Note 4) Impact resistance:

No malfunction occurred when the actuator was tested with a drop tester in both an axial direction and a perpendicular direction to the lead screw. (The test was performed with the actuator in the initial state) Vibration resistance: No malfunction occurred in a test ranging between 45 to 2000 Hz when the actuator was tested in both an axial

direction and a perpendicular direction to the lead screw. (The test was performed with the actuator in the initial state) Note 5) The "Power consumption" (including the controller) is for when the actuator is operating. Note 6) The "Standby power consumption when operating" (including the controller) is for when the actuator is stopped in the

set position with no applied force in the direction of the actuator movement. Note 7) The "Momentary max. power consumption" (including the controller) is for when the actuator is operating.

This value can be used for the selection of the power supply. Note 8) Only applies to actuators supplied with a lock. Note 9) For the actuator with lock, please add the power consumption for the lock.

3.3 Step data setting

(1)

Refer to the operation manual of the controller (LEC series) for details. This operation manual specifies the electric slide table, if an actuator other than the electric slide table is used, refer to the operation manual of each type of actuator and controller (LEC series) regarding the description of step data.

Caution

The actuator body and controller are sold as a package.

If when only the actuator is purchased separately, confirm that the combination of the controller, which you have and the actuator is compatible.

<Be sure to check the following before use.> (1) Check that actuator label for model number.

This matches the controller.

(2) Check Parallel I /O configuration matches (NPN or PNP).

Positioning operation

In the positioning operation, the electric slide table transfers to and stops at the target position.

The following image shows the set items and operation.

When the table of actuator reaches the range of the target position, the output signal 【INP】 (in position) is outputted. When the table of actuator enters the range of 【in position】, the INP output signal turns on.

2. There is a possibility of dangerous sudden action by the product if sliding parts of machinery are twisted due to external forces etc.

In such cases, human injury may occur, such as by catching hands or feet in the machinery, or damage to the machinery itself may occur. Design the machinery should be designed to avoid such dangers.

3. A protective cover is recommended to minimize the risk of personal injury.

If a driven object and moving parts of the product are in close proximity, personal injury may occur. Design the system to avoid contact with the human body.

4. Securely tighten all stationary parts and connected parts so that they will not become loose.

When the product operates with high frequency or is installed where there is a lot of vibration, ensure that all parts remain secure.

5. Consider a possible loss of power source. Take measures to prevent injury and equipment damage even in the case of a power source failure.

6. Consider behavior of emergency stop of whole system. Design the system so that human injury and/or damage to machinery and equipment will not be caused, when it is stopped by a safety device for abnormal conditions such as a power outage or a manual emergency stop of whole system.

7. Consider the action when operation is restarted after an emergency stop or abnormal stop of whole system.

Design the system so that human injury or equipment damage will not occur upon restart of operation of whole system.

8. Disassembly and modification is prohibited

Do not modify or reconstruct (including additional machining) the product. An injury or failure can result.

9. Do not use the stop signal, "EMG" of the controller and stop switch on the teaching box as the

emergency stop of system.

The stop signal, "EMG" of controller and the stop switch on the teaching box are for decelerating and stopping the actuator.

Design the system with an emergency stop circuit which is applied relevant safety standard separately.

10. When using it for vertical application, it is necessary to build in a safety device.

The table may fall due to the weight of work. The safety device should not interfere with normal operation of the machine.

Caution

1. Operate within the limits of the maximum usable stoke.

The product will be damaged if it is used with the stroke which is over the maximum stroke. Refer to the specifications of the product.

2. When the product repeatedly cycles with partial strokes, operate it at a full stroke at least once a day or every 1000 strokes.

Otherwise, lubrication can run out.

3. Do not use the product in applications where excessive external force or impact force is applied to it.

The product can be damaged. Each component that includes motor is made with accurate tolerance. So even slightly deformed or miss-alignment of component may lead operation failure of the product.

