Mounting Warning 1. Keep the manual in a safe place future reference. The product should be mounted and operated after thoroughly reading the operation manual and understanding its contents. 2. Observe the tightening torque for screws. Tighten the screws to the recommended torque for mounting the product. 3. Do not make any alterations to this product. Alterations made to this product may lead to a loss of durability and damage to the product, which can lead to human injury and damage to other equipment and machinery. 4. Connect the rod axis and the load and the direction of the movement being sure to match it. It causes to cause the complication in the lead screw, to be worn out, and to damage it when not matching. 5. When an external guide is used, connect the moving parts of the actuator and the load in such a way that there is no interference at any point within the stroke. Do not scratch or dent the sliding parts of the product tube or piston rod etc., by striking or grasping them with other objects. The components are manufactured to precise tolerances. So that even a slight deformation may cause a malfunction or seizure. Warning 6. Prevent the seizure of rotating parts (pins, etc.) by applying grease. 7. Do not use the product until you verify that the equipment can operate properly. After mounting or repair, connect the power supply to the product and perform appropriate functional inspections to check it is mounted properly. 8. When one side is fixed When an actuator is operated at high speed with one end fixed and the other free (basic, flange or direct mount types), 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. 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. 10. Maintenance space Reserve sufficient space for maintenance. Mounting Warning Handling Design/Selection Warning 1. Do not touch the motor in operation. The surface temperature of the motor can increase to approx. 80°C due to operating conditions. This temperature increase may also be caused by energizing alone. As it may cause burns, do not touch the motor when in operation. 2. If abnormal heating, smoking or fire, etc., occurs in the product, immediately shut off the power supply. 3. Stop operation at once if there are abnormal noises or vibrations. Abnormal noises or vibrations may mean that the product is not properly mounted, and if allowed to continue in this state, damage to the equipment may occur. 4. Never touch the rotating part of the motor while in operation. 5. When installing, adjusting, inspecting or performing maintenance on the product, controller and related equipment, be sure to shut off the power supply to them. Then, lock it so that no one other than the person working can turn the power on, or implement measures such as a safety plug. 6. In the case of the actuator that has a servo motor (24 VDC), the motor phase detection step is done by inputting the servo on signal just after the controller power is turned on. The motor phase detection step moves the table/rod for the distance of the one screw-lead as the maximum. (The motor rotates in the reverse direction if the table hits an obstacle such as the end stop damper.) Take the motor phase detection step into consideration for the installation and operation of this actuator. Caution 1. Keep the controller and the actuator combined as delivered for use. The actuator is set in parameters for shipment. If it is combined with a different parameter, failure can result. Caution 1. Operate within the limits of the maximum usable stoke. The product will be damaged if it is used with the stroke which is over the maximum stroke. Refer to the specifications of the product. 2. When the product repeatedly cycles with partial strokes, operate it at a full stroke at least once a day or every 1000 strokes. Otherwise, lubrication can run out. 3. 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. 4. During operation (positioning operation or pushing operation), it cannot be returned to the origin position. 5. Refer to Auto Switches Precautions (Best Pneumatics No. 2) when an auto switch is built in and used. 6. When conformity to UL is required, the electric actuator and controller/driver should be used with a UL1310 Class 2 power supply. Electric Actuators Precautions 2 Be sure to read before handling. 9. Do not use the stop signal, “EMG” of the controller and stop switch on the teaching box as the emergency stop of system. The stop signal, “EMG” of controller and the stop switch on the teaching box are for decelerating and stopping the actuator. Design the system with an emergency stop circuit which is applied relevant safety standard separately. 10. When using it vertically for applications, it is necessary to build in a safety device. The table may fall due to the weight of workpiece. The safety device should not interfere with normal operation of the machine. 65 B
