①Adjustment, 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.
②Never disassemble the cable.
③Never connect or disconnect the cable or connector with the power on.
Caution
①Wire the connector securely.
Do not apply any voltage to the terminals other than those specified in the Operation Manual.
②Wire the connector securely.
Check for correct connector wiring and polarity.
③Take appropriate measures against noise.
Noise in a signal line may cause malfunction.
As a countermeasure, high voltage and low voltage cables should be separated, and keep wiring
lengths short, etc.
④Do 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 interference 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.
⑤Take care that actuator movement does not damage cables.
⑥Operate with cables secured.
Avoid bending cables at sharp angles where they enter the electric actuator.
⑦Avoid twisting, folding, rotating, or applying external force to the cable.
Electric shock, wire breakage, contact failure, or a loss of product control may occur.
⑧Fix the Communication cable for setting in place before using.
Communication cable for setting is not robotic type cable and can be damaged when moved.
⑨Select "Robotic type cables" when deflecting power cable and I/O cable repeatedly.
Do not put cables into a flexible moving tube with a radius smaller than the specified
value (minimum 50mm).
Risk of electric shock, wire damage, contact failure and loss of control of the product can occur
if "Standard cables" are used in case of inflecting the cables repeatedly.
⑩Confirm wiring insulation.
Poor insulation (interference with other circuits, poor insulation between terminals and etc.) can
apply excessive voltage or current to the product causing damage.

- 6 -
⑪The 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.(If cable length is 15m: Maximum 20% reduction.)
⑫When checking the conductivity of the cable, be careful not to deform the connector’s
mating hole and terminals.
nserting 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.
⑬Refrain from plugging in and unplugging the connector frequently.
Doing so may result in contact failure or disconnection.

ensure that all parts remain secure.
⑤Consider a possible loss of power source.
Take measures to prevent injury and equipment damage even in the case of a power source failure.
⑥Consider 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.
⑦Consider 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.
⑧Never disassemble or modify (including additional machining) the product.
An injury or failure can result.
It will cause the loss of the product performance.

- 7 -
⑨Do not use the stop signal as the emergency stop of the system.
Stop by shutdown of M24V is for stopping the electric actuator with deceleration.
For the emergency stop of the equipment, design the system with a separate emergency stop
circuit conforming to relevant safety standards.
⑩When using it for vertical application, it is necessary to build in a safety device.
The rod may fall due to the weight of work. The safety device should not interfere with normal
operation of the machine.
⑪Do not exceed the product specifications even if a work load is supported by
external guides.
Although the Electric actuator moment is reduced by external guides, the required trans- port
ability (the relationship between the speed and the work load) is not reduced.
⑫In order to prevent danger and damage due to the breakdown and the malfunction of this
product, which may occur at a certain probability, a backup system should be
established in advance by giving a multiple-layered structure or a fail-safe design to the
equipment, etc.
⑬Avoid designing a system that allows the driving part of an electric actuator to operate
with a spring or other external force.
Caution
①Operate 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.
②When the product repeatedly cycles with partial strokes, operate it at a full stroke at least
once a day or every 1000 strokes.

components.
It may cause a malfunction of the controller and its peripheral devices and a fire.
⑥Do not mount the controller and its peripheral devices near a large electromagnetic
contactor or no-fuse breaker which generates vibration on the same panel. Mount them on
different panels, or keep the controller and its peripheral devices away from such a
vibration source.
⑦Install the electric actuator and its peripheral devices on a flat surface.
If the mounting surface is distorted or uneven, an unacceptable force may be added to the case,
etc., causing problems.
Caution
①Maintenance should be performed according to the procedure indicated in the
Operation Manual.
Incorrect handling can cause an injury, damage or malfunction of equipment and machinery.
②Removal 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
①The product has been lubricated for life at manufacturer, and does not require
lubrication in service.
Contact SMC if lubrication will be applied.
■Precautions for actuator with lock
Warning
①Do 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.
②For 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. If the actuator with lock is not used, preventive measure should be taken
by the design of equipment.
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.
④Do 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
holding force and damage to the sliding part of the lock or reduced lifetime can result. The same
situations will happen when the lock slips due to a force hight than its holding force, as this will
accelerate the wear to the lock.
⑤Do not apply liquid or oil and grease to the lock or its surrounding.
When liquid or oil and grease are adhered to the sliding part of the lock, its holding force will
reduce significantly. Or, lock sliding part performance and condition changes may be cause of
lock release malunction.

