Handling Precautions

1. Do not set speeds and accelerations/decelerations exceeding the respective ratings.
Do not set speeds and accelerations/decelerations exceeding the respective ratings. It may lead to vibration, failure, or shorter life.
2. Keep the inertial moment, load moment and thrust load within their respective allowable values.
Keep the inertial moment, load moment and thrust load within their respective allowable values. If a load is applied that generates an inertial moment, load moment or thrust load exceeding its allowable value, the life of the actuator may become shorter.
3. Do not operate the hollow rotary actuator repeatedly within a small range, as it may cause grease to shift to and remain in certain areas.
If the hollow rotary actuator is operated repeatedly within a small range, grease may shift to and remain in certain areas and a uniform coating of all areas will be lost. As a result, grease lubrication problems may occur.
4. Do not let foreign matters enter between the output shaft (rotating part) and cylinder (mounted part) of the hollow rotary actuator.
There is a gap of 1 mm between the output shaft (rotating part) and cylinder (mounted part) (see the figure below), so do not let foreign matters, etc., enter this space. It may cause the actuator to fail.
Output shaft (rotating part)
Cylinder
(mounted part)
Gap
5. Do not let the cylinder of the hollow rotary actuator receive a large load.
The cylinder is made of a thin-walled pipe. So that the cylinder will not receive a large load, design a tool to be installed on the output shaft or take other appropriate measure.
8
6. Whenever possible, use the RTC8L and RTC8HL types at speeds of 100 deg/s or more.
If these actuators are operated at low speeds below 100 deg/s, the actuators will move slightly as they move. Even when the operating speed is low, however, vibration will decrease as the speed increases in the low­speed range. Check the actual vibration level at the speeds you intend to use. Take note that the larger the tool, the greater the vibration becomes at ends.
7. Transportation
7.1 Handling the Packed Actuator
When transporting the packed actuator, exercise due caution not to apply impact on the package by dropping it or hitting it against other object.
x A person should never attempt to carry a heavy package on his own. x When setting down the package temporarily, keep it horizontal. x Do not step onto the package. x Do not place on the package a heavy object that may deform the package or article of a shape that
allows the load to be concentrated in one area.
7.2 Handling the Unpacked Actuator
Once the actuator is unpacked, handle the actuator by its frame.
x When transporting the actuator, be careful not to hit it against other object. In particular, pay attention
to the output shaft and cover.
x Do not apply an excessive force to the various parts of the actuator. Pay special attention to the cables. x When unpacking the actuator, exercise due caution not to drop the actuator. It may cause injury or
damage the machine.
x Should you find any part of the actuator missing or damaged during transportation, please contact an

5. Connecting to the Controller
The following explains the wiring method by assuming use of a single axis.

5.1 Wiring

The actuator and controller are connected by the motor cable and encoder cable (genuine part) via connectors.
Motor cable Controller
Actuator
Encoder cable
Example of Connection with XSEL Controller
[For details on the relay cables, refer to 9, “Motor/Encoder Cables.”]
Caution: x In applications where the cables cannot be secured, keep the bending radius of each
cable within the range of cable deflection by the weight of the cable itself, or use a self­standing cable hose or take other measure to keep the bending radius sufficiently large, so as to minimize the load received by the cables.
x Do not cut and extend or shorten the cables or reconnect the cut cable. x Do not pull or forcibly bend the cables, as the lead wires may break.

5. Connecting to the Controller

27
When designing an application system using actuators and controllers, incorrect wiring or connection of each cable may cause unexpected problems such as a disconnected cable or poor contact. This section explains prohibited handling of cables. Read the information carefully to connect the cables properly.
x Do not let the cable flex at a single point.
x Do not let the cable bend, kink or twist.
5. Connecting to the Controller
x Do not let the cable receive a turning force at
a single point.
Steel band (piano wire)
Bundle loosely.
x Do not pull the cable with a strong force.
x When fixing the cable, provide a moderate
slack and do not tension it too tight.
Use a curly cable.
x Do not pinch, drop a heavy object onto or cut
the cable.
Do not use a spiral tube where the cable flexes frequently.
28
z Cautions for use of a cable track
z The actuator cable is not a robot cable, so never
store the actuator cable in a cable track.
Bending radius r
z For the motor and encoder
cables, always use robot cables.
z The bending radius of the cable track must not exceed the minimum
bending radius of the cables. [Refer to 9, “Motor/Encoder Cables.”]
z Do not let the cable get tangled or kinked in a cable track or flexible tube. When bundling the cable, keep a certain
degree of flexibility (so that the cable will not become too taut when bent).
5. Connecting to the Controller
z Do not cause the cables to occupy more than 60% of
the space in the cable track.

z Do not lay signal lines together with circuit lines that
create a strong electric field.

6. Notes on Operation

6.1 Rotary

6.1.1 Backlash and Positioning Accuracy Repeatability
The rotary actuator has backlash (play). If the movement is smaller than the backlash, there may be a possibility that the drive shaft does not rotate. In the case the equipment operates in only one way, it is able to position within the range of the positioning accuracy repeatability unless the gears in the decelerator get free, however, it may move within the range of the backlash while it is stopped, and which may cause variance in the position. Also, when the operation direction is changed, the drive amount may be shortened due to the backlash. In such a case, input the position including the drive amount and the backlash amount.

