The actual workload will depend on the type of external guide.
Note 2) The force setting range (set values for the driver) for the force control with the torque control mode. Set it with reference to “Force
Conversion Graph” of the catalog
The driver applicable to the pushing operation is "LECSB-T", "LECSS", and "LECSS-T. "
The LECSB-T is only applicable when the control method is positioning. The point table is used to set the pushing operation
settings.
To set the pushing operation settings, an additional dedicated file (pushing operation extension file) must be downloaded
separately to be used with the setup software (MR Configurator2™: LEC-MRC2□).
Please download this dedicated file from the SMC website: https://www.smcworld.com/
When selecting the LECSS or LECSS-T, combine it with a master station (such as the Simple Motion module manufactured by
Mitsubishi Electric Corporation) which has a pushing operation function.
Note 3) The allowable speed changes by the stroke.
Note 4) Allowable impact speed when "impact work" in torque control mode, etc.
Note 5) Impact resistance: No malfunction occurred when the actuator was tested with a drop tester in both an axial direction and 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 6) Only when the motor option, "with lock", is selected.
Note 7) For an actuator with lock, add the power consumption for the lock.

Note 1) The maximum value of the horizontal workload. (An external guide is necessary[Coefficient of friction:0.1 or less]).
The actual workload will depend on the type of external guide.
Note 2) The force setting range (set values for the driver) for the force control with the torque control mode. Set it with reference to “Force
Conversion Graph” of the catalog
The driver applicable to the pushing operation is "LECSB-T", "LECSS", and "LECSS-T. "
The LECSB-T is only applicable when the control method is positioning. The point table is used to set the pushing operation settings.
To set the pushing operation settings, an additional dedicated file (pushing operation extension file) must be downloaded separately
to be used with the setup software (MR Configurator2™: LEC-MRC2□).
Please download this dedicated file from the SMC website: https://www.smcworld.com/
When selecting the LECSS or LECSS-T, combine it with a master station (such as the Simple Motion module manufactured by
Mitsubishi Electric Corporation) which has a pushing operation function.
Note 3) Allowable impact speed when "impact work" in torque control mode, etc.
Note 4) Impact resistance: No malfunction occurred when the actuator was tested with a drop tester in both an axial direction and
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) Only when the motor option, "with lock", is selected.
Note 6) For an actuator with lock, add the power consumption for the lock.

4. Product Outline
4.1 System construction
Refer to the “Driver operation manual / FUNCTIONSAND CONFIGURATION” for system construction.
5. Electric actuators / Common precautions
5.1 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.
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.
5.2 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.

-19-
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
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.