- 13 -
⑥Take 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.
⑦When the actuator is operated manually, supply 24VDC to the [LK 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.
⑧Do not supply 24VDC power supply constantly to the [LK RLS(Lock release)] terminal.
Only supply 24 VDC power supply to the [LK RLS(Lock release)] terminal during normal
operation.
If power is supplied to the [LK RLS] terminal continuously, the lock will be released, and
workpieces may be dropped at stop
Electric actuators / Common precautions
■Design/ Selection
Caution
①Do not apply a load in excess of the actuator specification.
A product should be selected based on the maximum work load and allowable moment.
If the product is used outside of the operating specification, eccentric load applied to the
guide will become excessive and have adverse effects such as creating play in the guide,
reduced accuracy and reduced product life.
②Do not exceed the speed limit of the specification.
Select a suitable actuator by the relationship of allowable work load and speed. Noise or
reduction of accuracy may occur, if the actuator is operated in excess of its specification. This
could lead to reduced accuracy and reduced product file.
③Do not use the product in applications where excessive external force or impact force is
applied.
This can lead to premature failure of the product.
④Select a suitable actuator by the relationship of the work load and speed.
If the body is fixed at the end of the actuator (end mounting), excessive load will act on the
actuator body, which may adversely affect the operation and life of the product.

■Handling
Caution
①OUT output signal
1) Positioning Operation
When the actuator moves to within a set range using parameter 【OUT output signal with】, the
output signal, INP, will be turned on.
Set to [0.50] or higher. It may cause malfunction.
②When pushing operation, be sure to use in “pushing operation”.
Do not hit the work piece in positioning operation or in the range of positioning operation.
It may lead to a malfunction.
③Keep the specifications driving speed range for pushing operation.
This may lead to damage and malfunction.
④Check the specification for the minimum speed of each actuator. Operation outside the
specifications may cause malfunctions such as knocking.
⑤Actual speed of the product can be changed by load.
When selecting a product, check the catalog for the instructions regarding selection and
specifications.
⑥Do 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 the detected motor torque.
⑦In pushing operation, set the product to a position of at least 2mm away from a work
piece. (This position is referred to as a pushing start position.)
If the product is set to the same position as a work piece, the following alarm and unstable
operation can occur.
a. ”Posn failde” 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.
⑧Do not scratch or gouge the sliding parts of the piston rod, by striking or grasping them
with other objects.
Piston rod is manufactured to precise tolerances, so that even a slight deformation may cause
malfunction.
⑨Please connect the product such that the impact and load may not be added to the rod
from the side when an external guide is used.
Use a freely moving connector (such as a floating joint).
⑩Please do not operate body itself by the piston rod fixing.
An excessive load joins the piston rod, and it causes defective operation and the longevity
decrease.

⑪When an actuator is operated with one end fixed and the other free (ends tapped or
flange 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 mounting
bracket to suppress the vibration of the actuator body or reduce the speed so that
the actuator does not vibrate at the stroke end.
Also, use a mounting bracket when moving the actuator body or when a long stroke actuator is
mounted horizontally and fixed at one end.
⑫Avoid using the electric actuator in such a way that rotational torque would be applied to
the piston rod.
If rotational torque is applied, the non-rotating guide will become deformed, thus affecting the non-
rotating accuracy. Refer to the table below for the approximate values of the allowable range of
rotational torque.

To screw a bracket or a nut onto the threaded portion at the tip of the piston rod, make sure to
retract the piston rod entirely, and place a wrench over the flat portion of the rod that protrudes.
Tighten it by giving consideration to prevent the tightening torque from being applied to the non-
rotating guide.
⑬Operate within the following ranges of the duty ratio when pushing operation.
The duty ratio is a ratio at the time that can keep being pushed.

⑭When mounting the actuator, leave a gap of 40mm or more to allow for bending of the actuator
cable.

■Mounting
Caution
①Design the installation so that the temperature surrounding the actuator is 40oC or less.
②Keep the flatness of the mounting surface within the following ranges when mounting
the actuator body and work piece.
Insufficient flatness of the work piece or the surface onto which the actuator body is to be mounted
can cause increased sliding resistance, noise, life time reduction.
③Fix 'Socket' square width across flats in the piston rod point with the spanner etc. ,
prevent the piston rod from rotating, and tighten the screw tightening when work piece
or tool, etc. are installed properly by the torque value within the range of the limitation.
It causes the abnormal reaction of an auto switch, the space of an internal guide, and an
increase of the sliding resistance, etc.
④When mounting the product, use screws of adequate length and tighten them to the correct
torque.
Tightening the screws with a higher torque than the maximum may cause malfunction, whilst
tightening with a lower torque can cause the displacement of the mounting position or in
extreme conditions detaching of the work piece.
