5. Transporting and Handling
5.1 Handling the Actuator
5.1.1 Handling the Packed Unit
Unless otherwise specified, each actuator (axis) is shipped individually. Please make sure that the shipping
box is not dropped or subjected to strong impact during transport.
• Operators should not carry heavy shipping boxes by themselves.
• If the shipping box is left standing, it should be in a horizontal position.
• Do not climb on top of the shipping box.
• Do not place heavy objects which may deform the shipping box or objects with concentrated loads on top of
the box.
5.1.2 Handling the Actuator after It is Unpacked
Lift the actuator up by the base to remove it from the packing.
• When carrying the actuator, make sure not to bump it. Take particular care with the front cover and motor
cover.
• Do not exert excessive force on any part of the actuator.
• Be careful not to cause the cables to receive a tensile force.
• Be careful when handling the stainless sheet
The stainless sheet is designed very thin (thickness: 0.1mm) in order to ensure flexibility. Therefore, the stainless sheet is easily dented or scratched. Once dented or scratched, the stainless sheet may break during use.
Warning: Do not press the sheet
directly with hands.
*Please refer to Section 4 above for the names of the actuator parts.
9
5.2 Handling the Actuator Assembly
Make sure to the following instructions when transporting an assembly of actuator axes.
5.2.1 Condition of Shipment from IAI (Assembled)
The actuators you have ordered are assembled at IAI, after which the assembly receives a shipping inspection and is shipped in an outer frame with skids. The assembly is packed with sliders securely affixed so that they will not move unexpectedly during transportation. In the case of a combined unit, the actuator ends are secured to prevent swinging due to external vibration.
• The package is not designed with special considerations for protection against impact due to dropping or
collision, so please handle the package with care. Also, do not place any heavy object on the outer frame, as it is not strong enough to withstand loads.
• When suspending the package using ropes, etc., pass the ropes from underneath the reinforcement frames
at the bottom of the skids. When lifting with a forklift, also place the forks underneath the skids.
• Set down the package carefully so as not to apply impact to the assembly or cause it to bounce.
After unpacking, handle the actuator assembly correctly by observing the instructions given below.
5.2.2 Handling after Assembly with Peripheral Equipment
When transporting the actuators that have been assembled with peripheral equipment either at IAI or at your site, observe the instructions given below.
• Secure each slider to prevent unexpected movement during transportation.
• If any actuator end is protruding, secure it to prevent swinging due to external vibration.
• If the actuator ends are not secured, do not apply any impact force exceeding 0.3G during transportation.
• When suspending the actuator-assem bled peripheral equipment using ropes, etc., make sure that the ropes
do not contact the actuators directly.
• Pass the ropes over appr opriate cushion materials, and make sure the loads from the ropes will be received
directly by the base of each actuator.
• Secure the end of the Y-axis using a separate rope to maintain the axis in a stable horizontal position. At this
time, be careful not to apply loads on the screw cover.
• Be careful not to allow the brackets, covers and connector box of each actuator to receive loads. Also protect
the cables from pinching or excessive deformation.
10
6. Operating and Storage Environment
6.1 Operating Environment
The actuator should be set up in an environment, which meets the following criteria:
• Avoid direct sunlight.
• Avoid radiant heat from strong heat sources such as a furnace.
• Ambient temperature should be 0 - 40°C.
• The humidity should be less than 85% and there should be no condensation.
• Avoid exposure to corrosive or combustible gases.
• The area should have very little dust and be suitable for normal assembly operation.
• Avoid exposure to oil mist or fluids used in cutting.
• The unit should not be subject to impact or vibrations.
• Avoid extreme electromagnetic waves, ultraviolet rays and radiation.
• This product is not intended to be used in a chemical environment.
In general, the environment should be one in which an operator can work without protective equipment or protective clothing.
Work space needed for maintenance/inspection
6.2 Storage Environment
The storage environment should be similar to the operating environment. In addition, you must take precautions against condensation if the unit is to be stored for a long period of time. Unless there are special instructions, we do not include moisture absorption agents when shipping the unit. If you are storing the unit where condensation might occur, then you must treat the entire package from outside of the package or treat the unit itself after it is unpacked to prevent condensation. The unit can withstand up to 60°C during a short storage interval but only up to 50°C if the storage period is longer than one month.

