skids. The same applies for lifting the package with a forklift; please ensure that the forks are placed under the
skids.
x When setting the package down, do not let the package receive an impact upon contacting the floor.
(2) Handling 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.
x Secure the slider so that it does not move unexpectedly during transport.
x 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.
x 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.
x Make sure the belts support the actuator load by its base by using appropriate cushioning materials.
x 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.
x 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.

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.
x Where the actuator receives radiant heat from strong heat sources such as heat treatment furnaces
x Where the ambient temperature exceeds the range of 0 to 40qC
2. Installation
x Where the temperature changes rapidly and condensation occurs
x Where the relative humidity exceeds 85% RH
x Where the actuator receives direct sunlight
x Where the actuator is exposed to corrosive or combustible gases
x 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)
x Where the actuator is subject to splashed water, oil (including oil mist or cutting fluid) or chemical
solutions
x Where the actuator receives impact or vibration
If the actuator is used in any of the following locations, provide sufficient shielding measures:
x Where noise generates due to static electricity, etc.
x Where the actuator is subject to a strong electric or magnetic field
x Where the actuator is subject to ultraviolet ray or radiation
[2] Storage • Preservation Environment
x 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.
x 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.
x For storage and preservation temperature, the machine withstands temperatures up to 60qC for a short
time, but in the case of the storage and preservation period of 1 month or more, control the temperature to
50qC or less.
x 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.

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 be 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 4.7 Procedure for Stainless Steel Sheet
Replacement and Adjustment.]
47
2.3.2 Installation of Main Unit
䎃
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.
䎃
Also consider enough space necessary for maintenance work such as actuator replacement and inspection.
There are datum surfaces for attachment on the base.
The flatness of the slider movement is designed to be 0.05mm/m at maximum to the datum surface.
2. Installation
On the rear side of the actuator, there are tapped holes and through holes for attachment and reamed hole
and oblong hole for positioning. See the appearance drawings for the details of the position and diameters.
[Refer to 5. External Dimensions]
Utilize the reamed holes when repeatability in the attachment after detaching is required. However, when
small tunings such as the perpendicularity is required, consider such things like to use one reamed hole.
[1] Using the Tapped Holes on the Bottom of the Base
This actuator has the tapped holes for mounting so it can be fixed from the bottom of the base.
(Note that tapped hole size depends on the model. Please see the diagrams below and 13,1 "External
Dimensions.")
Also, there are reamed holes and a slotted hole for positioning pins.

3. Connecting with Controller
As the connection cable for the controller and RCP4 (this actuator), use the IAI-dedicated controller and
dedicated connection cable.
This section explains the wiring method for a single axis.
x 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.
x Do not cut and reconnect the dedicated connection cable for extension or shorten the cable.
x Do not pull on the dedicated connection cable or bend it forcibly.
x 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.
*) □□□ indicates the cable length. Up to 20m can be specified.
Example) 080 = 8 m
55
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 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.
3. Connecting with Controller
• 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.
• Do not bend the cable in the area from the connector tip inward to 150mm on both ends.
CB-CA-MPAƑƑƑ, CB-CA-MPAƑƑƑ-RB
150mm150mm
• Have a sufficient radius for bending, and avoid a bend concentrating on one point.
Steel Strap
(Piano Wire)
Tie them up softly.
56
• 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.
3. Connecting with Controller
• 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.
57
• 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.
• If using a cable track, arrange the wiring so that there is no entanglement or kink of the cables in the
cable carrier or flexible tube, and do not bind the cables so that the cables are relatively free. (Arrange
the wiring so the cables are not to be pulled when bent.)
3. Connecting with Controller
• The occupied volume rate for the cables, etc., inside the cable track should be 60% or less.

4. Maintenance Inspection
4.1 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 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.
4.2 External Visual Inspection
*1
4. Maintenance Inspection
An external visual inspection should check the following things.
Main unit Loose actuator mounting bolts, other loose items
Cables Scratches, proper connections
Stainless sheet Scratches
Overall Irregular noise, vibration
Ɣ 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.
Ɣ 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.
4.3 Cleaning
Ɣ Clean exterior surfaces as necessary.
Ɣ Use a soft cloth to wipe away dirt and buildup.
Ɣ Do not blow too hard with compressed air as it may cause dust to get in through the gaps.
Ɣ Do not use oil-based solvents as they can harm lacquered and painted surfaces.
Ɣ To remove severe buildup, wipe gently with a soft cloth soaked in a neutral detergent or alcohol.
59
4.4 Internal Inspections
Turn OFF the power, remove the side cover and have a visual inspection.
When inspecting the interior, check the following items.
Main unit Loose mounting bolts, other loose items
Guide section Lubrication, buildup
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.
1) Loosen the screws on the side cover and detach the side cover.
2) Check inside.
4. Maintenance Inspection
3) After finishing the inspection, assemble back in the reverse order. When attaching the side cover, push
up the stainless steel sheet firmly so excess force would not be applied to the stainless steel sheet.
Caution: 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.
Change in the attached condition may cause the sheet to be mounted unevenly or impact the
product life. In such cases, please contact IAI Sales Engineer Department.
Keep in mind that the edges of the stainless sheet can cause injuries. Always wear gloves
when working on it.
4.5 Internal Cleaning
Ɣ Use a soft cloth to wipe away dirt and buildup.
Ɣ Do not blow too hard with compressed air as it may cause dust to get in through the gaps.

