Page 3: Safety Instructions
Electric Actuator/Rod Type compatible with manifold controller Safety Instructions These safety instructions are intended to prevent hazardous situations and/or equipment damage. These instructions indicate the level of potential hazard with the labels of “Caution,” “Warning” or “Danger.” They are all important notes for safety and must be followed in addition to International Standards (ISO/IEC) *1), and other safety regulations.
Page 4: Safety Precautions
Electric Actuator/Rod Type compatible with manifold controller Safety Precautions Caution We develop, design, and manufacture our products to be used for automatic control equipment, and provide them for peaceful use in manufacturing industries. Use in non-manufacturing business is not covered. Products we manufacture and sell cannot be used for the purpose of transactions or certification specified in the Measurement Act.
Page 5: Precautions For Product Specific
Precautions for product specific Precautions for wiring and cable Warning ① Installation, adjustment, inspection, or wiring changes should be conducted with the power supply to this product turned OFF. Electrical shock, malfunction, or damage can result. ② Never disassemble the cable. ③...
Page 6: Electric Actuators / Common Precautions
⑨ When the actuator cable is to be bent repeatedly, do not route it in a movable wiring duct smaller than the minimum specified radius (For cable lengths of 10 m or less: bend radius = 56 mm minimum; For cable lengths of 15 m or more: bend radius = 77 mm minimum).
Page 7 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 proximity, personal injury may occur. Design the system to avoid contact with the human body. ④...
Page 8 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...
Page 9 ⑨ When mounting the actuator or attaching the work piece, do not apply strong impact or large moment. If an external force above the allowable moment is applied, it may cause looseness in the guide unit, an increase in sliding resistance or other problems. ⑩...
Page 10 ⑥ The inside of the electric actuator and its connector should not be touched. It may cause an electric shock or damage to the controller. ⑦ Do not perform the operation or setting of the product with wet hands. Doing so may cause an electric shock. ⑧...
Page 11 ⑳ In the case of an actuator that has a servo motor (24 VDC), the motor phase detection step is conducted by inputting the servo ON signal just after the controller power is turned on. The motor phase detection step moves the table/rod by a distance of one screw-lead maximum.
Page 12: Power Supply
⑤ Avoid common grounding points shared with other devices. ■ 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...
Page 13 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.
Page 14 Caution ① Maintenance 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. 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.
Page 15: Electric Actuators / Rod Type - Common Precautions
⑦ If the mover of electric actuator with lock is intentionally moved by external force (e.g. spring, human power, etc.), supply 24 V DC of the lock release power supply to the LKRLS1 and LKRLS2 terminals of the power supply blocking plug after the controller input power supply primary side is shut off.
Page 16 ■ Handling Caution ① INP Output Signal 1) Positioning operation The INP output signal turns ON when the position is within the range set by the parameter 【Positioning Width】 relative to the target position. Default value: Set at 【0.50】 or more. This may cause a malfunction. ②...
Page 17 ⑫ Avoid using the electric actuator in such a way that rotational torque would be applied to the piston rod.[LE2Y series] 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.
Page 18 ■ Mounting Caution ① Design the installation so that the temperature surrounding the actuator is 40oC or less. ② Keep 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.

Page 20 ■ Maintenance Caution ① Cut the power supply during maintenance and replacement of the product. 【 Maintenance frequency 】 Preform maintenance according to the table below. Please contact SMC if there are any problems Appearance Frequency Belt check check 〇 Inspect daily before operating Inspection every six months / 〇...
Page 21 【Grease application】 If grease lubrication performance is reduced due to operating environment or operating conditions, please re-apply grease. 1. Grease application to the piston rod Fully extend the piston rod by performing a JOG operation and apply grease to the base of the piston rod.
Page 22 3. Grease application to the inside of the body and to the ball screw （For strokes of 200 mm or more） Move the piston rod to the extended end by JOG operation, etc., and remove the oil filler cap. Insert the tip of the spray grease into the grease inlet and spray the inside of the body with grease. After applying grease, attach the cap.
Page 23 【Items for belt check】 Check the belt regularly as shown in “maintenance frequency”. Stop operation immediately and contact SMC when the belt appears to be like the photographs shown below. a. Tooth shape canvas is worn out Canvas fiber becomes fuzzy. Rubber is removed and the fiber becomes white in color. Lines of fibers become unclear.
Page 24 ■ Replacement of belt ① After screws are removed, the "Pulley plate" and “Motor cover” are removed. Screws Screws ② The motor fixing screws are loosened (To extent in which the slide can be done), the "Bearing support" is removed, and the "Belt" is removed. Screws ③...
Page 25 Specific precautions for Battery-less absolute encoder Warning ① Do not use in an environment where strong magnetic fields are present. A magnetic sensor is used in the encoder. Therefore, if the actuator motor is used in a strong magnetic field environment, malfunction or failure may occur. The major failure is described below.
Page 26 （Example 3） Multiple actuators can be placed close to each other as shown in the figure below, as long as magnets are not close around the motor section. Caution ① Supply power when the actuator is stationary. The electric actuator acquires the absolute position data from the absolute encoder when power is applied.