7. Installation
Notes on Installation
The stainless sheet is designed very thin (thickness: 0.1mm) in order to ensure flexibility. Therefore, the stainless sheet is easily dented or scratched. Once dented or scratched, the stainless sheet may break during use. When installing the stainless sheet, make sure to the following points:
1. Do not press the sheet directly with hands.
2. Protect the sheet from dents by making sure not to drop tools and workpieces onto the sheet.
3. Do not allow powder dust or iron powd er to generate around the stainless sheet. If it generates, wipe the stainless sheet fully after operation to remove all particles attached to the sheet. If the actuator is operated with the stainless sheet carrying foreign particles, those particles may enter the slider and damage the sheet or cause the sheet to deform, lift or present other problems. For SS and HS, the stainless sheet is held in place by means of a magnet on the side covers. Since metal particles, iron powder or other magnetic substances in ambient air are likely to attach to the magnets, make sure to the surrounding environment.

(Note) When reinstalling the side covers, do not let them contact the end faces of the stainless sheet. This
may damage or bend the stainless sheet, causing the sheet to deteriorate or wear quickly. Therefore, install the side covers and check for bending according to the procedure below.
(1) To prevent the side covers from contacting
the end faces of the sheet, insert a shim (approx. 0.1 to 0.2mm) between the sheet and each cover to provide a slight allowance, and gently push in the cover.
(2) Remove the slider covers and check to see
that the right and left clearances between the slider and sheet are nearly equal and no bending is created.
(3) Finally, move the slider back and forth several times along the entire stroke to check that the slider does not
contact the sheet.

7.2 Mounting Surface
• The mounting table should have sufficient rigidity to avoid generating vibration.
• 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.
• Provide sufficient space around the actuator to permit maintenance work to be performed.
• The side and bottom faces of the actuator base provide the reference planes for slider travel.
• When traveling precision is required, use these surfaces as the reference planes for mounting.
Caution: As shown above, the side faces of the base provide the reference planes for slider travel. When
precision is required, use these surfaces as the reference planes for mounting.
When using the base as the reference planes for mounting the actuator to the machine frame, follow the machining dimensions shown below.

7.3 Clamp Screws
• The male screws for mounting the base should be M4 for SA5C, M5 for SS7C/SA6C/SA7C, and M8 for SS8C/HS8C. (Use hexagon socket-head bolts.)
• For the bolts, we recommend high strength bolts of ISO-10.9 or higher.
• When using a foot base to attach to a mounting table, use the special washer made for high strength bolts that comes with the actuator if the bolt is M8 or larger. This is unnecessary for M6 or smaller bolts. Do not use a common spring washer.
• The recommended screw torque is given below.

7.4 Installing the Load to the Slider
• Tapped holes are provided on the slider for installing the load. The method of clamping varies according to how to mount the main body.
• In case of moving the main body with the slider secured, use the same tapped holes on the slider.
• Please use two reamed holes on the slider when repeatability of mounting and dismounting is required. When fine adjustment of the squareness is necessary, use only one reamed hole to allow adjustment.

8. Wiring Cable
• In an application where the cable cannot be anchored, try to place the cable so that it sags only under its own weight or use a self-standing type cable as a large radial wire duct to limit the load on the cable.
• Never cut and/or reconnect the cables supplied with the product for the purpose of extending or shortening the cable length.
• The cables supplied with an actuator offer excellent flexibility, but they are not robot cables. If the cables are to be stored in a movable cable duct (cable bearer, etc.), use robot cables.
For cable modification, please contact your IAI sales representatives.

