Handling Precautions
1. Do not set a speed or acceleration/deceleration exceeding the
applicable rating.
Do not set a speed or acceleration/deceleration exceeding the applicable rating. Doing so may result in
vibration, failure or shorter life. If an acceleration/deceleration exceeding the rating is set, creep may occur
or the coupling may slip.
2. Keep the load moments to within the allowable value.
Keep the load moments to within the allowable value. If a load exceeding the allowable load moment is
applied, the life of the actuator may be reduced. In an extreme case, even flaking may occur.
3. Keep the overhang length to within the allowable value.
Keep the overhang length of the load to within the allowable value. If the overhang length exceeds the
allowable value, vibration or noise may occur.
4. Grease film may run out after back-and-forth operations over a short
distance.
Grease film may run out if the actuator is moved back and forth continuously over a distance of 30 mm or
less. As a guide, perform a back-and-forth operation five times or over a distance of 50 mm or more after
a back-and-forth operation over such short distance has been repeated 5,000 to 10,000 times. This will
restore oil film.
5. Turn on the servo after confirming that the slider or rod is away from the
mechanical end.
If the servo is turned on when the slider or rod is near the mechanical end, pole phase detection may not
be performed correctly and an pole non-confirmation error or excitation detection error may occur.
Move the slider or rod away from the mechanical end before turning on the servo.
6. Make sure to attach the actuator properly by following this operation
manual.
Using the product with the actuator not being certainly retained or affixed may cause abnormal noise,
vibration, malfunction or shorten the product life.

7. Transportation
7.1Handling the Unassembled Actuator
When transporting the unassembled actuator alone, pay attention to the items specified below.
7.1.1 Handling the Packed Unit
Unless otherwise specified, single-axis actuators are shipped in individual packaging.
Please handle packages carefully during transport to ensure that product is not damaged by bumping or
dropping.
Never attempt to move heavy packages by yourself.
Always set packages down on a level surface.
Never climb on top of packages.
Never place heavy objects or objects where the load is concentrated in one place on top of packages,
as this may cause deformation.
7.1.2Handling the Actuator After Unpacking
Do not carry an actuator by a cable or attempt to move it by pulling the cable.
When transporting the unassembled actuator, pay attention to the items specified below.
When unpacking the actuator and handling it thereafter, always hold it by the base.
Never hold an actuator by the stainless sheet.
Be careful not to bump the actuator into anything when moving it, paying particular care to the side
covers.
Do not attempt to force any part of the actuator. Take particular care not to force the stainless sheet.
Warning: Never hold the actuator by the stainless sheet.
Supplement) For the names of each part of the actuator,
refer to 1, "Part Names.”
9
7.2Handling the Actuator Assembly
When transporting the actuator with its axes already assembled, take note of the following items.
7.2.1Shipping from IAI Already Assembled
After assembly at IAI, your machine undergoes a shipping inspection, is packed in a crate with skids, and
finally shipped.
If any of the combined actuators is a slider, the slider is securely fastened in place to prevent unexpected
movement during shipping. Combined units have the ends of their actuators fastened so as to prevent
them from moving significantly due to external vibration.
The crate is not designed to withstand dropping or collision. Please handle it carefully. It is also not
built to have items stacked on it, so please avoid placing heavy objects on top of the crate.
When lifting the package using belts or the like, be sure to pass the belts around the reinforcement
frames under the skids. The same applies for lifting the package with a forklift; please ensure that the
forks are placed under the skids.
When setting the package down, do not let the package receive an impact upon contacting the floor.
7.2.2Handling After Unpacking
Please adhere to the following instructions when handling the assembled unit, whether it was shipped preassembled at IAI or assembled on your site.
Secure the slider so that it does not move unexpectedly during transport.
If the end of the actuator is protruding, fasten it down properly so that it does not move significantly due
to external vibration. When transporting the assembly without the ends of the actuators fastened, do
not subject the assembly to an impact of 0.3 G or more.
When using belts or the like to lift an assembly consisting of an actuator and peripheral equipment,
make sure the belts are not passed around the actuator itself or otherwise do not touch the actuator.
Make sure the belts support the actuator load by its base by using appropriate cushioning materials.
Lift the end of the Y-axis with a separate belt, ensuring that the assembly remains level. At this time,
also make sure the load is not placed on the screw cover.
Make sure the load is not placed on the brackets, covers, or connector box.
Also make sure the cables are not pinched or deformed excessively.
7.3Handling after Assembly with Peripheral Equipment
When the machine assembled at IAI is transported as an assembly, also follow the handling precautions
in 5.2.2, “Handling after Unpacking.”

