2. Electric actuators / Common precautions
2.1 Wiring/Cables
Warning
1. Adjustment, installation, inspection, or wiring changes should be conducted after the
power supply to this product has been turned off.
Electrical shock, malfunction, or damage can result.
2. Never disassemble the cable. Use only the specified cables.
3. Never connect or disconnect the cable or connector with the power on.
Caution
1. Wiring should be done correctly.
For each terminal, voltages other than those stipulated in the operation manual should not be
applied.
2. Connect the connector securely.
Check for correct connector wiring and polarity.
3. Handling noise
If the noise is at the same wavelength as the signal lines, it will lead to malfunction. As a
countermeasure, separate the high and low electrical lines, shorten the length of wiring, etc.
4. Do not connect power or high-voltage cables in the same wiring path as the unit.
The product can malfunction due to noise and surge voltage interfer- ence in the signal line from
power and high-voltage cables. Separate the wiring of the controller and its peripheral device
from that of power and high-voltage cables.
5. Be careful that cables are not caught by actuator movement.
6. Operate with cables such that they are not easily moved.
Avoid bending cables at sharp angles where they enter the product.
7. Avoid twisting, folding, rotating, or applying external force to the cable.
Electric shock, wire breakage, contact failure, or a loss of product control may occur.
8. Do not move cables connected to the actuator.
The motor and lock cables are not robotic cables and can be broken when moved. Therefore,
secure the cables and the connectors (part “A” in the figure below) in place during set up.
9. Select a “robotic cable (flexible cable)” when repeated bending of the actuator cable is
required. Also, do not put cables into a flexible moving tube with a radius smaller than the
specified value (50 mm or longer).
Electric shock, wire breakage, contact failure, or a loss of product control may occur if “standard
cables” are used for repeated bend- ing.
10. Confirm wiring insulation.

-11-
Insulation failure (interference with other circuits, poor insulation between terminals, etc.) could
introduce excessive voltage or current to the controller or its peripheral devices, causing damage
to them.
11. The speed and force may change depending on the cable length, load, and mounting
conditions.
Furthermore, if the cable length exceeds 5 m, then it will decrease by up to 10% for every
additional 5 m. (At 15 m: Reduced by up to 20%)
12. When checking the conductivity of the cable, be care- ful not to deform the connector’s
mating hole and terminals.
Inserting a non-compatible connector, tool, cylinder-shaped object, etc., into the connector’s
mating hole can cause the mating hole or terminals to become deformed, which may cause
contact failure or disconnection.
13. Refrain from plugging in and unplugging the connector frequently.
Doing so may result in contact failure or disconnection.
【Transportation】
Caution
1. Do not carry or swing the product by the cable.
2.2 Design/Selection
Warning
1. Be sure to read the operation manual (this manual and the one for the controller: LEC series).
Handling or usage/operation other than that specified in the opera- tion manual may lead to breakage
or operation failure of the product. Any damage attributed to use beyond the specifications is not
covered by the warranty.
2. There is a possibility of dangerous sudden action by the product if the sliding parts of the
machinery are twisted due to external forces, etc.
In such cases, human injury may occur, such as by hands or feet getting caught in the machinery, or
damage to the machinery itself may occur. Design the machinery so as to avoid such dangers.
3. A protective cover is recommended to minimize the risk of personal injury.
If a driven object and the 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 se- cure.
5. Consider a possible loss of power source.
Take measures to prevent injury and equipment damage in the event of a power source failure.
6. Consider emergency stops.
Design so that human injury and/or damage to machinery and equipment will not be caused when
machinery is stopped by a safety device under abnormal conditions, such as a power outage or a
manual emergency stop.
7. Consider the whole system.
Design the system so that human injury or equipment damage will not occur upon the restart of
operation of the whole system.
8. Never disassemble the product or make any modifica- tions, including additional machining.
Doing so may cause human injury and/or an accident. It may also cause the deterioration of the
product’s performance.
9. Do not use the stop signals, the “EMG” of the control- ler and the stop switch on the teaching

