1 SMC solutions electric actuators Problems programming your electric actuator? Easy setting electric actuators delivering outstanding speed, force and positioning control

2 Electric Actuators Speed, Force and Positioning Control SPEED, FORCE and POSITIONING CONTROL SPEED - a rate (usually rapid) at which something happens FORCE - the influence that produces a change in a physical quantity (force = mass x acceleration) POSITIONING CONTROL - a type of control system designed for moving objects or machines to a known position or multiple positions (often linked to the noun precision) Three performance features which are often used when describing the benefits of electric actuation. Actuator - typically a mechanical device that takes energy, usually transported by air, electric current, or liquid, and converts that into some kind of motion. (Information source - Wikipedia) So are electric actuators better than air operated pneumatic options? The simple answer it completely depends on the application! When selecting either pneumatic or electric actuators for your automation control needs, the application and its specific location will ultimately help determine your selection. Both technologies have a number of advantages and disadvantages. In summary Pneumatic Actuators: are relatively inexpensive to purchase offer longer life ( in terms of cycles) are excellent for end to end continuous motion applications offer high speed and high force capacities are relatively easy to understand and maintain don t require complicated programming Electric Actuators: offer higher levels of accuracy and repeatability are cleaner, smoother and quieter provide true motion control multi positioning, synchronized motion and speed and force control don t require compressed air to operate Our complete product catalogue, which now contains over, basic products, has been specifically developed for factory automation and process industry needs. As world leaders, we have developed a comprehensive range of pneumatic and electric actuators to meet even the most challenging of applications and our experts are always on-hand to provide you will their experienced guidance and advice.

3 SMC s new easy electric actuator products SMC s new easy electric actuator products: Recently we have launched four electric actuator products to join our existing electric and electro-pneumatic actuator ranges our LE+ Series. Series LEY - a rod type electric actuator Series LEF- a slider type electric actuator Series LES - a slide table electric actuator Series LEH - a range of electric actuator grippers Why do we refer to them as easy electric? Unlike similar products, these electric actuator ranges are extremely easy to programme. Simply by selecting the Easy Mode setting option, your selected actuator will be operating efficiently and effectively within minutes of opening the box. Unofficially we call it our programming made simple approach to electric actuation - which we believe will definitely help to dispel some the mystery surrounding this activity. Speed, Force and Positioning Control Do you suffer from: poor workpiece detection constant workpiece breakage high rejection rates due to workpiece marking on-going gripper finger breakages increased operational downtime for constant maintenance or corrective component adjustment Do you find: difficulties in controlling the actuator speed and acceleration the impact at the end of the stroke of an air operated actuator excessively abrupt the weight of air operated grippers higher than you would like that you need multiple types and sizes of air operated actuators in your application/s complications when fitting multiple auto switches to your application/s physical challenges in accommodating pneumatic airlines in your application/s Do you currently: require a high inventory of component stocks for your application/s experience high machine noise due to the constant venting of compressed air If these problems sound familiar to you, then our latest range of electric actuators can now provide you with an ideal solution. Electric Grippers LEHZ LEHF LEHS Electric Slide Table LES Electric Actuator/ Rod Type LEY Electric Actuator/ Slider Type LEF Controller LEC Programming Concepts Smooth acceleration and de-acceleration, controlled gripper force and accurate, repeatable, multi-positioning, are just a few key performance benefits you will enjoy by selecting a SMC electric actuator for your application/s. Quieter than an air operated actuators and cleaner in operation, our complete LE range of electric actuators offer excellent performance, outstanding reliability and unbelievable precision and accuracy. And, with our easy mode setting, you no longer need to be a genius to programme and experience the operational benefits of our LE product range total Speed, Force and Positioning Control. 3

4 A new generation of electric actuators to meet all your application needs The new range of electric actuators LE series add the simplicity of use to the conventional benefits of electric actuators.

29 Basic Programming Concepts Programming Concepts Basic Programming Concepts Positioning operation The actuator moves to the target position specified by the step data "Position" KEY PARAMETERS Area, Area : the AREA output signal turns ON within the range [Area, Area] In position: when the electric actuator enters the range of [in position] the INP output signal turns on Pushing operation Similar to the positioning operation, the actuator moves according to the settings of "Position" and "Speed" in the step data, and then when it reaches the target position it starts the pushing process. The actuator pushes the load with the force no more than the maximum force set in "pushing force" KEY PARAMETERS In position: the transfer distance (relative value) when pressing. If the transferred distance exceeds the setting it stops, even if it is not pressing (in which case, INP output will not be turned on, incomplete pushing). Trigger LV: the condition at which INP output is turned on. Set it at the value of the equivalent to the pusing force or less. Pushing force: pushing force ratio Pushing speed: the pushing speed whilst in pushing mode Speed Acceleration Speed Deceleration Speed Acceleration Speed Deceleration Position In position INP output ON OFF ON AREA output OFF ON OFF Pushing speed Pushing force Trigger LV Force Position In position INP output ON OFF ON Example of activation signals from PLC for each position Programming Concepts Position IN OFF IN OFF IN 3 OFF IN OFF IN OFF IN ON IN OFF IN OFF IN 3 OFF IN ON IN OFF IN ON 9

30 Basic Programming Concepts Programming tips Using absolute and relative positions If necessary, more than positions can be achieved by combining absolute positions with relative positions in different combinations Speed Acceleration Speed Deceleration For example: 3, mm can be obtained with a sequence of the following 3 positions: In position 3. In position Absolute: mm Relative: 3 mm Relative:, mm INP output ON ON ON ON Skip cycles when there is no load made simple The sequence when there is no load can be easily simplified by using a TriggerLV below which the INP output signal will not be activated. This can be used for changing the sequence and avoiding having cycles with no workpiece and improve the productivity of your system. Activate a signal without stopping the actuator Use the area functions to activate a signal between points without stopping the actuator. That will make possible to perform other processes and, in some applications, reduce the cycle time. For example, in printing systems the positions of the start and end of the printing length can be controlled with the "Area" and "Area" settings, without stopping the actuator. Limit the maximum force when required If, in certain steps of your applications, you want to reduce risks that can affect the operators or critical parts of the machine, it is possible to reduce the force during the positioning of the actuator to an acceptable level. 3
