LEF Series / Slider type Safety Instructions Caution The product is provided for use in manufacturing industries. The product herein described is basically provided for peaceful use in manufacturing industries. If considering using the product in other industries, consult SMC beforehand and exchange specifications or a contract if necessary.
1.2 Startup When switching the power on for the first time, follow the startup procedure below. The setting of the filter parameter might become necessary for LEFB25S, and confirm paragraph 7.6, please. Refer to the “Driver operation manual” for wiring method and detailed procedure. Confirm that the cables to the driver and the actuator are - - - Wiring check...
3)Please set load moment of inertia ratio to about 50 times after it sets it to auto-tuning Mode 2 when you drive in low speed in LECSB, LECSC, and LECSS (state that the auto-tuning mode doesn't operate). - 7 -...

5. Wiring of cables / Common precautions Warning Adjusting, mounting or wiring change should never be done before shutting off the power supply to the product. Electrical shock, malfunction and damaged can result. Never disassemble the cable. Use only specified cables. Never connect or disconnect the cable or connector with power on.
6. Electric actuators / Common precautions 6.1 Design and selection Warning 1. Be sure to read the Operation Manual (this manual and the one for the driver: LEC series). Handling or usage/operation other than that specified in the Operation Manual may lead to breakage and operation failure of the product.
6.2 Mounting Warning 1. Install and operate the product only after reading the Operation Manual carefully and under standing its contents. Keep the manual in a safe place future reference. 2. Observe the tightening torque for screws. Tighten the screws to the recommended torque for mounting the product. 3.
6.3 Handling Warning 1. If abnormal heating, smoking or fire, etc., occurs in the product, immediately shut off the power supply. 2. Immediately stop operation if abnormal operation noise or vibration occurs. If abnormal operation noise or vibration occurs, the product may have been mounted incorrectly. Unless operation of the product is stopped for inspection, the product can be seriously damaged.
6.4 Operating environment Warning 1. Avoid use in the following environments. a. Locations where a large amount of dusts and cutting chips are airborne. b. Locations where the ambient temperature is outside the range of the temperature specification (refer to specifications). c.
6.5 Maintenance Warning 1. Do not disassemble or repair the product. Fire or electric shock can result. 2. Before modifying or checking the wiring, the voltage should be checked with a tester 5 minutes after the power supply is turned off. Electrical shock can result.
7. Electric actuators / Slider type Common precautions 7.1 Design and selection Warning Do not apply a load in excess of the actuator specification. A product should be selected based on the maximum work load and allowable moment. If the product is used outside of the operating specification, eccentric load applied to the guide will become excessive and have adverse effects such as creating play in the guide, reduced accuracy and reduced product life.
7.3 Mounting Caution 1. Keep the flatness of mounting surace to within 0.1mm or less. Insufficient flatness of the work piece or the surface onto which the actuator body is to be mounted can cause play in the guide and increased sliding resistance. 2.
7.4 Precaution on maintenance Warning 1. Turn off the power supply before maintenance and replacement of the product.. 2. Put on protective goggles when applying grease. [Maintenance frequency] Perform maintenance according to the table below. Contact SMC if any abnormality is found. Appearance Internal Belt...
7.5 How to detach and attach the dust seal band For the internal-check as the maintenance, the method of detaching and attaching the dust seal band is shown as the following . <Dis-assembly> Loosen the fixing bolts of end side of the “Band holder”. (The picture shows LEFB, but LEFS is same instruction as LEFB.) Pay attention to not cut hand on the edges of the "Dust seal band".
7.6 Replacement of belt 1. After Bolt is removed, "Pulley plate" is removed. Bolts 2. "Motor cover" and "Grommet" are removed. (Only "With motor cover") Bolts 3. After "Belt" is installed, and the bearing support is obtained, the root of "Motor" is pulled in a string or a long banding band.
8.Troubleshooting 8.1 Alarms and Warning When a fault occurs during the operation, the corresponding alarm or warning is displayed. If any alarm or warning has occurred, refer to 「Driver Operation Manual」and take the appropriate action. After removing the cause of the alarm, the alarm can be deactivated in any of the methods marked ○ in the alarm deactivation column.