-12-
box, as the emergency stop of the system.
The stop signals, “EMG” of the 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 applies to the
relevant safety standards separately.
10. When using the product vertically for applications, it is necessary to install a built-in safety
device.
The table may fall due to the weight of a workpiece. The safety device should not interfere with the
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 a stroke which exceeds 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 may run out.
3. Do not use the product in applications where exces- sive external force or impact force is
applied to it.
The product can be damaged. The components, including the motor, are manufactured to precise
tolerances. Even a slight deformation may cause a malfunction or seizure.
4. During operation (positioning operation or pushing op- eration), it cannot be returned to the
origin position.
5. Refer to the Auto Switches Precautions (pages 15 to 19) if an auto switch is to be built in and
used.
6. Step motor (servo/24 VDC) and servo motor (24 VDC) specifica- tions with the following model
number are not compliant with UL Standards: “Controller/Driver type: Without controller/driver
(Nil).”
Individual actuators are not certified as UL Standards compliant products.
7. When UL Standards compliance is required, the electric actuator and controller/driver should
be used with a UL1310 class 2 power supply.
8. Do not exceed the product specifications even if a work load is supported by external guides.
Although the actuator moment is reduced by external guides, the required trans- port ability (the
relationship between the speed and the work load) is not reduced.
2.3 Mounting
Warning
1. Keep the manual in a safe place for future reference.
The product should be mounted and operated only after thorough- ly reading the operation manual
and understanding its contents.
2. Observe the tightening torque for screws.
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 or damage to the product, which can
lead to human injury or damage to other equipment and machinery.
4. When connecting, make sure the rod axis and the load, and the direction of the movement
match.
Failure to do so may cause complications with the lead screw, such as wear or damage.
5. When an external guide is used, connect the moving parts of the actuator and the load in such

-13-
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, piston rod, etc., by striking or grasping
them with other objects. The com- ponents are manufactured to precise tolerances. Even a slight
deformation may cause a malfunction or seizure.
6. Prevent the seizure of rotating parts (pins, etc.) by ap- plying grease.
7. Do not use the product until you confirm 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. When one side is fixed
When an actuator is operated at a high speed with one end fixed and the other free (basic, flange, or
direct mount types), a bending moment may act on the actuator due to the vibration generated at the
stroke end, which can damage the actuator. In such a case, install a mounting bracket to suppress the
vibration of the actuator body, or reduce the speed so that the actuator does not vibrate. Also, use a
mounting bracket when moving the actuator body or when a long stroke actuator is mounted
horizontally and fixed at one end.
9. Do not apply strong impact or an excessive moment while mounting the product or a
workpiece.
If an external force over the allowable moment is applied, it may cause play in the guide or an increase
in the sliding resistance.
10. Maintenance space
Reserve sufficient space for maintenance.
11. Mounting connectors
Tighten the screws evenly. Tightening torques are as indicated below.
2.4 Handling
Warning
1. Do not touch the motor during operation.
The surface temperature of the motor can increase to approx. 80 C due to operating conditions. The
temperature may also increase due to energiza- tion. As it may cause burns, do not touch the motor
when in operation.
2. If abnormal heating, smoking, fire, etc., occurs in the product, immediately shut off the power
supply.
3. Stop operation at once if there are abnormal noises or vibrations.
For brake connector
Screw size: M2
Tightening torque: 0.2 N m
For power supply connector
Screw size: M2
Tightening torque: 0.2 N m
For encoder connector
Screw size: M2
Tightening torque: 0.1 N m

