SpeedThis refers to the set speed when moving the slider (or rod, arm, output axis) of the actuator.The slider accelerates from rest to the specified speed, and continues to move at that speed until it decelerates to a stop at the specified target position.<Note>For models equipped with a pulse motor (ERC2, RCP3, and RCP2), the maximum speed changes with the weight of the load being transported.When selecting an actuator, refer to the "Speed vs. Load Capacity" (on each product page).If the axis has a short stroke, or if it has a long stroke but the travel distance is short, the specified speed may not be reached.As the stroke becomes longer, the maximum speed decreases, due to hazardous RPMs. For details, see " Stroke vs. Maximum Speed" on each product page.For the RCP2 high-speed slider type (HS8C/HS8R) and belt type, vibration and/or resonance may occur when operated at low speeds. Therefore, use these models at 100mm/s or faster.For PMEC/AMEC controllers, a minimum speed is set for each actuator. See the instructions manual for the PMEC/AMEC controllers.When calculating the time travelled, take into account the time taken to accelerate, decelerate, and converge, as opposed to only the time travelled at the specific speed.2. Acceleration/DecelerationAcceleration is the rate of change in speed from rest until a specified speed is reached. Deceleration is the rate of change in speed from the specified speed to a state of rest. Both are specified in "G" in programs (0.3G = 2940mm/sec2).* For rotary type, 0.3G = 2940 degrees/sec2<Note>Increasing the acceleration (deceleration) speeds up acceleration (deceleration), shortening the travel time.However, caution should be exercised, as excessively high acceleration/deceleration may cause an error or a malfunction.The rated acceleration (deceleration) is 0.3G (2.0G, if the lead is 2.5, 3, or 4, or if used vertically)With the exception of the high-acceleration/deceleration model, use the actuators at or below the rated acceleration.For models such as RCS2-SRA7 and RCS2-RA13R, use the actuator at or below the acceleration (deceleration) mentioned in "Notes on Selection" on the respective product page.3. DutyIAI’s actuators should be used at a duty of 50% or below.If used at over 50% duty, an excessive load error may occur depending on the load, speed, or acceleration.4. Positioning RepeatabilityA JIS B6192-compliant method for evaluating performance.In this method, a positioning operation (stopping of the actuator at target point) is repeated seven times from the same direction, each time measuring the end position. Then the difference between the maximum and minimum values is calculated.By using this measuring method for both end-points and the mid-point of the maximum stroke, the largest calculated value is multiplied by 1/2 and expressed with a ±.utitoionnaaryryNNootetesPre-41 RoboCylinder General Catalogue