- 36 -

4. Returning to origin cannot be done during the operation.

It cannot be done during positioning operation, pushing operation and pushing.

5. Refer to a common auto switch /matter (Best Pneumatics No 2) when an auto switch is built in and used.

6. When conformity to UL is required, the electric actuator and controller should be used with a UL1310 Class 2 power supply.

5.2 Mounting

Warning

1. Install and operate the product only after reading the Operation Manual carefully and

understanding its contents.

2. Observe the tightening torque for screws. Unless stated otherwise, tighten the screws to the recommended torque for mounting the product.

3. Do not make any alterations to this product.

Alterations made to this product may lead to a loss of durability and damage to the product, which can lead to human injury and damage to other equipment and machinery.

4. When using external guide, the guide axis should be parallel to the actuator axis.

There will be damage/excessive wear on the lead screw if the external guide is not parallel.

5. When an external guide is used, connect the moving parts of the product and the load in such a way that there is no interference at any point within the stroke.

Do not scratch or dent the sliding parts of the product tube or piston rod etc., by striking or grasping them with other objects. Components are manufactured to precise tolerances, so that even a slight deformation may cause faulty operation.

6. Prevent the seizure of rotating parts.

Prevent the seizure of rotating parts (pins, etc.) by applying grease.

7. Do not use the product until you verify that the equipment can operate properly.

After mounting or repair, connect the power supply to the product and perform appropriate functional inspections to check it is mounted properly.

8. Cantilever

When the actuator is operated at high speed while it is fixed at one end and free at the other end (flange type, foot type, double clevis type, direct mount type), a bending moment may act on the actuator due to vibration generated at the stroke end, which can damage the actuator. In such a case, install a support bracket to suppress the vibration of the actuator body or reduce the speed so that the actuator does not vibrate. Use a support bracket also when moving the actuator body or when a long stroke actuator is mounted horizontally and fixed at one end.

9. When mounting the actuator or attaching to the work piece, do not apply strong impact or large moment.

If an external force over the allowable moment is applied, it may cause looseness in the guide unit, an increase in sliding resistance or other problems.

10. Maintenance space

Allow sufficient space for maintenance and inspection.

5.3 Handling

Warning

1. Do not touch the motor in operation.

The surface temperature of the motor can increase to approx. 90 conditions. This temperature increase may also be caused by energizing alone. As it may cause burns, do not touch the motor when in operation.

C to 100oC due to operating

- 37 -

2. If abnormal heating, smoking or fire, etc., occurs in the product, immediately shut off the power supply.

3. Immediately stop operation if abnormal operation noise or vibration occurs.

If abnormal operation noise or vibration occurs, the product may have been mounted incorrectly. Unless operation of the product is stopped for inspection, the product can be seriously damaged.

4. Never touch the rotating part of the motor while in operation.

5. When installing, adjusting, inspecting or performing maintenance on the product, controller and related equipment, be sure to shut off the power supply to them. Then, lock it so that no one other than the person working can turn the power on, or implement measures such as a safety plug.

In the case of the actuator that has a servo motor (24VDC), the “motor phase detection step" is done by inputting the servo on signal just after the controller power is turned on.

The “motor phase detection step” moves the table/rod for the distance of the one screw-lead as the maximum. (The motor rotates in the reverse direction if the table hits an obstacle such as the end stop damper.) Take the “motor phase detection step” into consideration for the installation and operation of this actuator.

Caution

The product is set in parameters for shipment. If it is combined with a different parameter, failure can result.

2. Check the product for the following points before operation.

a) Damage to power supply line and signal line. b) Looseness of the connector to each power line and signal line. c) Looseness of the actuator /cylinder and controller /driver mounting d) Abnormal operation e) Emergency stop of the total system

3. When more than one person is performing work, decide on the procedures, signals, measures and resolution for abnormal conditions before beginning the work. Also, designate a person to supervise work other than those performing work.

4. Actual speed of the product will be changed by the workload.

Before selecting a product, check the catalog for the instructions regarding selection and specifications.