11. Maintenance
11.1 Maintenance Schedule
Perform maintenance work according to the schedule below. The schedule is set assuming eight hours of operation a day. When the operation time is long such as a 24-hour operation, shorten the maintenance intervals as needed.
Visual inspection Check interior Grease supply Start of operation After 1 month of operation After 6 months of operation After 1 year of operation Every 6 months thereafter Every 1 year
11.2 Visual Inspection of the Machine Exterior
Check the following items when carrying out visual inspection.
Body Loose mounting bolts? Cables Damage to cables or connection to connector box? Stainless sheet Damage or foreign deposit? General Unusual noise or vibrations?
11.3 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 solvents on plastic parts or painted surfaces since such solvents damage them.
• If the unit is badly soiled, apply a neutral detergent or alcohol to a soft cloth, and wipe gently.
22
11.4 Interior Inspection
Turn off the power, remove the side covers, and then visually inspect the interior. Check the following items during interior inspection.
Body Loose mounting bolts? Guides Lubrication appropriate? Soiling? Ball screw Lubrication appropriate? Soiling?
How to inspect the interior:
1) Remove both side covers.
Use an Allen wrench of 1.5mm across flats for SA5C/SA6C/SA7C/SS7C or an Allen wrench of 2.00mm across flats for SS8C/HS8C.
Make a visual check of the interior to see if there is any dust or foreign matter in the unit and check the lubrication. Even if the grease you see around the parts is brown, the lubrication is fine as long as the traveling surface appears shiny.
2) 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.
3) When the inspection/maintenance work is complete, install the side covers.
Tightening torque: SA5C/SA6C/SA7C/SS7C: Thin-head screw M3 × 6 - 87.2N·cm (8.90kgf·cm)
SS8C/HS8C: Thin-head screw M4 × 6 - 204N·cm (20.8kgf·cm)
When installing the side covers, do not let them contact the end faces of the stainless sheet. This may damage or bend the stainless sheet, causing the sheet to deteriorate or wear quickly. To prevent this problem, insert a shim (approx. 0.1 to 0.2mm) between the sheet and each cover between the sheet and each cover to provide a slight allowance, and gently push in the cover.
Caution: When checking the interior, be careful not to bend or scratch the stainless sheet. Wear protective
gloves when handling the stainless sheet, because it has sharp edges that may cause accidental cuts. The front cover is supporting the ball screw; so do not disassemble the front cover. If the front cover is misaligned, the shaft centers may become offset, thus increasing the traveling resistance, reducing the service life of each part, or generating noise.
23
11.5 Internal Cleaning
• 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, neutral detergent or alcohol.
Caution: Do not use flushing oil, molybdenum grease or anti-rust lubricant.
When grease is soiled with a large amount of foreign substances, wipe off the dirty grease and then apply new grease.
11.6 Lubricating the Guides and Ball Screw
11.6.1 Other than Cleanroom Specification
(1) What Grease to Use on the Guides The following grease is used 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. Comparable products include the following:
Showa Shell Oil Albania Grease No. 2 Mobil Oil Mobilux 2
(2) What Grease to Use on the Ball Screw The following grease is used when we ship the unit. This grease offers excellent properties such as low heat generation, and is suitable for lubricating ball screws.
Kyodo Yushi Multemp LRL3
Warning: Never use any fluorine-based grease. It will cause a chemical reaction when mixed with a
lithium-based grease and may cause damage to the actuator.
24
11.6.2 Cleanroom Specification
(1) What Grease to Use on the Guide and Ball Screw
For guides and ball screw, a urea-based grease of low-dust-raising type which has stable torque characteristics and superior lubrication performance as well as the anti-rust effect equivalent to that of a lithium-based grease is used. The following grease is used when we ship the unit:
Kuroda Precision Industries C Grease
Caution: Never use grease for the standard specification. It may allow dust to generate.
Warning: Never use any fluorine-based or lithium-based grease. It will cause the grease to lose its
lubrication performance and may damage the actuator or reduce cleanliness performance when mixed with an urea-based grease.
25
11.6.3 How to Apply Grease
1) 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 grease spread evenly. Apply grease on the guides on both sides. Remove excess grease.
2) When greasing the ball screw, clean the ball screw, apply grease using a finger, and then move the slider
back and forth several times to let the grease spread evenly. At this time, be careful not to deform the stainless sheet by accidentally touching the sheet. Remove excess grease.
3) Install the side covers.
Tightening torque: SA5C/SA6C/SA7C/SS7C: Thin-head screw M3 × 6 87.2N·cm (8.90kgf·cm) SS8C/HS8C: Thin-head screw M4 × 6 204N.cm (20.8kgf.cm) Refer to 3) in 11.4, “Interior Inspection,” for notes on installing the side covers.

