Model Selection Reference (Push Force)Selection Guide (Push Force and Electric Current Limitation Correlation Graph)When using slider type for pressing operation, limit pressing current to prevent anti-moment generated by push force from exceeding 80% of the catalog spec rating for moment (Ma, Mb).To calculate moment, use the guide moment action position shown in the figure below, and consider the amount of offset at the push force action position.Be aware that, if excess force above the rated moment is applied, the guide can be damaged and its use life can be shortened. Therefore, carefully set the current with safety in mind.ERC2 SeriesSlider TypeCaution:Note: The movement speed during pressing is fixed at 20mm/s.Moment operation positionExample of calculation:With this type, at the position shown in the figure at the right, when there is 100N of pressingthe moment received by the guide is Ma = (46 + 50) x 100= 9600 (N m)= 9.6 (N m). The SA7 rated moment is Ma = 13.8 (N m)and 13.8 x 0.8 = 11.04 > 9.6, which means it is OK.Also, when pressing generates moment Mb, use the overhang calculation to similarly confirm that the moment is within 80% of the rated moment.SA6C TypeSA7C TypePush force and current limit correlation graph * In the table below, standard figures are shown.