9. Installation
Caution:1. When the unit is installed vertically oriented, attempt to put the motor up unless there
is a special reason. Putting the motor on the lower side would not cause a problem
in an ordinary operation. However, it may rarely cause a problem, when it is not
operated for a long period, depending on the surrounding environment (especially
high temperature), caused by the grease being separated and the base oil flowing
into the motor unit.
2. Can be installed sideways or ceiling mount, but the actuators must be checked
daily. If the actuator is installed sideways or ceiling mount, the stainless sheet may
sbe slacked or displaced. If the actuator is used continuously while the stainless
sheet is slacked or displaced, the stainless sheet may break or other problems may
occur. Check the actuator daily and if the stainless sheet is found slacked or
displaced, make installation adjustment of the stainless sheet. [Refer to 13.9
Replacement (for models with slider cover).]

9.2Installation of Actuator
9.2.1Installation of RCA2-SA2AC and SA2AR
This actuator has the screw holes for mounting so it can be fixed from the rear side.
Also, there are a reamed hole and a slotted hole for positioning pins.
9.2.2Installation of RCA2-SA3C, SA4C, SA5C, SA6C, SA3R, SA4R, SA5R and SA6R
The surface to mount the main unit should be a machined surface or a plane that possesses an equivalent
accuracy and the flatness should be within 0.05mm. Also, the platform should have a structure stiff enough
to install the unit so it would not generate vibration or other abnormality.
This actuator has the screw holes for mounting so it can be fixed from the rear side.
(Note that tap hole size depends on model. Please see diagrams below and 2, "External Dimensions.")
The actuator also contains reamed holes for use with positioning pins.
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.
The length of thread engagement should be 1.8 times more than the nominal diameter, and pay
attention not to stick the screw out inside the actuator.
Caution: Be careful when selecting the bolt length. If bolts of inappropriate lengths are used, the
tapped holes may be damaged, actuator mounting strength may become insufficient, or
contact with driving parts may occur, resulting in lower precision or unexpected accidents.
9. Installation
47
9.3Mounting Surface
The platform to install the actuator should possess a structure that ensures enough stiffness,
The side and bottom faces of the base provide reference surfaces for slider travel. When it is
necessary that the slider moves in a highly precise fashion, ensure that the device is installed at
the direction that is based on the position of these surfaces.
9. Installation
Follow the diagram below when installing the device using the reference surface.

9.4Installation of the Load
A
Please attach the load to the device using the tap holes in the slider.
The process for attaching these to the main unit is similar to the installation process of the main
unit. Use of high-tension bolts meeting at least ISO-10.9 standard is recommended for mounting.
The table below shows the recommended tightening torque.
There are two reamed holes on the slider, so if you need to be able to secure and detach the load
multiple times, please use these holes. Also, if you require precision in your attachment, such as a
right angle, use one of the reamed holes to make fine adjustments.
*When using reamed holes, we recommend using an H7 pin. Also, do not force the pin into
the hole. Instead, press it gently in until it fits.
For exact thread depth and reamed hole depth, please see the table below.
Do not tighten the mounting screws to a torque beyond the applicable torque specified in the table
below. Doing so may damage the tapped holes.

10.Connecting with Controller
Both for the controller itself and for the connection cable between the controller and actuator (RCA2), use
a dedicated IAI controller and dedicated connection cable.
This section explains the wiring method for a single axis.
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.
Please consult with IAI if you require a different kind of cable than the one supplied.

11. Notes on Operation
57
11.2 Adjusting the Home Position
*1
The actuator home position can be adjusted by changing parameter
please do the following.
[1] Verify the home position by performing a home return operation.
[2] Move the actuator to the desired position, verify the distance between the old and new positions, and
adjust the parameter accordingly. The parameter can be set to a positive value in the direction of
movement. (It cannot be set to a negative value.)
[3] Increasing the offset amount restricts the movement range by the amount of the increase. If you set an
offset greater than 1 mm, please reset the stroke soft limit.
*1 ACON controller: No. 22, home return offset distance
ASEL controller: Parameter No. 12 for each axis, home preset value
ASEP controller: No. 16, home return preset value
AMEC controller: No. 16, home return preset value
. In order to make adjustments,
11.3 Changing the Home Position Direction
To change the home position direction after delivery, it is necessary to change the movement direction
parameter. Please contact with IAI if you need to do this.
Warning:
The encoder serves not only to detect the actuator’s position and the home position signal, it also plays a
crucial role in phase switching for the AC servo power line, and its phase is adjusted precisely. Never
touch the encoder in order to change the home position.
11. Notes on Operation
58
11.4 Stainless Sheet Section
xThe stainless sheet is attached by absorbtion to the side cover. If the environment contains high levels
of iron filings or other magnetic matter, this may become absorbed between the stainless sheet and
the rubber and cause malfunction. For that reason, avoid usage in such an environment.
xKeep adhesive, paint, and other viscous material off the stainless sheet. Such material sticking to the
stainless sheet can lead to defective slider operation and stainless sheet damage.
xBe careful to avoid localized force on the stainless sheet. Such force could deform the stainless sheet
and cause malfunctions.
Also, during installation and transport, do not hold on to or press on the stainless sheet. Doing so
could damage the stainless sheet.
11. Notes on Operation
59
12. Life
One factor that affects the traveling life of an actuator is “Rated Load.”
There are two types of rated loads: “Static Rated Load” and “Dynamic Rated Load.”
x “Static Rated Load”: Load applied while the actuator is stopped, as a result of which minor
pressure marks are left on the contact surface
x“Dynamic Rated Load”: Load under which the actuator can travel for a specified distance and still
meet a specified probability of survival defined by no damage to its guide.
Manufacturers of guides indicate the life of each guide by a dynamic rated load based on a probability of
survival (no damage to the guide) of 90% after 50 km of traveling.
With industrial equipment, however, dynamic rated loads must be defined based on longer traveling
distance of 5,000 km to 10,000 km given the moving speed, operating ratios and other operating
conditions of these equipment.
Also note that guides are generally designed with a sufficient life against radial loads. Moment loads that
are applied at positions away from the guide center are most damaging to guides.
The traveling life is calculated by assuming that the actuator travels 5,000 km while receiving the
allowable load moment, based on a load coefficient of 1.2.
[For the allowable dynamic load moment, refer to 6, “Specifications.”]
The formula for calculating the allowable dynamic load moment corresponding to a traveling life of 5,000
km is shown below.

