Step 3 Check the allowable moment. Selection Example Operating conditions Workpiece mass: [kg] Workpiece mounting condition: Speed: 3 [mm/s] W Acceleration/Deceleration: 3 [mm/s 2 ] Stroke: 2 Mounting position: Horizontal upward Incremental encoder Settling time Work load: W [kg] Lead : LEFSB Lead 2: LEFSA Step Step 2 Step 3 Check the work load speed. <Speed Work Load Graph> Select a model based on the workpiece mass and speed which are within the range of the actuator body specifications with reference to the Speed Work Load Graph (Guide) on page. Selection example) The LEFSSB-2 is temporarily selected based on the graph shown on the right side. L Refer to the selection method of motor manufacturers for regeneration resistance. Check the cycle time. Calculate the cycle time using the following calculation method. Cycle time: T can be found from the following equation. T = T + T2 + T3 + T [s] T: Acceleration time and T3: Deceleration time can be obtained by the following equation. T = V/a [s] T3 = V/a2 [s] T2: Constant speed time can be found from the following equation. L. V (T + T3) T2 = [s] V T: Settling time varies depending on the T = T + T2 + T3 + T conditions such as motor types, load and = in positioning of the step data. Therefore, calculate the settling time with reference =.2 [s] to the following value. T =. [s] The conditions for the settling time vary depending on the motor or driver to be used. Check the guide moment. Mep m Calculation example) T to T can be calculated as follows. T = V/a = 3/3 =. [s], T3 = V/a2 = 3/3 =. [s] L. V (T + T3) T2 = V 2. 3 (. +.) = 3 =.7 [s] T =.

32 Series LEF Electric Actuator Specific Product Precautions Be sure to read this before handling. Refer to the back cover for Safety Instructions. For Electric Actuator Precautions, refer to Handling Precautions for SMC Products and the Operation Manual on SMC website, Caution Design. Do not apply a load in excess of the operating limit. Select a suitable actuator by work load and allowable moment. If the product is used outside of the operating limit, the eccentric load applied to the guide will be excessive and have adverse effects such as creating play on the guide, degrading accuracy and shortening the life of the product. 2. Do not use the product in applications where excessive external force or impact force is applied to it. This can cause a failure. Warning Selection. Do not increase the speed in excess of the operating limit. Select a suitable actuator by the relationship of the allowable work load and speed, and the allowable speed of each stroke. If the product is used outside of the operating limit, it will have adverse effects such as creating noise, degrading accuracy and shortening the life of the product. 2. Do not use the product in applications where excessive external force or impact force is applied to it. This can cause a failure. 3. When the product repeatedly cycles with partial strokes (see the table below), operate it at a full stroke at least once every dozens of cycles. Otherwise, lubrication can run out. LEF2 LEF32 LEF Partial stroke mm or less 7 mm or less mm or less. When external force is applied to the table, it is necessary to add external force to the work load as the total carried load for the sizing. When a cable duct or flexible moving tube is attached to the actuator, the sliding resistance of the table increases and may lead to operational failure of the product. Caution Handling. Do not allow the table to hit the end of stroke. When the driver parameters, origin or programs are set incorrectly, the table may collide against the stroke end of the actuator during operation. Check these points before use. If the table collides against the stroke end of the actuator, the guide, ball screw, belt or internal stopper can be broken. This may lead to abnormal operation. Handle the actuator with care when it is used in the vertical direction as the workpiece will fall freely from its own weight. 2. The actual speed of this actuator is affected by the work load and stroke. Check the specifications with reference to the model selection section of the catalog. 3. Do not apply a load, impact or resistance in addition to the transferred load during return to origin.. Do not dent, scratch or cause other damage to the body and table mounting surfaces. This may cause unevenness in the mounting surface, play in the guide or an increase in the sliding resistance.. Do not apply strong impact or an excessive moment while mounting 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.. Keep the flatness of mounting surface. mm or less. Unevenness of a workpiece or base mounted on the body of the product may cause play in the guide and an increase in the sliding resistance. 7. Do not hit the table with the workpiece in the positioning operation and positioning range. 3