5. Do not apply a load, impact or resistance in addition to a transferred load during return to origin.

In the case of the return to origin by pushing force, additional force will cause displacement of the origin position since it is based on detected motor torque.

6. Do not remove the nameplate.

7. Operation test should be done by low speed. Start operation by predefined speed after confirming there is no trouble.

1. Avoid use in the following environments.

a. Locations where a large amount of dusts and cutting chips are airborne. b. Locations where the ambient temperature is outside the range of the temperature specification (refer

to specifications).

c. Locations where the ambient humidity is outside the range of the humidity specification (refer to

specifications). d. Locations where corrosive gas, flammable gas, sea water, water and steam are present. e. Locations where strong magnetic or electric fields are generated. f. Locations where direct vibration or impact is applied to the product. g. Areas that are dusty, or are exposed to splashes of water and oil drops. h. Areas exposed to direct sunlight (ultraviolet ray).

2. Do not use in an environment where the product is directly exposed to liquid, such as cutting oils.

If cutting oils, coolant or oil mist contaminates the product, failure or increased sliding resistance can result.

3. Install a protective cover when the product is used in an environment directly exposed to foreign matters such as dust, cutting chips and spatter.

Play or increased sliding resistance can result.

4. Shade the sunlight in the place where the product is applied with direct sunshine.

5. Shield the product if there is a heat source nearby.

When there is a heat source surrounding the product, the radiated heat from the heat source can increase the temperature of the product beyond the operating temperature range. Protect it with a cover, etc.

6. Grease oil can be decreased due to external environment and operating conditions, and it

deteriorates lubrication performance to shorten the life of the product.

[Storage]

Warning

1. Do not store the product in a place in direct contact with rain or water drops or is exposed to harmful gas or liquid.

2. Store in an area that is shaded from direct sunlight and has a temperature and humidity within

the specified range (-10°C to 60°C and 90%RH or less No condensation or freezing).

3. Do not apply vibration and impact to the product during storage.

5.5 Maintenance

Warning

1. Do not disassemble or repair the product.

Fire or electric shock can result.

2. Before modifying or checking the wiring, the voltage should be checked with a tester 5 minutes

after the power supply is turned off.

Caution

1. Maintenance should be performed according to the procedure indicated in the Operating Manual.

Improper handling can cause an injury, damage or malfunction of equipment and machinery.

- 39 -

2. Removal of product

When equipment is serviced, first confirm that measures are in place to prevent dropping of work pieces and run-away of equipment, etc, and then cut the power supply to the system. When machinery is restarted, check that operation is normal with actuators in the proper positions.

[Lubrication]

Caution

1. The product has been lubricated for life at manufacturer, and does not require lubrication in

service.

When lubrication is applied, special grease must be used. / See “6.5 How to spreading grease” on p.48

5.6 Precautions for actuator with lock

Warning

1. Do not use the lock as a safety lock or a control that requires a locking force.

The lock used for the product with a lock is designed to prevent dropping of work piece.

2. For vertical mounting, use the product with a lock.

If the product is not equipped with a lock, the product will move and drop the work piece when the power is removed.

3. "Measures against drops” means preventing a work piece from dropping due to its weight when the product operation is stopped and the power supply is turned off.

4. Do not apply an impact load or strong vibration while the lock is activated.

If an external impact load or strong vibration is applied to the product, the lock will lose it’s pushing force and damage to the sliding part of the lock or shortening of lifespan can result. The same situations will happen when the lock slips due to a force over the thurst of the product, as this accelerates the wear to the lock.

5. Do not apply liquid or oil and grease to the lock or its surrounding.

When liquid or oil and grease is applied to the sliding part of the lock, its pushing force will reduce significantly.

6. Take measures against drops and check that safety is assured before mounting, adjustment and inspection of the product.

If the lock is released with the product mounted vertically, a work piece can drop due to its weight.

7. When the actuator is operated manually (when SVRE output signal is off), supply 24DCV to the [BK RLS] terminal of the power supply connector.