13. Maintenance Inspection
13.1 Inspection Items and Schedule
Follow the maintenance inspection schedule below.
It is assumed that the equipment is operating 8 hours per day.
If the equipment is running continuously night and day or otherwise running at a high operating rate,
inspect more often as needed.
*1 If grease is found degraded as a result of interior check, add grease
*2 Grease film may run out if the actuator is moved back and forth continuously over a distance of 30 mm or less. As a guide,
perform a back-and-forth operation five times or so over a distance of 50 mm or more after a back-and-forth operation over such
short distance has been repeated 5,000 to 10,000 times. This will restore oil film.
13.2 External Visual Inspection
{
{
{{
{{{
{
{{{
An external visual inspection should check the following things.
Main unit Loose actuator mounting bolts, other loose items, buildup
Cables Scratches, proper connections
Stainless sheet Scratches, slacked
OverallIrregular noise, vibration
y If the stainless sheet is slacked, make adjustment to remove the slack as necessary.
y As a rule of thumb, the stainless sheet should last for about 5000 km of slider motion. However, under
certain conditions, the stainless sheet may need to be replaced earlier.
Generally, replacing the stainless sheet will require that you bring the unit to our plant or have one of
our technicians come to your plant to perform the replacement.
y If the actuator is installed vertically, certain conditions may cause grease to drip from the guide. Please
ensure that proper cleaning is performed and grease is replenished.
13. Maintenance Inspection
61
13.3 Cleaning
y Clean exterior surfaces as necessary.
y Use a soft cloth to wipe away dirt and buildup.
y Do not blow too hard with compressed air as it may cause dust to get in through the gaps.
y Do not use oil-based solvents as they can harm lacquered and painted surfaces.
y To remove severe buildup, wipe gently with a soft cloth soaked in a neutral detergent or alcohol.
13.4 Adjusting the Stainless Sheet
If the actuator stroke is 400 mm or more, check the stainless sheet for slacking, etc., as necessary. If the
stainless sheet is found slacked, adjust the stainless sheet.
[For the stainless sheet adjustment procedure, refer to 13.9, “Replacing/Adjusting the Stainless Sheet.”]
13. Maintenance Inspection
62
13.5 Internal Inspections
Turn off the power and inspect visually after turning up or removing the stainless sheet in the case of
stainless sheet types. With reversing types, inspect visually after removing the reversing bracket.
When inspecting the interior, check the following items.
Main unit Loose mounting bolts, other loose items
Guide section Lubrication, buildup
Belt
(Reversing type)
Visually inspect the interior of the equipment. Check whether dust or other foreign matter has gotten inside
and check the lubrication state.
The lubrication may have turned brown. This is not a problem as long as the travel surfaces shine as
though they are wet.
If the grease is mixed with dust and does not have a shiny appearance, or if the grease has lost its
efficacy due to prolonged use, then clean each section and reapply grease.
The procedure for internal inspections is outlined below. Refer to 13.8 for inspection and adjustment of the
belt.
"Slider type" --- Steps [2] through [5] are only necessary if the cover is attached. If you do not have a cover,
only do step [1].
[1] Move the slider to the home position side.
[2] Remove the cover.
[3] Remove the sheet retainer screws.
[4] Peek under the stainless sheet and check the interior.
[5] When the checks are completed, reassemble the parts by following the same procedure in reverse.
Cautions for attached cover:
When checking inside the equipment, be careful not to forcibly bend the stainless sheet or scratch it.
Do not tug on the stainless sheet or in any way attempt to reposition it.
If the sheet is repositioned, it may not be even which may shorten its service life. Should this happen,
adjust the stainless sheet by referring to the replacement instructions.
Keep in mind that the edges of the stainless sheet can cause injuries. Always wear gloves when working
on it.
