Model Selection Information (Correlation Diagram of Speed and Load Capacity) RCP2W Series Waterproof Slider Type Caution for Use If you will be using a slider type and the load installed on the slider will project significantly from the center, consider the load moment and overhang load length. Load moment Keep Ma/Mb/Mc load moments within their specified ranges. Ma Mb Mc Select horizontal or vertical installation Overhang load length When the center of gravity of the L installed load is L/2. If the load projects in Ma, Mb or Mc direction, keep the overhang load length within the specified range. L Horizontal installation 40 35 SA16-4 Load capacity (kg) 30 25 20 15 SA16-8 10 5 0 25 50 75 100 125 150 175 200 Speed (mm/sec) (Note) The RCP2W-SA16 is not available with brake, so it cannot be used vertically. (Note) In the above diagrams, the figure after the type code indicates the lead. (Note 1) If the actual load is equal to the maximum load capacity at the applicable speed, vibration overshoot may occur. Select a model that provides an allowance of approx. 70%.

Model Selection Information (Push Force) Selection Guide Correlation (Diagrams of Push Force and Current-Limiting Value) ERC2 Series Slider type When performing push-motion operation using a slider type, limit the push current to prevent the reactive moment generated by the push force from exceeding 80% of the rated moment (Ma, Mb) specified in the catalog. The position where guide moment is applied is illustrated below to facilitate moment calculation. Calculate the moment by considering an offset required at the position where push force is applied. Since applying an excessive force exceeding the rated moment may damage the guide and shorten the service life of the actuator, set sufficient push current by considering a safety factor. SA6 : 36mm SA7 : 46mm Note The travel speed is fixed to 20 mm/s during push-motion operation. Position where moment is applied Calculation example) If a push force of 100 N is applied at the position shown to the right on the ERC2-SA7C type, the moment received by the guide is calculated as follows: Ma=(46+50)x100 =9600(N•mm) =9.6(N•m) 50mm Since the rated moment of the SA7 (Ma) is 13.8 (N-m), 13.8 x 0.8 = 11.04 > 9.6. Accordingly, the requirement is satisfied. If Mb moment generates as a result of push motion, follow the same procedure to calculate the actual moment based on the overhang load and confirm that it is within 80% of the rated moment.