-14-
Abnormal noises or vibrations may mean that the product is not properly mounted, and if allowed to
continue in this state, damage to the equipment may occur.
4. Never touch the rotating parts of the motor while in operation.
5. Before installing, adjusting, inspecting, or performing maintenance on the product, controller,
and related equip- ment, be sure to shut off the power supply. 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.
6. In the case of an actuator that has a servo motor (24 VDC), the motor phase detection step is
conducted by inputting the servo’s on signal just after the controller power is turned on. The
motor phase detection step moves the table/rod the dis- tance of the one screw-lead as the
maximum.
(The motor rotates in the reverse direction if the table/rod hits an ob- stacle such as the end stop
damper.) Take the motor phase detection step into consideration when installing and operating this
actuator.
Caution
1. Keep the controller and the actuator combined as delivered for use.
The actuator’s parameters are set at the time of shipment. If it is combined with a different set of
parameters, failure can result.
2. Conduct the following inspection before operation.
a) Confirm that the power supply line and each signal line is not damaged.
b) Confirm that the power supply line and each signal line is not loosened.
c) Confirm that the electric actuator/cylinder/controller/driver is not mounted loosely.
d) Confirm that the electric actuator/cylinder/controller/driver is operating correctly.
e) Confirm the function of the emergency stop of the whole system.
3. If several persons are to be working conjointly, determine the pro- cedure, signs, measures
against abnormality, and restarting mea- sures in advance. Then, have someone else,
supervise the work.
4. The product may operate at a speed different from the set speed depending on the load and
resistance.
When selecting a product, check the catalog for instructions regarding selection and specifications.
5. Do not apply a load, impact, or resistance in addition to the transferred load during the return
to origin.
If the product is made to return to origin by pushing force, a displacement of the origin position may
occur.
6. Do not remove the name plate.
7. Operation tests should be done at a low speed. Start operation by predefined speed after
confirming there are no problems.
8. Do not apply forces of impact, collision, or resistance to the moving parts of an actuator in
operation.
Doing so will cause a decrease in product life, damage to the product, etc.
【Grounding】
Warning
1. Be certain to ground the actuator.
2. Dedicated grounding should be used.

If cutting oil, coolant, or oil mist adheres to 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.
Looseness or increased sliding resistance can result.
4. Shade the product from direct sunlight.
5. In locations near heat sources, block them off.
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. Levels of the base oil of grease may decrease due to the exter- nal environment and operating
conditions, causing a decline in lubrication performance and a shortened life of the product.
【Storage】

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 35 to 85% no condensation or freezing).
3. Do not apply vibration or impact to the product during storage.
2.6 Maintenance
Warning
1. Do not disassemble or repair the product.
Fire or electric shock can result. Contact SMC if the disassembly of the product is required for
maintenance.
2. Before modifying or checking the wiring, the voltage should be checked with a tester 5 minutes
after the power supply has been turned off.
Failure to do so may result in electrical shock.
Caution
1. Perform maintenance and inspection according to the procedures indicated in the operation
manual.
Improper handling can cause an injury, damage, or the malfunc- tion of equipment and machinery.
2. Removal of equipment
Before equipment is removed, first confirm that measures are in place to prevent the dropping or
runaway of driven objects, etc. Proceed only after cutting off the electric power. When starting up
again, proceed with caution after confirming that conditions are safe.
3. Be sure to cut the power to the controller and discon- nect the electric actuator cable before
moving the electric actuator slider manually by hand.
If the slider is moved with the electric actuator and controller still connected, the induced voltage of the
motor will go to the control- ler, making it difficult to move the electric actuator smoothly. Moreover,
frequently moving the electric actuator slider may result in controller damage or malfunction due to the
induced voltage.
【Lubrication】
Caution
1. The product has been lubricated for life by the manufac- turer and does not require any further
lubrication.
When lubrication is applied, special grease must be used. Please read the maintenance manual of
each actuator.
2.7 Actuator with Lock
Warning
1. Do not use the lock as a safety brake or as a control that requires a locking force.
The lock used for the product with lock is designed to prevent the dropping of workpieces.
2. For vertical mounting, use the product with lock.
If the product is not equipped with a lock, the product will move and drop the workpiece when the
power is removed. Please ensure that your safe equipment designs include measures to prevent the
falling of workpieces.
3. “Drop prevention” is a safety precaution that prevents a workpiece 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 prod- uct, the lock will lose its holding
force and damage to the sliding parts of the lock or a reduced service life may result. The same
adverse effects may also occur when the lock slips due to a force exceeding the holding force, as this
accelerates the wear of the lock.