If the product is operated without releasing the lock, wearing of the lock sliding surface will be accelerated, causing reduction in the holding force and the life of the locking mechanism.

8. Do not supply 24VDC power supply constantly to the [BK RLS(Lock release)] terminal.

Stop supplying 24VDC power supply to the [BK RLS(Lock release) terminal during normal

operation. If power is supplied to the [BK RLS] terminal continuously, the lock will be released, and workpieces may be dropped at stop (EMG).

/Refer to the operation manual of LEC (controller) for details of wiring.

6. Electric actuators / Common precautions

6.1 Design and selection

Warning

1. Do not apply a load in excess of the actuator specification.

A product should be selected based on the maximum pay load and allowable moment. If the product is used outside of the operating limit, eccentric load applied to the guide will become excessive and have adverse effects such as creating play at the guide, degraded accuracy and shortened product life.

2. Do not use the product in applications where excessive external force or impact force is applied to it.

This can lead to premature failure of the product..

6.2 Handling

Caution

1. INP output signal

1) Positioning operation

When the product comes within the set range by step data [In position], output signal will be turned on. Initial value: Set to [0.50] or higher.

2) Pushing operation

When the pushing force exceeds the [TriggerLV] value the INP ( In position) output signal is turned on. Please set the [Pushing force] and the [TriggerLV] within the specified range.

To ensure that the actuator pushes the workpiece by the inputted [pushing force], it is recommended that the [TriggerLV] is set to the same value as the [pushing force].

2. When pushsing operation, be sure to use in "pushing operation". Also, Never hit at the stroke end.

It causes the breakage and malfunction. The internal stopper can be broken.

3. The positioning force should be set to LESH**：100％ / LESH**A：250％.

If the positioning force is set below LESH**：100％ / LESH**A：250％, it can displace the tack time, which causes an alarm.

4. Actual speed of the product can be changed by load.

When selecting a product, check the catalog for the instructions regarding selection and specifications.

5. Do not apply a load, impact or resistance in addition to a transferred load during return to origin.

Otherwise, the origin can be displaced since it is based on detected motor torque.

6. The table and guide block are made of special stainless.

There can be rust on the product in an environment exposed to water drops.

7. Do not dent, scratch or cause other damage to the body and table mounting surfaces.

It may cause a loss of parallelism in the mounting surfaces, looseness in the guide unit, an increase

in sliding resistance or other problems.

8. Do not dent, scratch or cause other damage to the surface over which the rail and guide will move.

increased sliding resistance and Play can result.

9. When attaching work piece, do not apply strong impact or large moment.

If an external force over the allowable moment is applied, it may cause looseness in the guide unit, an increase in sliding resistance or other problems.

10. Keep the flatness of mounting surace 0.02mm or less.

Insufficient flatness of a work piece or base mounted on the body of the product can cause play at

the guide and increased sliding resistance. Do not place work and do not transform the clamp face by a crowded installation etc.

If the product is set to the same position as a work piece, the following alarm and unstable operation can occur.

a. “Posn failed” alarm

The product cannot reach a pushing start position due to the deviation of work pieces in

width.

b. “Pushing ALM” alarm

The product is pushed back from a pushing start position after starting to push.

15. Please decrease the transportation mass when the outside power hangs in the table. Please note might the increase of the sliding resistance of the table when the piping duct etc. are set up in the actuator, and becoming a defective factor for operation enough.

16. When installing this product using side holders, they should be installed within the range of the dimensions shown below.

Otherwise, the product will be in an unbalanced state, causing looseness.

21. Even with the same product number, the table of some products can be moved by hand

and the table of some products cannot be moved by hand. However, there is no abnormality with these products. (Without lock)

This difference is caused because there is a little variation with the positive efficiency (when the table is moved by the motor) and there is a large variation with the reverse-efficiency (when the table is moved manually) due to the product characteristics. There is hardly any difference among products when they are operated by the motor.