51 Caution Design. Do not apply a load in excess of the operating limit. Select a suitable actuator by work load and allowable moment. If the product is used outside of the operating limit, the eccentric load applied to the guide will be excessive and have adverse effects such as creating play on the guide, degrading accuracy and shortening the life of the product. 2. Do not use the product in applications where excessive external force or impact force is applied to it. The product can be damaged. The components including the motor are manufactured to precise tolerances. So that even a slight deformation may cause a malfunction or seizure. Warning Series LEJS Electric Actuator Specific Product Precautions Be sure to read this before handling. Refer to the back cover for Safety Instructions. For Electric Actuator Precautions, refer to Handling Precautions for SMC Products and the Operation Manual on SMC website, Selection. Do not increase the speed in excess of the operating limit. Select a suitable actuator by the relationship of the allowable work load and speed, and the allowable speed of each stroke. If the product is used outside of the operating limit, it will have adverse effects such as creating noise, degrading accuracy and shortening the life of the product. 2. When the product repeatedly cycles with partial strokes ( mm or less), lubrication can run out. Operate it at a full stroke at least once a day or every a thousand cycles. 3. When external force is applied to the table, it is necessary to add external force to the work load as the total carried load for the sizing. When a cable duct or flexible moving tube is attached to the actuator, the sliding resistance of the table increases and may lead to operational failure of the product. Caution Handling. Do not allow the table to hit the end of stroke. When the driver parameters, origin or programs are set incorrectly, the table may collide against the stroke end of the actuator during operation. Check these points before use. If the table collides against the stroke end of the actuator, the guide, ball screw, belt or internal stopper can be broken. This may lead to abnormal operation. Handle the actuator with care when it is used in the vertical direction as the workpiece will fall freely from its own weight. 2. The actual speed of this actuator is affected by the work load and stroke. Check the specifications with reference to the model selection section of the catalog. 3. Do not apply a load, impact or resistance in addition to the transferred load during return to origin.. Do not dent, scratch or cause other damage to the body and table mounting surfaces. This may cause unevenness in the mounting surface, play in the guide or an increase in the sliding resistance.. 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.. Keep the flatness of mounting surface. mm or less. Unevenness of a workpiece or base mounted on the body of the product may cause play in the guide and an increase in the sliding resistance. In the case of overhang mounting (including cantilever), use a support plate or support guide to avoid deflection of the actuator body. 7. When mounting the actuator, use all mounting holes. If all mounting holes are not used, it influences the specifications, e.g., the amount of displacement of the table increases.. Do not hit the table with the workpiece in the positioning operation and positioning range. 9. Do not apply external force to the dust seal band. Particularly during the transportation LEYG LEY LEJS LEFB LEFS Selection Motor Mounting

52 Series LEJS Electric Actuator Specific Product Precautions 2 Be sure to read this before handling. Refer to the back cover for Safety Instructions. For Electric Actuator Precautions, refer to Handling Precautions for SMC Products and the Operation Manual on SMC website, Caution Handling. When mounting the product, use screws with adequate length and tighten them with adequate torque. Tightening the screws with a higher torque than recommended may cause a malfunction, whilst the tightening with a lower torque can cause the displacement of the mounting position or in extreme conditions the actuator could become detached from its mounting position. Warning Maintenance Maintenance frequency Perform maintenance according to the table below.

84 Series LEY/LEYG Electric Actuators Specific Product Precautions Be sure to read this before handling. Refer to the back cover for Safety Instructions. For Electric Actuator Precautions, refer to Handling Precautions for SMC Products and the Operation Manual on SMC website, Warning Design/Selection. Do not apply a load in excess of the operating limit. Select a suitable actuator by work load and allowable lateral load on the rod end. If the product is used outside of the operating limit, the eccentric load applied to the piston rod will be excessive and have adverse effects such as creating play on the sliding parts of the piston rod, degrading accuracy and shortening the life of the product. 2. Do not use the product in applications where excessive external force or impact force is applied to it. This can cause a failure. 3. When used as a stopper, select the LEYG series Sliding bearing for a stroke of 3 mm or less.. When used as a stopper, fix the main body with a guide attachment ( Top mounting or Bottom mounting ). If the end of the actuator is used to fix the main body (end mounting), the excessive load acts on the actuator, which adversely affects the operation and life of the product. Caution Handling. When using the pushing operation, be sure to set to force/speed control, and use within the specified pushing speed range for each series. Do not allow the piston rod to hit the workpiece and end of the stroke in the position control. The lead screw, bearing and internal stopper may be damaged and lead to malfunction. 2. For pushing operation, the maximum value of the reference motor torque should be 9% or less of the rated torque. For the LEY3, % or less. It may lead to damage and malfunction. 3. The maximum speed of this actuator is affected by the product stroke. Check the model selection section of the catalog.. Do not apply a load, impact or resistance in addition to the transferred load during return to origin. Additional force will cause the displacement of the origin position.. Do not scratch or dent the sliding parts of the piston rod, by striking or attaching objects. The piston rod and guide rod are manufactured to precise tolerances, even a slight deformation may cause a malfunction.. When an external guide is used, connect it in such a way that no impact or load is applied to it. Use a freely moving connector (such as a floating joint). 7. Do not operate by fixing the piston rod and moving the actuator body. Excessive load will be applied to the piston rod, leading to damage to the actuator and reduced the life of the product. 3 Caution Handling. When an actuator is operated with one end fixed and the other free (ends tapped (standard), 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. 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. Avoid using the electric actuator in such a way that rotational torque would be applied to the piston rod. This may cause deformation of the non-rotating guide, abnormal responses of the auto switch, play in the internal guide or an increase in the sliding resistance. Refer to the table below for the approximate values of the allowable range of rotational torque. Allowable rotational torque lbf ft [N m] or less LEY2. [.] LEY32.3 [.] LEY3 2. [2.] When screwing in a bracket or nut to the piston rod end, hold the flats of the end of the socket with a wrench (the piston rod should be fully retracted). Do not apply tightening torque to the non-rotating mechanism.. When using auto switch with the guide rod type LEYG series, the following limits will be in effect. Please select the product while paying attention to this. Insert the auto switch from the front side with rod (plate) sticking out. The auto switches with perpendicular electrical entry cannot be used. For the parts hidden behind the guide attachment (Rod stick out side), the auto switch cannot be fixed. Please consult with SMC when using auto switch on the rod stick out side.
