machine frame.
• Steel frame: M4 × 10
• Aluminum frame: M4 × 15
Reamed positioning pin holes are provided in the back face of the base. Use these holes as necessary.
• Reamed hole: 4H7, depth 5mm or less
[Base seating surface] The base seating surface was changed and the width was reduced in order to minimize base deformation caused by the installation surface shape when fixing the actuator with bolts (from August
2010). The installation dimensions stay the same.

2.3.3 Mounting Surface
• For the platform to install the actuator on, ensure the structure has enough stiffness to avoid vibration being generated.
• The surface where the actuator will be mounted should be machined or be equally level and the flatness tolerance between the actuator and the table should be within 0.05mm/m.
• Provide enough space around the actuator to permit maintenance work to be done.
• The slider traveling plane is the reference plane for the actuator base and the lower surface.
• When traveling precision is required, use this as the datum surface for mounting.

2.3.4 Installing the Load to the Slider
There are tapped holes on the top surface of the slider. Affix the work part (transported object) here. There are two reamed holes on the top surface of the slider. Use these reamed holes if repeatability
of attaching and detaching is required. Also, if small tuning such as perpendicularity is required, use one of the reamed holes for the tuning.
Refer to the following table for the screwed depth and reamed depth. Screwing further than indicated
in the table may destroy the tapped hole or lower the reinforcement of the attachment of the work part, result in the drop of the accuracy or an unexpected accident.

Tightening screws
• Use hexagonal socket head bolts for the male threads for installing the base.
• Use of high–tension bolts meeting at least ISO 10.9 is recommended.
• For the effective engagement length between the bolt and female thread, provide at least the applicable value specified below: Female thread is made of steel material � Same length as the nominal diameter Female thread is made of aluminum � 2 times of nominal diameter
Caution: Pay attention when selecting the screw length. Use of a screw with inappropriate
length may destroy a tapped hole or cause a lack in the attachment strength of the transported object, which may result in a cause of an unexpected accident.

3. Connecting with the Controller

For the connection of an actuator to the controller, apply an IAI dedicated controller and dedicated connection cable.
• If the dedicated connection cable cannot be secured, reduce the load on the cable by allowing it to deflect only by the weight of the cable or wire it in a self–standing cable hose, etc., having a large radius.
• Do not cut and reconnect the dedicated connection cable for extension or shorten the cable.
• Do not pull on the dedicated connection cable or bend it forcibly.
• The actuator cable coming out of the motor unit is not meant to be bent. Fix the cable so it would not be bent repeatedly.
Please consult with IAI if you require a different kind of cable than the one supplied.

Warning: 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 operating 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 will 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, presenting 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.
• Have a sufficient radius for bending, and avoid a bend concentrating on one point.
Steel Strap (Piano Wire)
Tie them up softly.
• 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.
• 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.
Do not use spiral tube in any position where cables are bent frequently.
• 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.

33
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 getting cables twined or twisted in the cable track, and also having 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.

* If the actuator are operated back and forth repeatedly over a distance of 30mm or less, the oil film
created by the grease may be broken. As a guide, move the actuators back and forth repeatedly for around 5 cycles over a distance of 50mm or more after every 5,000 to 10,000 cycles. A layer of the grease will recover.

4.2 External Visual Inspection

An external visual inspection should check the following things.
Main unit Loose actuator mounting bolts, other loose items Cables Scratches, proper connections Overall Irregular noise, vibration

4.3 Cleaning

• Clean the exterior as needed.
• Wipe off dirt with a soft cloth.
• Do not use strong compressed air on the actuator as this may force dust into the crevices.
• Do not use petroleum-based solvent on plastic parts or painted surfaces.
• If the unit is badly soiled, apply a neutral detergent or alcohol to a soft cloth, and wipe gently.

4.4 Interior Inspection

After turning off the power, remove the side covers and belt cover to conduct visual checks. Check the following items during interior inspection.
Main unit Loose mounting bolts Guides Lubrication appropriate Soiling Drive belt Scratches Loose Backside of belt cover Lubrication appropriate
The side covers and belt cover can be removed using a hex wrench of 2mm across flats.
Make a visual check of the interior to see if there is any dust or foreign matter in the unit and also check the lubrication condition. Even if the grease you see around the parts is brown, the lubrication is fine as long as the traveling surface appears shiny. If the grease becomes dirty and dull or if the grease has worn away due to extended operating time, lubricate the parts after cleaning them. For details on how to check the drive belt, refer to the check items listed in 4.7.
• Checking the lubrication of the backside of the belt cover Check the lubrication condition of the backside of the belt cover and the belt-cover support (made of resin) at the center of the slider to make sure the frictional resistance between the slider and belt cover is minimized and the slider can move smoothly. If lubrication is not enough, apply the following grease.

4.6 Grease Supply to the Guides

4.6.1 Grease to Apply
Lithium grease No. 2 is used on the guides. The following grease is applied when we ship the unit.
Idemitsu Kosan Daphne Eponex Grease No.2
Other companies also sell a grease similar to this. If ordering from another maker, give the name of this product and request something comparable.
4.6.2 How to Apply the Grease
1) Remove the side covers on both sides.
2) When greasing the guide, use a spatula or grease applicator to squeeze or inject grease into the space between the slider and base, and then move the slider back and forth several times to let the grease spread evenly. Remove excess grease.
3) Follow the same steps to apply grease on the other guide
4) Install the side covers.
Warning: Do not attempt to apply fluorine and lithium grease. When mixed with lithium
grease, not only decrease the grease characteristics, but also may damage the actuator.

4.7 Drive Belt

4.7.1 Inspecting the Belt
Remove the side covers and visually inspect the belt. Durability of the drive belt is affected significantly by the operating condition, and there is no standard guideline as to when the belt should be replaced. Generally, the belt is designed to withstand several million cycles of flexing loads. As a practical guideline, replace the drive belt when any of the conditions listed below is observed:
• The teeth and end faces of the belt have worn significantly.
• The belt has swollen due to deposits of oil, etc.
• Cracks and other damages are found on the teeth or back of the belt.
• The belt has broken.

4.7.3 Checking and Adjusting the Belt Tension
[1] Checking the Tension
As a guideline, belt tension is evaluated by the load needed to deflect the belt by 10mm when the belt is pushed near the stroke center. The table below lists the appropriate loads needed to achieve a 10mm deflection on each belt used at different strokes. If the measured load is less than the applicable value by approx. 20% or more, the belt is loose and its tension must be adjusted. Appropriate loads to achieve 10mm deflection