Apply grease on both sides.
Wipe off the excess grease at the end.
62
(3) To grease ball screws, first clean, then put some grease on your finger and apply while moving the slider
back and forth.
In this process, pay attention to the stainless steel sheet so that you would not touch and make it
deformed.
When finished, wipe off excess grease.
(4) Attach the side covers after grease supply is finished.
If you touch the edge of the stainless sheet in the attaching process, the sheet may get damaged or
wavy which result in shortening life or earlier wear-out.
To avoid touching the edge of the sheet, insert a spacer (approximately 0.1 to 0.2mm) between the
sheet and cover to push up the sheet, and then push in the cover.
4. Maintenance Inspection
Caution: x Do not damage the stainless steel sheet by bending it forcefully during the check inside.
Also you may get hurt on the edge of the stainless steel sheet. Wear gloves when you work
on it.
The front cover is supporting the ball screw. Do not detach it.
If the front cover loses its tuned condition, it may cause an increase of slider resistance,
shorten production life and abnormal noise due to the center of the axis being off the right
position.
x In case the grease got into your eye, immediately go see the doctor to get appropriate care.
After finishing the gease supply work, wash your hands carefully with water and soap to
rinse the grease off.

(2) Caution for the stainless steel sheet tension
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

(6) Slide the slider in the whole range of the stroke for several times to ensure there is no touch of the slider
to the stainless steel sheet, and check the tension at the same time.
For those such as low lead type or brake-equipped type that cannot be moved with hand, turn on the
power supply to the controller and move the slider in approximately 20mm/s using either the teaching
pendant or PC software.

Screw
The replacement period cannot be determined in general because the durability of the deceleration belt can
be greatly influenced by the conditions of operation.
It generally has life of hundreds of times for bending movement.
The timing belt requires replacement regularly under the following conditions as a reference since
degradation such as abrasion proceeds as the time passes for usage.
x When remarkable abrasion is confirmed on the teeth or edges of the belt
x When the belt is swelled for such reasons as oil being attached on
x When damage is confirmed such as crack on the tooth or back of the belt
Also, since it is difficult to confirm the degradation of the core wires to retain the strength of the teethed belt
by visual or looseness caused by being elongated, it is recommended to set regular replacement periods in
advance in case the product is used under such conditions that gives the core wires great fatigue due to
high acceleration and deceleration speed.

3) Adjust the belt tension.
Hand a cable band (thin string) on the edge of the motor unit and pull it on a tension gauge with the specified
load (specified value of the belt tension).
When the load reached the specified, tighten the screws with a 2.5mm-sized (SA5R/SA6R) or 3mm-sized
(SA7R) hex wrench to hold the unit in the place.

4) Tighten the three screws to hold the pulley cover with a 1.5mm-sized hex wrench to attach the pulley
cover.
The mechanical life of the actuator is represented by that of the guide receiving the greatest moment load.
The “rated load” is one factor that relates to the traveling life.
There are two types of “rated load,” namely “static rated load” and “dynamic rated load.”
x “Static rated load” : Load which, when applied to a stationary actuator, leaves a minor pressure mark
on the contract surface.
x “Dynamic rated load” : Load which applies after a specified traveling distance under a load based on a
specific probability of survival at which the guide does not break
Guide manufacturers indicate the life of a guide using a dynamic rated load when the provability of survival
after 50 km of traveling is 90%.
In the case of general industrial machinery, however, you should understand the specific life also for the
purpose of maintenance. Also, the life of a guide has a sufficient allowance relative to a radial load, and
receives the greatest impact by a moment load offset from the center of the guide.
The life is designed to ensure a traveling life of 5,000 km under a load corresponding to the allowable load
moment and at a load coefficient of 1.2 (safety factor).
[For the dynamic allowable load moment, refer to 2, “Specification”]
The calculation formula for allowable load moment at a traveling life of 5,000 km is shown below:
