32 Series LEJ Electric Actuator/ Specific Product Precautions 1 Be sure to read before handling. Refer to back cover for Safety Instructions and the Operation Manual for Electric Actuator Precautions. Please download it via our website, Caution Warning Design 1. Do not apply a load in excess of the operating limit. A product should be selected based on the maximum load and allowable moment. If the product is used outside of the operating limit, eccentric load applied to the guide will become excessive and have adverse effects such as creating play at the guide, degraded accuracy and shortened product life. 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 faulty operation or seizure. Selection 1. Do not exceed the speed limit of the actuator specification. Select a suitable actuator by the relationship of the allowable work load and speed, and the allowable speed of each stroke. Noise or reduction of accuracy may occur if the actuator is operated in excess of its specification and could lead to reduced accuracy and reduced product file. 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 1 strokes. 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. It can cause damage to the actuator. Handle the actuator with care, especially when it is used in the vertical direction. 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 a transferred load during returning to the original position. 4. Do not dent, scratch or cause other damage to the body and table mounting surfaces. It may cause a loss of parallelism in the mounting surfaces, looseness in the guide unit, an increase in sliding resistance or other problems. 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 looseness in the guide unit, an increase in sliding resistance or other problems.. Keep the flatness of mounting surface.1 mm or less. Insufficient flatness of a workpiece or base mounted on the body of the product can cause play at the guide and increased 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. Particularly during the transportation. 21

33 Series LEJ Electric Actuator/ Specific Product Precautions 2 Be sure to read before handling. Refer to back cover for Safety Instructions and the Operation Manual for Electric Actuator Precautions. Please download it via our website, Model Selection 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 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. Body fixed Workpiece fixed L Model LEJ4 LEJ3 Model LEJ4 LEJ3 øa Bolt M5 M Bolt M x 1 M8 x 1.25 øa (mm) Max. tightening torque (N m) L (mm) L (Max. screw-in depth) (mm) 1 12 To prevent the workpiece fixing bolts from touching the body, use bolts that are.5 mm or shorter than the maximum screw-in depth. If long bolts are used, they can touch the body and cause malfunction, etc. 11. Do not operate by fixing the table and moving the actuator body. 12. The belt drive actuator cannot be used for vertically 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 chamfering. (Recommended height mm) L Warning Maintenance Maintenance frequency Perform maintenance according to the table below. Frequency Appearance check Internal check Belt check Inspection before daily operation Inspection every months/1 km/ 5 million cycles Select whichever comes sooner. 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. Rubber back of the belt is softened and sticky. f. Crack on the back of the belt AC Servo Motor LEJB LEJS Specific Product Precautions LECS Body mounting reference plane 22
