3.4 Parameter setting Initial setting for the basic parameters Refer to the controller’s (LEC series) operation manual for detail. As the “basic parameter” is unique data of each actuator, if an actuator other than the “electric actuator / slider type” is used, refer to the operation manual of each actuator and the controller’s (LEC series) operation manual for the basic parameter.
Page 27
Initial setting for the ORIG parameters Refer to the controller’s (LEC series) operation manual for detail. As the “ORIG parameter” is unique data of each actuator, if an actuator other than the “electric actuator / slider type” is used, refer to the operation manual of each actuator and the controller’s (LEC series) operation manual for the “ORIG parameters”.
Page 28
<Origin offset> The origin offset means the value of the origin. (“Origin offset”=The display value of origin) When the parameter “Origin offset” is changed, the value of “Stroke(+)”, “Stroke(-)” of basic parameter should be checked again. When the parameter “Origin offset” is changed, the display value of origin is changed. The step data should be checked again.
4. Wiring of cables / Common precautions Warning Adjusting, mounting or wiring change should never be done before disconnecting the power supply to the product. Electrical shock, malfunction and damage can result. Do not disassemble the cables. Use only specified cables. Do not connect or disconnect the wires, cables and connectors when the power is turned on.
5. Electric actuators / Common precautions 5.1 Design and selection Warning 1. Be sure to read the operation manual (this manual and the one for the controller: LEC series). Handling or usage/operation other than that specified in the Operation Manual may lead to breakage and operation failure of the product.
It cannot be done during positioning operation, pushing operation and pushing. Refer to a common auto switch /matter (Best Pneumatics No 2) when an auto switch is built in and used. 5.2 Mounting Warning 1. Install and operate the product only after reading the Operation Manual carefully and understanding its contents.
a) Damage to electric driving line and signal line. b) Looseness of the connector to each power line and signal line. c) Looseness of the actuator /cylinder and controller /driver mounting d) Abnormal operation e) Emergency stop of the total system When more than one person is performing work, decide on the procedures, signals, measures and resolution for abnormal conditions before beginning the work.
harmful gas or liquid. 2. Store in an area that is shaded from direct sunlight and has a temperature and humidity within the specified range (-10°C to 60°C and 35 to 85% No condensation or freezing). 3. Do not apply vibration and impact to the product during storage. 5.5 Maintenance Warning Do not disassemble or repair the product.
6. Electric actuators / Slider type Common precautions 6.1 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.
6.3 Mounting Caution 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. When mounting the workpiece or other device to the actuator tighten the fixing screws with adequate torque within the specified torque range.

[Items for visual appearance check] 1. Loose screws. Abnormal dirt. 2. Check of flaws/faults and cable connections. 3. Vibration, noise. [Items for internal check] 1. Lubricant condition on moving parts. 2. Loose or mechanical play in fixed parts or fixing screws. [Items for belt check] Check the belt regularly as shown in “maintenance frequency”.
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> 1. 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".