6. Notes on Operation

6.1.2 Operation Range and Home Return
(1) Range of Operation
The operation range of the rotary equipment is 300 degrees clockwise in the direction of the shaft rotation. There is no mechanical stopper, thus the equipment may exceed the operation range if it is rotated manually by hand while the servo is off. Please note that it may return to the home position in the opposite direction if it is out of the operation range. Refer to (2), "Home Return.") Please use the marking sticker included in the package as the reference of the operation range.
Note) For RT7R, the position data will be displayed as "299.99" even if putting in "300". This is due

(2) Home return
When performing a home-return operation to the rotary, the rotary direction to home-return differs as shown in the figures below due to the position where the shaft is when the home-return operation starts.
1) If the shaft does not detect the sensor at the home-return start, it moves counterclockwise in the
view of the shaft tip ([1]), and it reverses if sensor is detected ([2]), and then stops when the Z­phase is detected. (Refer to Figure 1.)

Caution: The actuator always rotates in the same direction during a home return.
If the actuator is of a standard specification, it always performs a home return in the counterclockwise direction from any position outside the range of Z-phase search shown in the figure. The actuator does not take a shortcut. If a cable is passed through the opening, pay attention to the load on the cable. An excessive load may sever its lead wires.

6.2.2 Brake
x The actuator’s brake is designed to hold the work part in place. Do not use it to decelerate the actuator
or actuate an emergency stop. x To release the brake manually, use the brake switch on the controller. (Note) If the actuator must hold the work part in place, check the holding torque.

8. Options

8.1 Limit Switch

Normally during the home return operation, the slider contacts the stopper and reverses, and then detect Z-phase (“push method”). The home limit switch (L) is used to cause the actuator to reverse not upon contact, but using a proximity sensor. The limit switch is a standard feature on both the rotary type and hollow rotary type.
8.2 Brake
The brake is a mechanism to hold the work part and thereby prevent it from dropping and sustaining damage when the power or servo is turned off on the actuator installed on its side. This brake is designed to hold the work part in place. Do not use it to decelerate the actuator or actuate an emergency stop. The model name for the brake is “B.”

8.3 Reversed-home Specification

If the reversed-home specification is selected, the actuator rotates in the counterclockwise direction, which is opposite the direction in which the standard specification actuator would rotate, as the actuator moves to a + position. Also during a home return, the actuator rotates in the opposite direction compared to the standard specification. The model name for the reversed-home specification is “NM.”

10.2 Visual Inspection of the Exterior

In the visual inspection of the exterior, check the following items.
Actuator Loosening of actuator mounting bolts, etc.
Cables Scratches, proper connection of connectors
Overall Noise, vibration x With the hollow rotary type, grease that has been applied to the gears may drip depending on
the environment. Clean the areas dirtied by grease or add grease, as necessary.

10.3 Exterior Cleaning

x Clean the exterior of the actuator as necessary. x Use a soft cloth, etc., to wipe off dirt. x Do not blow compressed air onto the actuator too strongly, in order to prevent dust from entering the
actuator through small openings and gaps.
x Do not use petroleum solvent as it may damage the resin parts and coated surfaces. x To clean stubborn soiling, moisten a soft cloth, etc., with neutral detergent and wipe gently.

10.4 Adding Grease to the Hollow Rotary Gears

On the hollow rotary actuators (RTC8L, RTC8HL, RTC10L, RTC12L), add grease to the gears periodically according to the periodic inspection intervals.
(1) Applicable grease The actuators have been charged with the following gear grease prior to shipment from IAI.
Kyodo Yushi AC-D No.2
During the maintenance, use lithium grease No. 2. Corresponding products include those listed below.
Showa Shell Sekiyu Albania Grease No. 2
Mobil Sekiyu Mobilux 2
10. Maintenance/Inspection
41
(2) How to add grease
[1] Remove the screws mounting the rear cover (countersunk machine screw M2.6 x 6).
Pull the rear cover slightly from the actuator frame. (Do not forcibly pull the cables inside.)
Round terminal
[2] While turning the gears, apply grease from the rear opening just enough to coat the bottom of the
teeth. (As the input shaft is turned, the output gears turn.) Thereafter, turn the grease several times in both directions to let the grease spread evenly.
10. Maintenance/Inspection
You should see the gears through this opening. Apply grease on the tooth surface.
42
Turn.
If the actuator has a brake, connect the controller to release the brake.
[3] Install and mount the front cover and rear cover.
Be careful not to pinch the cables when mounting the rear cover.
Warning: x Never use fluorine grease. If fluorine grease is mixed with lithium grease, grease
function will drop and the mechanical parts will be damaged.
x Do not add grease any more than necessary. Excess grease may flow to the electronic
components and cause malfunction.
x The encoder phase has been adjusted precisely for detection of rotational angles and
home signals. Never touch the encoder, as it may lead to a failure.
x Be careful not to pinch the cables when affixing the rear cover. Store the cables neatly
in the space above without them resting on top of one another. Do not forcibly tighten the screws when the panel is not fully seated.
