Precautions

1. Do not attempt to establish the settings for the speed and acceleration/deceleration above the allowable range.
An operation with speed and acceleration/deceleration beyond the allowable range may cause an abnormal noise, vibration, malfunction or shortened life.
2. Back and forth operation in short distance may wear out the oil film of the grease.
If the actuators are moved back and forth continuously over a short distance of 30 mm or less, grease film may run out. As a guide, move the actuators back and forth repeatedly for around 5 cycles over a distance of 50 mm or more after every 5,000 to 10,000 cycles. Keep using the actuators with the grease worn out may cause malfunction. If it is extreme, flaking may occur on the guide.
3. Do not attempt to apply a rotary torque
Doing so may damage the internal component such as the rod stopper, and may result in an operation failure.
4. The allowable load moment for the flat type should be within the allowable range.
If the robot is operated under a load equal to or greater than the allowable load moment, abnormalnoise or vibration, failure, or shorter life may result. In an extreme case, flaking may occur. If it is extreme, flaking may occur on the guide.
5. For the model equipped with the home-position check sensor (Model: HS), do not attempt to have the home return speed setting faster than the initial setting at the time the product was delivered.
Because the home-position check sensor switch is stored inside the body on the motor end, it may get damaged if the setting is made faster than the initial.
6. Make sure to attach the actuator properly by following this instruction 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. Ensure use of the product in the specified conditions, environments and ranges.
An operation out of the guarantee may cause a drop in performance or malfunction of the product.

1.2.6 Allowable Load Moment of Actuator
(1) Rod Type
x The actual load should not exceed the value specified in the catalog. x Be sure to align the shaft center of the rod and the moving direction of the load.
x Lateral load may cause damage or breakdown of the actuator. x If the rod may receive lateral load, provide a guide or other appropriate mechanism to support the
actuator in the moving direction of the load.
1. Specications Check
x Do not allow the rod (slide shaft) to receive rotational torque.
* Doing so may damage the internal parts.
Tighten the nut at the tip of the rod, while securely holding the rod using a wrench of size 17 (RA4) or 22 (RA5).

1.3 Option

1.3.1 Brake Type (Model: B)
The brake is a mechanism designed to prevent the rod from dropping on a vertically installed actuator when the power or servo is turned OFF. Use the brake to prevent the installed load, etc., from being damaged due to the falling rod.
1.3.2 Reversed–home Specification (Model: NM)
The standard home position is on the motor side. This is the type to indicate when the operation direction is required to be in the same as the coordinate system of the device that the actuator is mounted on.
Caution: The home position is adjusted at the factory before shipment. If you wish to change
the home after the delivery of your actuator, you must return the actuator to IAI for adjustment. Contact our sales office or an agent near you.
1.3.3 Foot Bracket (Model: FT)
It is a metal part to be attached on the bottom of the actuator to affix with screws from top side.

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.

This chapter explains how to install the actuator on your mechanical system.
2.3.1 Installation of Main Unit
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.
Also consider enough space necessary for maintenance work such as actuator replacement and inspection. On the base there is a datum surface prepared for the attachment slotted holes. On the back side of the actuator, there are attachment tapped holes, through holes, positioning reamed holes and slotted holes. For the details of the positions and dimensions, check in the appearance drawings. [Refer to 6. External Dimensions.] When repeatability in re-attaching is required after it is detached, utilize the reamed holes. Please note, however, that a consideration is necessary such as to use only one point on the motor side of the reamed holes when a fine-tuning such as perpendicularity is required.

3. Connecting with Controller
As the connection cable for the controller and RCS2 (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.

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.
• 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.
3. Connecting with Controller
• 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.
• Have a sufficient radius for bending, and avoid a bend concentrating on one point.
Steel Strap (Piano Wire)
Tie them up softly.
65
• 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.
66
• 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.
Power Line
Duct
I/O Line (Flat Cable, etc.)
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.

4.5 Procedure for Belt Replacement and Tuning

Applicable Untis : RCS2-RA4R, RA5R
4.5.1 Inspection of the Belt
For inspection work, detach the cover of a pulley case and carry it out by visual.
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
