6 Selection Procedure Electric Actuator/High Rigidity Slider Type SeriessPage 132 LEJB SeriessPage 137 SeriessPage 533 Ball Screw Drive/ Series Belt Drive/LEJB Series Ball Screw Drive/ Series Clean Room Specification Model Selection Step 1 Check the speed work load. Step 2 Check the cycle time. Step 3 Check the allowable moment. Selection Example Operating conditions Step 3 Check the allowable moment. Refer to Dynamic Allowable Moment graphs (Pages 127 and 128). Mep L3 Work load: 6 [kg] Workpiece mounting condition: Speed: 3 [mm/s] Acceleration/Deceleration: 3 [mm/s 2 ] W Stroke: 3 [mm] Mounting orientation: Horizontal Motor type: Incremental encoder External force: 1 [N] Step 1 Check the speed work load. Select the product by referring to Speed-Work Load Graph (Page 121). Selection example) The 63S3B-3 is temporarily selected based on the graph shown on the right side. The regeneration option may be necessary. Refer to page 121 for Required Conditions for Regeneration Option. Step 2 Check the cycle time. Refer to method 1 for a rough estimate, and method 2 for a more precise value. Method 1: Check the cycle time graph (Page 122) The graph is based on the maximum speed of each size. Method 2: Calculation Cycle time T can be found from the following equation. T = T1 + T2 + T3 + T4 [s] T1 and T3 can be obtained by the following equation. T1 = V/a1 [s] T4 =.5 [s] m T3 = V/a2 [s] 1 The acceleration and deceleration values have upper limits depending on the workpiece mass and the duty ratio. Check that they do not exceed the upper limit, by referring to Work load Acceleration/Deceleration Graph (Guide) (Pages 124 to 126). For the ball screw type, there is an upper limit of the speed depending on the stroke. Check that if it does not exceed the upper limit, by referring to the specifications (Page 133). T2 can be found from the following equation. T2 = L.5 V (T1 + T3) V [s] T4 varies depending on the motor type and load. The value below is recommended. Calculation example) T1 to T4 can be calculated as follows. T1 = V/a1 = 3/3 =.1 [s], T3 = V/a2 = 3/3 =.1 [s] L.5 V (T1 + T3) T2 = V (.1 +.1) = 3 =.9 [s] T4 =.5 [s] Therefore, the cycle time can be obtained as follows. T = T1 + T2 + T3 + T4 = = 1.15 [s] Speed: V [mm/s] L3 [mm] a1 T1 Area where the regeneration option is required.

30 LEJ Series Electric Actuator/ Specific Product Precautions 1 Be sure to read this before handling the products. Refer to back page 5 for Safety Instructions and pages 3 to 8 for Electric Actuator Precautions. Caution Warning Design 1. Do not apply a load in excess of the specification limits. Select a suitable actuator by work load and allowable moment. If the product is used outside of the specification limits, 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. Selection 1. Do not increase the speed in excess of the specification limits. 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 specification limits, 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 (1 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 1. Do not allow the table to hit the end of stroke. When incorrect instructions are inputted, such as using the product outside of the specification limits or operation outside of actual stroke through changes in the controller/driver setting and/or origin position, the table may collide against the stroke end of the actuator. Check these points before use. If the table collides against the stroke end of the actuator, the guide, 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 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. 4. 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. 5. 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. 6. Keep the flatness of mounting surface should be within.1 mm/5 mm. 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), to avoid deflection of the actuator body, use a support plate or support guide. 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. 8. 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.

31 L LEJ Series Electric Actuator/ Specific Product Precautions 2 Be sure to read this before handling the products. Refer to back page 5 for Safety Instructions and pages 3 to 8 for Electric Actuator Precautions. Body fixed Workpiece fixed Handling Caution 1. 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. øa Model Screw Max. tightening øa L size torque [N m] [mm] [mm] LEJ 4 M LEJ 63 M To prevent the workpiece retaining screws from touching the body, use screws that are.5 mm or shorter than the maximum screw-in depth. If long screws are used, they can touch the body and cause a malfunction. 11. Do not operate by fixing the table and moving the actuator body. 12. The belt drive actuator cannot be used vertically for applications. 13. Vibration may occur during operation, this could be caused by the operating conditions. If it occurs, adjust response value of auto tuning of driver to be lower. During the first auto tuning noise may occur, the noise will stop when the tuning is complete. 14. When mounting the actuator using the body mounting reference plane, use a pin. Set the height of the pin to be 5 mm or more because of round chamfering. (Recommended height 6 mm) L Model Screw Max. tightening L (Max. screw-in size torque [N m] depth) [mm] LEJ 4 M6 x LEJ 63 M8 x Warning Maintenance Maintenance frequency Perform maintenance according to the table below.

Items for visual appearance check 1. Loose set screws, Abnormal dirt 2. Check of flaw and cable joint 3. Vibration, Noise Items for internal check 1. Lubricant condition on moving parts. For lubrication, use lithium grease No Loose or mechanical play in fixed parts or fixing screws. Items for belt check Stop operation immediately and replace the belt when belt appear to be below. Further, ensure your operating environment and conditions satisfy the requirements specified for the product. a. Tooth shape canvas is worn out. Canvas fiber becomes fuzzy. Rubber is removed and the fiber becomes whitish. Lines of fibers become unclear. b. Peeling off or wearing of the side of the belt Belt corner becomes round and frayed thread sticks out. c. Belt partially cut Belt is partially cut. Foreign matter caught in teeth other than cut part causes flaw. d. Vertical line of belt teeth Flaw which is made when the belt runs on the flange. e.