-17-
5. Do not apply liquid, oil, or grease to the lock or the area surrounding it.
When liquid, oil, or grease are adhered to the sliding parts of the lock, its holding force will reduce
significantly. Any changes in lock sliding performance and condition may cause a lock release
malfunction.
6. Take measures against drops and check that safety is assured before the mounting,
adjustment, and inspec- tion 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 the SVRE output signal is off), supply 24 VDC to
the [BK RLS] terminal of the power supply connector.
If the product is operated without releasing the lock, the wearing of the lock sliding surface will be
accelerated, causing a reduction in the holding force and the life of the locking mechanism.
8. Do not supply 24 VDC power supply continuously to the [BK RLS (Lock release)] terminal.
Stop supplying 24 VDC 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 when the stop signal (EMG) is received.
9. The actuator may unable to unlock when the sliding part for locking reaches its life due to the
rotation sliding of the shoe during operation. When the lock mechanism reaches its life, please
contact SMC sales office for the replacement parts.
The sliding part for locking may make noise during operation, but this is normal.
Controller (Including Driver) and Peripheral Devices
2.8 Design/Selection
Warning
1. Be sure to apply the specified voltage.
Otherwise, malfunction or breakage may occur. If the applied volt- age is lower than the specified
voltage, it is possible that the load will not be able to be moved due to an internal voltage drop of the
controller. Please check the operating voltage before use.
2. Do not operate the product beyond the specifications.
Otherwise, a fire, malfunction, or actuator damage may result. Please check the specifications before
use. Install an emergency stop circuit.
3. Please install an emergency stop outside of the enclosure so that the system operation can be
stopped immediately and the power supply can be intercepted.
4. In order to prevent any damage caused by the break- down or malfunction of the controller and
its peripher- al devices, a backup system should be established in advance by giving a
multiple-layered structure or a fail-safe design to the equipment, etc.
5. If a danger of human injury is expected due to abnor- mal heat generation, smoking, ignition,
etc., of the controller and its peripheral devices, cut off the power supply of the product and
the system immediately.
Caution
1. Use an actuator with the lock option if the actuator will not be mounted horizontally for use.
Burnout of the internal parts of the controller may occur. If the actuator is not equipped with a lock, it
will move and drop the workpiece when the power and servo are turned OFF.

14. Do not use the product in an environment subject to a temperature cycle.
It will cause failure of the controller or its peripheral devices.
15. Do not use the product in a place where surges are generated.
When there are units that generate a large amount of surge around the product (e.g. solenoid type
lifters, high-frequency in- duction furnaces, motors, etc.), this may cause deterioration or damage to
the product’s internal circuit. Avoid sources of surge generation and crossed lines.
16. Do not install the product in an environment under the effect of vibrations and impacts.
It will cause failure or malfunction.
17. When a surge-generating load, such as a relay or sole- noid valve, is driven directly, use a
product that incor- porates a surge absorption element.
18. The power supplies should be separated between the controller power and the I/O signal power,
and both power supplies must not be of the “inrush-current limited” type.
If the power supply is of the “inrush-current limited” type, a voltage drop may occur during the
acceleration or deceleration of the actuator.

Mount them on different panels, or keep the controller and its peripheral devices away from
such a vibration source.
4. Install the controller and its peripheral devices on a flat surface.
If the mounting surface is distorted or uneven, an unacceptable force may be added to the housing,
etc., causing problems.
5. Take measures to ensure that the operating tempera- tures of the controller and its peripheral
devices are within the range of the specifications. Also, the controller should be installed with
spaces between its sides and the other structures or components.
Failure to do so may cause the malfunction of the controller and its peripheral devices or a fire.
2.11 Power Supply
Caution
1. Use a power supply that has low noise between lines and between the power and ground.
In cases where noise is high, an isolation transformer should be used.
2. To prevent lightning surges, appropriate measures should be taken. Ground the surge
absorber for light- ning separately from the grounding of the controller and its peripheral
devices.
2.12 Grounding
Warning
1. Be sure to carry out grounding in order to ensure the noise tolerance.
2. Dedicated grounding should be used.
Grounding should be to a D-class ground. (Ground resistance of 100 or less)
3. Grounding should be performed near the controller and its peripheral devices to shorten the
grounding distance.
4. In the unlikely event that a malfunction is caused by the ground, please disconnect it.