11.7 Replacing/Adjusting the Stainless Sheet
[Items Required for Replacement]
• Replacement stainless sheet
• Clearance-checking tool (a regular slider cover with holes)
(This tool is available from IAI’s Sales Engineering Section. If you are replacing the stainless sheet, please contact us to make a rental arrangement or purchase the tool.)
• Allen wrench set • Phillips screwdriver • Scale
[Note on Stainless Sheet Tension]
Deterioration and wear of the stainless sheet is affected by its tension. If the stainless sheet is too tight, excessive clearances will be created between the sheet and slider covers and the sheet may undergo a fatigue failure. If the stainless sheet is too loose, the sheet will contact the back of the slider covers and generate shaving. Therefore, use a dedicated adjustment tool to properly adjust the tension of the stainless sheet so that the clearances between the stainless sheet and slider covers conform to the specified dimension.

After the slider covers have been removed
Caution: Remove the slider covers slowly and gently. If the actuator is installed on the ceiling or oriented
vertically or horizontally on its side, place a plastic bag, etc., underneath the slider covers so as not to lose the coil springs and spacers in case they drop off.

2) Remove the stainless-sheet retainer screws on both sides and pull out the stainless sheet.
3) Guide a new stainless sheet into the slider.
4) Hold the stainless sheet in place, and affix the retainer plates and screws.
At this time, securely tighten the screws only on the motor side, and leave the screws on the counter-motor side loose.
How to prevent the stainless sheet from lifting (SA5C/SA6C/SA7C)
Slightly bend the stainless sheet downward near the center of the mounting holes so that the sheet can be
held securely.
5) Install the clearance-checking tool.

6) Adjust the tension of the stainless sheet. [1] While looking through the center ope ning in the clearance-checking tool, move the stainless sheet on the
loose end in the directions of arrows until the clearance between the top face of the stainless sheet and the back of the clearance-checking tool falls within the specified range.
[2] When the stainless sheet has been properly positioned, tighten the screws on the loose end to a level that
the stainless sheet no longer moves.
Move the stainless sheet in the directions of arrows to adjust the tension.
While looking through the center opening, check the clearance between the top face of the stainless sheet and the back of the clearance-checking tool. (If the clearance is within the specified tolerance range, the tension is appropriate even when the clearance varies along the entire stroke or between right and left.)
(Standard) (Cleanroom specification)
30
[3] Move the slider and check the tension of the stainless sheet along the entire stroke.
If the conditions in Checkpoints 1 and 2 are not satisfied, loosen the screws and readjust the position and tension of the stainless sheet again from [1].
Note) If the condition in Checkpoint 2 cannot be met after the readjustment, try installing the stainless sheet
in the reverse direction or placing it upside down. If the stainless sheet is still not adjusted properly, replace it with a new sheet.
[4] When proper clearances are obtained between the slider body and stainless sheet and an absence of
contact between the two is confirmed, tighten the two screws on the loose end alternately, and then finally tighten all screws to a uniform torque to securely affix the stainless sheet. If the screws are not tightened uniformly, the sheet may meander or lift.
[5] Remove the clearance-checking tool and install the slider covers. Note) Again, make sure not to lose the coil springs and spacers.
Checkpoint 1: Check if the clearance between the top face of the stainless sheet and the back of the clearance-checking tool falls within the specified range along the entire stroke.
Checkpoint 2: Look through the peripheral openings and confirm that the stainless sheet edges do not contact the slider body. Move the slider back and forth at least three times over the entire stroke to ensure the edges do not contact the slider. The sheet may move during the slider strokes, but slight movement is acceptable as long as the offset does not increase and the sheet does not contact the slider. If the stainless sheet contacts the slider, repeat the adjustment from [1].
The stainless sheet is not perfectly straight, but it bends to the right and left slightly. It is impossible to adjust the right and left clearances perfectly uniform. Slight variation in clearance in the stroke direction or between the right and left is acceptable, as long as the stainless sheet edges do not contact the slider body over the entire stroke.
